The Techno-Humanist Compass: Shaping a Better AI Future

Superagency: What Could Possibly Go Right with Our AI Future written by Reid Hoffman 

Hoffman argues that humanity is in the early stages of an “existential reckoning” with AI, akin to the Industrial Revolution. While new technologies have historically sparked fears of dehumanization and societal collapse, the author maintains a “techno-humanist compass” is essential to navigate this era. This compass prioritizes human agency – our ability to make choices and exert influence – and aims to broadly augment and amplify individual and collective agency through AI.

Key Themes & Ideas:

• Historical Parallelism: New technologies throughout history (printing press, automobile, internet) have faced skepticism and opposition before becoming mainstays. Similarly, current fears surrounding AI, including job displacement and extinction-level threats, echo past anxieties.
• The Inevitability of Progress: “If a technology can be created, humans will create it.” Attempts to halt or prohibit technological advancement are ultimately futile and counterproductive.
• Techno-Humanism: Technology and humanism are “integrative forces,” not oppositional. Every new invention redefines and expands what it means to be human.
• Human Agency as the Core Concern: Most concerns about AI, from job displacement to privacy, are fundamentally questions about human agency. The goal of AI development should be to broadly augment and amplify individual and collective agency.
• Iterative Deployment: A key strategy, pioneered by OpenAI, for developing and deploying AI is “iterative deployment.” This involves incremental releases, gathering user feedback, and adapting as new evidence emerges. It prioritizes flexibility over a grand master plan.
• Beyond Doom and Gloom: The author categorizes perspectives on AI into “Doomers” (extinction threat), “Gloomers” (near-term risks, top-down regulation), “Zoomers” (unfettered innovation, skepticism of regulation), and “Bloomers” (optimistic, mass engagement, iterative deployment). Hoffman aligns with the “Bloomer” perspective.

Important Facts:

• Unemployment rates are lower today than in 1961, despite widespread automation in the 1950s.
• ChatGPT, launched with “zero marketing dollars,” attracted “one million users in five days” and “100 million users in just two months.”
• Some AI models, even “state-of-the-art” ones, “hallucinate”—generating false information or misleading outcomes. This occurs because LLMs “never know a fact or understand a concept in the way that we do,” but rather “make a prediction about what tokens are most likely to follow” in a contextually relevant way.
• US public opinion on AI is generally cautious: “only 15 percent of U.S. adults said they were ‘more excited than concerned’” in a 2023 Pew Research Center survey.

II. Big Knowledge, Private Commons, and Networked Autonomy

The book elaborates on how AI can convert “Big Data into Big Knowledge,” transforming various aspects of society, from mental health to governance, and fostering a “private commons” that expands individual and collective agency.

Key Themes & Ideas:

• The “Light Ages” of Data: In contrast to George Orwell’s dystopian vision in “1984,” where technology enables “God-level techno-surveillance,” Hoffman argues that big knowledge, enabled by computers and AI, leads to a “Light Ages of data-driven clarity and growth.”
• Beyond “Extraction Operations”: The author refutes the notion that Big Tech’s use of data is primarily “extractive.” Instead, he views it as “data agriculture” or “digital alchemy,” where repurposing and synthesizing data creates tremendous value for users and society, a “mutualistic ecosystem.”
• The Triumph of the Private Commons: Platforms like Google Maps, YouTube, and LinkedIn, though privately owned, function as “private commons,” offering free or near-free “life-management resources that effectively function as privatized social services and utilities.”
• Consumer Surplus: The value users derive from these private commons often far exceeds the explicit costs, creating significant “consumer surplus.”
• Informational GPS: LLMs act as “informational GPS,” helping individuals navigate complex and expanding informational environments, enhancing “situational fluency” and enabling better-informed decisions.
• Upskilling and Democratization: AI, particularly LLMs, can rapidly upskill beginners and democratize access to high-value services (education, healthcare, legal advice) for underserved communities.
• Networked Autonomy and Liberating Limits: The historical evolution of automobiles demonstrates how regulation, when thoughtfully applied and coupled with innovation, can expand individual freedom and agency by creating safer, more predictable, and scalable systems. Similarly, new regulations and norms for AI will emerge to manage its power while ultimately expanding autonomy.

