Expert Systems (Traditional AI): Hand-coded knowledge in the form of rules. Can’t handle the unexpected and are brittle. Limited to solutions that programmers can express. Inspired by logic systems and logic theory.
Learning Systems (Modern AI): Learn solutions from first principles and directly from data and experience. Can generalize to new tasks and potentially solve problems we don’t know how to. Inspired by neuroscience and how the brain works.
00:06:53 Learning and Generality: Key Concepts for Developing Intelligent AI Systems
Deep Blue vs. Garry Kasparov: Deep Blue, an expert system, defeated Garry Kasparov, the world chess champion, in the late 1990s. Kasparov’s creativity and ability to play other games and perform various tasks made him more impressive. Deep Blue’s hard-coded specialization limited it to chess and prevented it from playing simpler games.
Reinforcement Learning: Reinforcement learning systems learn from first principles through trial and error. Agents in reinforcement learning systems interact with the environment through sensory apparatus and receive observations and rewards. Agents build statistical models of the environment to understand linkages and make decisions. Reinforcement learning focuses on learning general skills that can be applied to various tasks. DeepMind’s AlphaGo defeated Lee Sedol, the world’s top Go player, in 2016. AlphaGo was able to learn and adapt to new games with minimal data, demonstrating its generality.
00:10:48 How Reinforcement Learning Powers General Intelligence
The Agent System: An agent system consists of two parts: a model of the world and an action selector. The model of the world continually updates based on new observations. The action selector chooses the best action to take to achieve the goal.
The Reinforcement Learning Cycle: The agent runs out of thinking time and outputs the best action found so far. The action gets executed and may drive a new change in the environment. The agent updates its model of the world and selects a new action. This cycle continues until the agent reaches its goal.
Challenges of Reinforcement Learning: There are many technical challenges that need to be solved to implement reinforcement learning effectively. The dopamine system in the primate and human brain implements a form of reinforcement learning.
Games as a Proving Ground for AI Algorithms: Games are an ideal platform for developing and testing AI algorithms. They offer a diverse range of challenges and allow for rapid experimentation. Virtual simulations in games are more convenient than robotics for AI development.
Atari 2600 as a Testbed for Reinforcement Learning: The Atari 2600 was the first console with a large diversity of games. The DQN agent system was tested on Atari games in 2013. The DQN agent only receives raw pixels as input and learns everything from scratch.
Generality of Reinforcement Learning: The goal is to develop a single system that can play all different games out of the box. The DQN agent system successfully learned to play Breakout, a seminal game on the Atari system. The system improved over time as it gained more experience playing the game.
00:15:39 Reinforcement Learning Systems for Game Mastery
Optimal Breakout Strategy: After 300 games of Breakout, the AI discovered a hidden optimal strategy: digging a tunnel on the left side and sending the ball behind the brick wall. This tactic is low-risk and highly rewarding, allowing the AI to hit multiple bricks with one shot. The discovery of this strategy was a significant milestone for DeepMind, as it showed that their AI could learn and develop strategies beyond what was explicitly programmed.
AlphaGo: AlphaGo is a program that uses reinforcement learning to play the ancient game of Go. Go is a complex and strategic game played on a 19×19 grid, with players taking turns placing black and white stones on the board. Go has a long history and is considered a form of art in Asia, with Confucius including it among the four great arts for scholars.
Significance of AlphaGo: AlphaGo’s victory over world champion Lee Sedol in 2016 was a major breakthrough in the field of artificial intelligence. It demonstrated that AI could master complex games that require strategic thinking, intuition, and creativity. AlphaGo’s success opened up new possibilities for AI research and applications in various domains.
00:17:50 Complexity and Beauty of the Ancient Game of Go
Go as an Art Form: Go is considered a profound art form, with 40 million active players and 2,000 professionals. The game’s simplicity, with only two rules, contrasts with its immense complexity, resulting in 10 to the power 170 possible ball positions. This complexity and esoteric nature make Go a challenging game for computers to play.
Rules of Go: Go is played by placing stones on a board one at a time until the board is filled. The goal is to wall off empty areas of territory and count the number of squares surrounded compared to the opponent. The person who surrounds the most squares wins the game.
Challenges for Computers in Go: The enormous number of possible positions (10 to the power 170) makes Go a much harder game for computers compared to chess. Unlike chess, Go lacks a handcrafted evaluation function that allows computers to determine the winning side in the current position. This makes it difficult for computers to evaluate the strength of different moves and make optimal decisions during gameplay.
00:20:14 Neural Networks Enable AlphaGo to Conquer Go's Complexity
Go’s Complexity and Intuition: Go’s complexity and esoteric nature make it challenging to define a rule-based system for AI to play. Unlike chess, Go players often rely on intuition and feel, making it difficult to articulate their move choices.
AlphaGo’s Learning Systems: AlphaGo employs learning systems, including two neural networks, to address Go’s complexity and intuitive nature.
Policy Network: The policy network analyzes the current board position and identifies the most likely moves. It reduces the vast search space by focusing on the most promising moves.
Value Network: The value network evaluates the current board position and predicts the probability of each player winning. It provides a numerical assessment of the game’s state and helps AlphaGo make informed decisions.
Combining the Neural Networks: AlphaGo combines the policy and value networks to solve the challenges presented by Go. The system leverages both intuition (learned from millions of games) and calculation (evaluating board positions) to make strategic moves.
00:23:02 AlphaGo's Unconventional Strategy in the Game of Go
AlphaGo’s Victory Over Lee Sedol: AlphaGo, a computer program, defeated Lee Sedol, one of the greatest Go players in history, in a million-dollar challenge match in 2016. This was a significant achievement as no Go program had ever defeated a professional player before, let alone a world champion. The match’s outcome was proclaimed a decade ahead of its time and marked a turning point in AI development.
AlphaGo’s Unique Strategy: AlphaGo’s approach to the game was distinct from traditional Go strategies used by professionals. In game two, AlphaGo made a surprising move (move 37) by placing a stone on the fifth line early in the game, which is unconventional and considered suboptimal.
Move 37’s Significance: This move, seemingly wasteful, proved to be decisive in AlphaGo’s victory. 100 moves later, two stones placed by AlphaGo in the bottom left corner interacted with the stone placed in move 37, leading to a strategic advantage. AlphaGo’s foresight and ability to plan moves 100 steps ahead were remarkable and contributed to its overall win.
00:26:21 Exploring the Essence of Intuition and Creativity in the Context of AI and Go
Gameplay and Creativity: In Go, originality and creativity are judged by the effectiveness of a move, which is determined by the outcome of the game. AlphaGo’s move 37 in its match with Lee Sedol was initially considered a mistake by expert commentators, but later analysis revealed it to be an effective and creative move.
Lee Sedol’s Move 78: Lee Sedol’s move 78 in game four against AlphaGo, known as the “wedge move,” was a brilliant move that allowed him to win the game. AlphaGo’s networks misjudged this move, leading to its defeat.
Greg Coase’s Documentary: Greg Coase’s award-winning documentary provides insights into the human emotions and spirit of endeavor behind the AlphaGo-Lee Sedol match.
Lee Sedol’s Perspective on AlphaGo’s Creativity: After the match, Lee Sedol acknowledged AlphaGo’s creativity, recognizing that move 37 was a beautiful and creative move, beyond mere probability