Important Facts:

• In 1963, the IRS collected $700,000 in unpaid taxes after announcing it would use an IBM 7074 to process returns.
• Vance Packard’s 1964 bestseller, “The Naked Society,” expressed fears of “giant memory machines” recalling “every pertinent action” of citizens.
• The median compensation Facebook users were willing to accept to give up the service for one month was $48, while Meta’s average annual revenue per user (ARPU) in 2023 was $44.60, suggesting a significant “consumer surplus.”
• The amount of data produced globally in 2024 is “roughly 402 billion gigabytes per day,” enough to fill “2.3 billion books per second.”
• Studies in 2023 showed that professionals using ChatGPT completed tasks “37 percent faster,” with “the quality boost bigger for participants who received a low score on their first task.” Less experienced customer service reps saw productivity increases of “14 percent.”
• The US federal government passed the Infrastructure Investment and Jobs Act in 2021, which includes a provision for mandatory “Driver Alcohol Detection System for Safety (DADSS)” in new cars, potentially by 2026.
• The US Interstate Highway System (IHS), initially authorized for 41,000 miles in 1956, now encompasses over 48,000 miles and creates “annual economic value” of “$742 billion.”

III. Innovation, Safety, and the Social Contract

Hoffman posits that innovation itself is a form of safety, and that successful AI integration will require a renewed social contract and active citizen participation in shaping its development and governance.

Key Themes & Ideas:

• Innovation as Safety: Rapid, adaptive development with short product cycles and frequent updates leads to safer products. “Innovation is safety” in contrast to the “precautionary principle” (“guilty until proven innocent”) favored by some critics.
• Competition as Regulation: Benchmarks and public leaderboards (like Chatbot Arena) serve as “dynamic mechanisms for driving progress” and promote transparency and accountability in AI development, effectively “regulation, gamified.”
• Law Is Code: Lawrence Lessig’s thesis that “code is law” is more relevant than ever as AI-enabled “perfect control” becomes possible in physical spaces (e.g., smart cars, instrumented public venues).
• The Social Contract and Consent of the Governed: The successful integration of AI, especially agentic systems, requires a robust “social contract” and the “consent of the governed.” Voluntary compliance and public acceptance are crucial for legitimacy and stability.
• Rational Discussion at Scale: AI can be used to enhance civic participation and collective decision-making, moving beyond traditional surveillance models to enable “rational discussion at scale” and build consensus.
• Sovereign AI: Nations will increasingly seek to “own the production of their own intelligence” to protect national security, economic competitiveness, and cultural values.

Important Facts:

• The Future of Life Institute’s letter called for a pause on AI development until systems were “safe beyond a reasonable doubt,” reversing the standard of criminal law.
• Chatbot Arena, an “open-source platform,” allows users to “vote for the one they like best” between two unidentified LLMs, creating a public leaderboard.
• MSG Entertainment uses facial recognition to deny entry to attorneys from firms litigating against it.
• South Korea’s Covid-19 response relied on extensive data collection (mobile GPS, credit card transactions, travel records) and transparent sharing, demonstrating how “public outrage has been nearly nonexistent” due to “a radically transparent version of people-tracking.”
• Jensen Huang (Nvidia CEO) stated that models are likely to grow “1,000 to 10,000 times more powerful over the next decade,” leading to “highly skilled virtual programmers, engineers, scientists.”

Conclusion: A Path to Superagency

Hoffman concludes by reiterating the core principles: designing for human agency, leveraging shared data as a catalyst for empowerment, and embracing iterative deployment for safe and inclusive AI. The ultimate goal is “superagency,” where individuals and institutions are empowered by AI, leading to compounding benefits across society, from mental health to scientific discovery and economic opportunity. This future requires an “exploratory, adaptive, forward-looking mindset” and a collective commitment to shaping AI with a “techno-humanist compass” that prioritizes human flourishing.

III. Answer Key (for Quiz)

1. The techno-humanist compass is a dynamic guiding principle that aims to orient technology development towards broadly augmenting and amplifying individual and collective human agency. It’s crucial because it ensures that technological innovations, like AI, actively enhance what it means to be human, rather than being presented as oppositional forces.
2. Iterative deployment is OpenAI’s method of introducing new AI products incrementally, without advance notice or excessive hype, and then using continuous public feedback to inform ongoing development efforts. This approach allows society to adapt to changes, builds trust through exposure, and gathers diverse user input for improvement.
3. Doomers fear extinction-level threats from superintelligent AI, while Gloomers focus on near-term risks like job loss and advocate for prohibitive regulation. Zoomers are optimistic about AI’s benefits and want innovation without government intervention, whereas Bloomers (the authors’ stance) are optimistic but believe mass engagement and continuous feedback are essential for safe, equitable, and useful AI.
4. LLMs do not “know a fact” or “understand a concept” in the human sense. Instead, they make statistically probable predictions about what tokens (words or fragments) are most likely to follow others in a given context, based on patterns learned from their training data.
5. The “black box phenomenon” refers to the opaque way complex neural networks operate, identifying patterns that human overseers struggle to discern, making it hard or impossible to explain a model’s outputs or trace its decision-making process. This presents a challenge for building trust and ensuring accountability.
6. Packard feared that mainframe computers would lead to “humanity in chains” due to data collection, but the authors argue the personal computer actually liberated individuals by enabling self-expression and diverse lifestyles. Big Business used data to personalize services, making people feel “seen” rather than oppressed, which led to a more diverse and inclusive world.
7. Consumer surplus is the difference between what people pay for a product or service and how much they value it. In the digital economy, free “private commons” services (like Wikipedia or Google Maps) generate massive consumer surplus because users place a high value on them despite paying nothing.
8. The authors argue that “innovation is safety” because rapid, adaptive development, with shorter product cycles and frequent updates, allows for quicker identification and correction of issues, leading to safer products more effectively than static, precautionary regulations. This approach is exemplified by how the internet fosters continuous improvement through feedback loops.
9. Informational GPS (LLMs) can democratize access by providing: 1) context and guidance for college applications to low-income students who lack access to expensive human tutors, and 2) immediate explanations of complex legal documents (like “rent arrearage”) in a non-native speaker’s own language, potentially even suggesting next steps or legal aid.
10. As the physical and virtual worlds merge, code as law means that physical devices (like cars with alcohol-detection systems or instrumented national parks) are increasingly embedded with software that dictates behavior and enforces rules automatically. This level of “perfect control” extends beyond cyberspace, directly impacting real-world choices and obligations in granular ways.

Executive Summary

Melanie Mitchell’s Artificial Intelligence: A Guided Tour offers a comprehensive and critical examination of the current state of AI, highlighting its impressive advancements in narrow domains while robustly arguing that true human-level general intelligence remains a distant goal. The author, a long-time AI researcher, frames her exploration through the lens of a pivotal 2014 Google meeting with AI legend Douglas Hofstadter, whose “terror” at the shallow nature of modern AI’s achievements sparked Mitchell’s deeper investigation.

The book traces the history of AI from its symbolic roots to the current dominance of deep learning and machine learning. It delves into key AI applications such as computer vision, game-playing, and natural language processing, showcasing successes but consistently emphasizing their limitations. A central theme is the “barrier of meaning” – the profound difference between human understanding, grounded in common sense, abstraction, and analogy, and the pattern-matching capabilities of even the most sophisticated AI systems. Mitchell expresses concern about overestimating AI’s current abilities, its brittleness, susceptibility to bias and adversarial attacks, and the ethical implications of deploying such systems without full awareness of their limitations. Ultimately, she posits that general human-level AI is “really, really far away” and will likely require a fundamental shift in approach, potentially involving embodiment and more human-like cognitive mechanisms.

Main Themes and Key Ideas/Facts

1. The Enduring Optimism and Recurring “AI Winters”

• Early Optimism and Overpromising: From its inception at the 1956 Dartmouth workshop, AI has been characterized by immense optimism and bold predictions of imminent human-level intelligence. Pioneers like Herbert Simon predicted machines would “within twenty years, be capable of doing any work that a man can do” (Chapter 1).
• The Cycle of Hype and Disappointment: AI’s history is marked by a “repeating cycle of bubbles and crashes.” New ideas generate optimism, funding pours in, but “the promised breakthroughs don’t occur, or are much less impressive than promised,” leading to “AI winter” (Chapter 1).
• Current “AI Spring”: The last decade has seen a resurgence, dubbed “AI spring,” driven by deep learning’s successes, with tech giants investing billions and experts once again predicting near-term human-level AI (Chapter 3).

2. The Distinction Between Narrow/Weak AI and General/Strong AI

• Narrow AI’s Successes: Current AI, even in its most impressive forms like AlphaGo or Google Translate, is “narrow” or “weak” AI, meaning it “can perform only one narrowly defined task (or a small set of related tasks)” (Chapter 3). Examples include:
• IBM’s Deep Blue defeating Garry Kasparov in chess (1997), and later its Watson program winning Jeopardy! (2011).
• DeepMind’s AlphaGo mastering Go (2016).
• Advances in speech recognition, Google Translate, and automated image captioning (Chapter 3, 11, 12).
• Lack of General Intelligence: “A pile of narrow intelligences will never add up to a general intelligence. General intelligence isn’t about the number of abilities, but about the integration between those abilities” (Chapter 3). These systems cannot “transfer” what they’ve learned from one task to a different, even related, task (Chapter 10).
• The “Easy Things Are Hard” Paradox: Tasks easy for young children (e.g., natural language conversation, describing what they see) have proven “harder for AI to achieve than diagnosing complex diseases, beating human champions at chess and Go, and solving complex algebraic problems” (Chapter 1). “In general, we’re least aware of what our minds do best” (Chapter 1).

3. Deep Learning: Its Power and Limitations

• Dominant Paradigm: Since the 2010s, deep learning (deep neural networks) has become the “dominant AI paradigm” and is often inaccurately equated with AI itself (Chapter 1).
• How Deep Learning Works (Simplified): Inspired by the brain’s visual system, Convolutional Neural Networks (ConvNets) use layers of “units” to detect increasingly complex features in data (e.g., edges, then shapes, then objects in images). Recurrent Neural Networks (RNNs) process sequences like sentences, “remembering” context through recurrent connections (Chapter 4, 11).
• Supervised Learning and Big Data: Deep learning’s success heavily relies on “supervised learning,” where systems are trained on massive datasets of human-labeled examples (e.g., ImageNet for computer vision, sentence pairs for translation). This requires “a huge amount of human effort… to collect, curate, and label the data, as well as to design the many aspects of the ConvNet’s architecture” (Chapter 6).
• The “Alchemy” of Hyperparameter Tuning: Optimizing deep learning systems is not a science but “a kind of alchemy,” requiring specialized “network whispering” skills to tune “hyperparameters” (e.g., number of layers, learning rate) (Chapter 6).
• Lack of Human-like Learning: Unlike children who learn from few examples, deep learning requires millions of examples and passive training. It doesn’t learn “on its own” in a human-like sense or infer abstractions and connections between concepts (Chapter 6).
• Brittleness and Vulnerability: Even successful AI systems are “brittle” and prone to errors when inputs deviate slightly from training data.
• Overfitting: ConvNets “overfitting to their training data and learning something different from what we are trying to teach them,” leading to poor performance on novel, slightly different images (Chapter 6).
• Long-tail Problem: Real-world scenarios have a “long tail” of unlikely but possible situations not present in training data, making systems vulnerable (e.g., self-driving cars encountering unusual road conditions) (Chapter 6).
• Adversarial Examples: Deep neural networks are “easily fooled” by “adversarial examples” – minuscule, human-imperceptible changes to inputs that cause confident misclassification (e.g., school bus as ostrich, modified audio transcribing to malicious commands) (Chapter 6, 13).

4. The “Barrier of Meaning”: What AI Lacks

• Absence of Understanding: A core argument is that no AI system “yet possesses such understanding” that humans bring to situations. This lack is revealed by “un-humanlike errors,” “difficulties with abstracting and transferring,” “lack of commonsense knowledge,” and “vulnerability to adversarial attacks” (Chapter 14).
• Common Sense (Intuitive Knowledge): Humans possess innate and early-learned “core knowledge” or “common sense” in intuitive physics, biology, and psychology. This allows understanding of object behavior, living things, and other people’s intentions (Chapter 14). This is “missing in even the best of today’s AI systems” (Chapter 7).
• Efforts like Douglas Lenat’s Cyc project to manually encode common sense have been “heroic” but ultimately “not led to an AI system being able to master even a simple understanding of the world” (Chapter 15).
• Abstraction and Analogy: These are “two fundamental human capabilities” crucial for forming concepts and understanding new situations. Abstraction involves recognizing specific instances as part of a general category, while analogy is “the perception of a common essence between two things” (Chapter 14). Current AI systems, including ConvNets, “do not have what it takes” for human-like abstraction and analogy-making, even in idealized problems like Bongard puzzles (Chapter 15).
• The author’s own work, like the Copycat program, aimed to model these abilities but “only scratched the surface” (Chapter 15).
• The Role of Embodiment: The “embodiment hypothesis” suggests that human-level intelligence requires a body that interacts with the world. Without physical experience, a machine may “never be able to learn all that’s needed” for robust understanding (Chapter 3, 15).

5. Ethical Considerations and Societal Impact

• The Great AI Trade-Off: Society faces a dilemma: embrace AI’s benefits (e.g., health care, efficiency) or be cautious due to its “unpredictable errors, susceptibility to bias, vulnerability to hacking, and lack of transparency” (Chapter 7).
• Bias in AI: AI systems reflect and can magnify biases present in their training data (e.g., face recognition systems being less accurate on non-white or female faces; word vectors associating “computer programmer” with “man” and “homemaker” with “woman”) (Chapter 6, 11).
• Explainable AI: The “impenetrability” of deep neural networks, making it difficult to understand how they arrive at decisions, is “the dark secret at the heart of AI.” This lack of transparency hinders trust and makes predicting/fixing errors difficult (Chapter 6).
• Moral AI: Programming machines with a human-like sense of morality for autonomous decision-making (e.g., self-driving car “trolley problem” scenarios) is incredibly challenging, requiring the very common sense that AI lacks (Chapter 7).
• Regulation: There’s a growing call for AI regulation, but challenges include defining “meaningful information” for explanations and who should regulate (Chapter 7).
• Job Displacement: While AI has historically automated undesirable jobs, the potential for massive unemployment, especially in fields like driving, remains a significant, though uncertain, concern (Chapter 7, 16).
• “Machine Stupidity” vs. Superintelligence: The author argues that the immediate worry is “machine stupidity” – machines making critical decisions without sufficient intelligence – rather than an imminent “superintelligence” that “will take over the world” (Chapter 16).

6. The Turing Test and the Singularity

• Turing Test Controversy: Alan Turing’s “imitation game” proposes that if a machine can be indistinguishable from a human in conversation, it should be considered to “think.” However, experts largely dismiss recent “wins” (like Eugene Goostman) as “publicity stunts” based on superficial trickery and human anthropomorphism (Chapter 3).
• Ray Kurzweil’s Singularity: Kurzweil, a prominent futurist and Google engineer, predicts an “AI Singularity” by 2045, where AI “exceeds human intelligence” due to “exponential progress” in technology (Chapter 3).
• Skepticism of the Singularity: Mitchell, like many AI researchers, is “dismissively skeptical” of Kurzweil’s predictions, arguing that software progress hasn’t matched hardware, and he vastly underestimates the complexity of human intelligence (Chapter 3). Hofstadter also expressed “terror” that this vision trivializes human depth (Prologue).
• “Prediction is hard, especially about the future”: The timeline for general AI is highly uncertain, with estimates ranging from decades to “never” among experts (Chapter 16).

Conclusion

Melanie Mitchell’s book serves as a vital call for realism in the discourse surrounding AI. While acknowledging the remarkable utility and commercial success of deep learning in specific domains, she persistently underscores that these achievements do not equate to human-level understanding or general intelligence. The “barrier of meaning,” rooted in AI’s lack of common sense, abstraction, and analogy-making abilities, remains a formidable obstacle. The book urges a cautious and critical approach to AI deployment, emphasizing the need for robust, transparent, and ethically considered systems, and reminds readers that the true complexity and subtleties of human intelligence are often underestimated.

III. Answer Key (for Quiz)

1. The primary goal of the 1956 Dartmouth workshop was to explore the possibility of creating thinking machines, based on the conjecture that intelligence could be precisely described and simulated. Its lasting contribution was coining the term “artificial intelligence” and outlining the field’s initial research agenda.
2. “Intelligence” is a “suitcase word” because it’s packed with various, often ambiguous meanings (emotional, logical, artistic, etc.), making it hard to define precisely. This lack of a universally accepted definition has paradoxically allowed AI to grow rapidly by focusing on practical task performance rather than philosophical agreement.
3. Symbolic AI programs use human-understandable words or phrases and explicit rules to process them, like the General Problem Solver (GPS) for logic puzzles. Subsymbolic AI, inspired by neuroscience, uses numerical operations and learns from data, with the perceptron for digit recognition as an early example.
4. Minsky and Papert mathematically proved that simple perceptrons had very limited problem-solving capabilities and speculated that multilayer networks would be “sterile.” This criticism, alongside overpromising by AI proponents, led to funding cuts and a slowdown in neural network research, known as an “AI Winter.”
5. The “easy things are hard” paradox means that tasks effortlessly performed by young children (e.g., natural language understanding, common sense) are extremely difficult for AI, while tasks difficult for humans (e.g., complex calculations, chess mastery) are easy for computers. This highlights the hidden complexity of human cognition.
6. ImageNet provided a massive, human-labeled dataset of images for object recognition, which was crucial for training deep convolutional neural networks. Amazon Mechanical Turk enabled the efficient and cost-effective labeling of millions of images, overcoming a major bottleneck in data collection.
7. Claims of AI surpassing humans on ImageNet are often based on “top-5 accuracy,” meaning the correct object is just one of five guesses, rather than the single top guess. Additionally, the human error rate benchmark was derived from a single researcher’s performance, not a representative human group, and machines may rely on superficial correlations rather than true understanding.
8. Adversarial examples are subtly modified input data (e.g., altered pixels in an image, a few changed words in text) that are imperceptible to humans but cause a deep neural network to misclassify with high confidence. A real-world implication is the potential for malicious attacks on self-driving car vision systems by placing inconspicuous stickers on traffic signs.
9. Supervised learning requires large datasets where each input is explicitly paired with a correct output label, allowing the system to learn by minimizing error. Reinforcement learning, in contrast, involves an agent performing actions in an environment and receiving only intermittent rewards, learning which actions lead to long-term rewards through trial and error without explicit labels.
10. AlphaGo is considered an “idiot savant” because its superhuman Go-playing abilities are extremely narrow; it cannot transfer any of its learned skills to even slightly different games or tasks. It lacks the general ability to think, reason, or plan beyond the specific domain of Go, which is fundamental to human intelligence.

IV. Essay Format Questions (No Answers Provided)

2. Critically analyze the claims of AI systems achieving “human-level performance” in domains like object recognition (ImageNet) and machine translation. What caveats and limitations does Melanie Mitchell identify in these claims, and what do they reveal about the difference between statistical correlation and genuine understanding?
3. Compare and contrast symbolic AI and subsymbolic AI as fundamental approaches to achieving artificial intelligence. Discuss their respective strengths, weaknesses, and the impact of Minsky and Papert’s Perceptrons on the trajectory of subsymbolic research.
4. Melanie Mitchell dedicates a significant portion of the text to the “barrier of meaning.” Explain what she means by this phrase and how various limitations of current AI systems (e.g., adversarial examples, long-tail problem, lack of explainability, struggles with Winograd Schemas) illustrate AI’s inability to overcome this barrier.
5. Douglas Hofstadter and other “Singularity skeptics” express terror or concern about AI, but for reasons distinct from those often portrayed in science fiction. Describe Hofstadter’s specific anxieties about AI progress and contrast them with what Melanie Mitchell identifies as the “real problem” in the near-term future of AI.

• Singularity: A hypothetical future point in time when technological growth becomes uncontrollable and irreversible, resulting in unfathomable changes to human civilization, often associated with AI exceeding human intelligence.
• SQuAD (Stanford Question Answering Dataset): A large dataset used to benchmark machine reading comprehension, where questions about Wikipedia paragraphs are designed such that the answer is a direct span of text within the paragraph.
• Strong AI: See Artificial General Intelligence. (Note: John Searle’s definition differs, referring to AI that literally has a mind.)
• Subsymbolic AI: An approach to AI that takes inspiration from biology and psychology, using numerical, brain-like processing (e.g., neural networks) rather than explicit, human-understandable symbols and rules.
• Suitcase Word: A term coined by Marvin Minsky for words like “intelligence,” “thinking,” or “consciousness” that are “packed” with multiple, often ambiguous meanings, making them difficult to define precisely.
• Superhuman Intelligence (Superintelligence): An intellect that is much smarter than the best human brains in virtually every field, including scientific creativity, general wisdom, and social skills.
• Supervised Learning: A machine learning paradigm where an algorithm learns from a “training set” of labeled data (input-output pairs), with a “supervision signal” indicating the correct output for each input.
• Symbolic AI: An approach to AI that attempts to represent knowledge using human-understandable symbols and manipulate these symbols using explicit, logic-based rules.
• Temporal Difference Learning: A method used in reinforcement learning (especially deep Q-learning) where the learning system adjusts its predictions based on the difference between successive estimates of the future reward, essentially “learning a guess from a better guess.”
• Test Set: A portion of a dataset used to evaluate the performance of a machine learning model after it has been trained, to assess its ability to generalize to new, unseen data.
• Theory of Mind: The human ability to attribute mental states (beliefs, intentions, desires, knowledge) to oneself and others, and to understand that these states can differ from one’s own.
• Thought Vectors: Vector representations of entire sentences or paragraphs, analogous to word vectors, intended to capture their semantic meaning.
• Training Set: A portion of a dataset used to train a machine learning model, allowing it to learn patterns and relationships.
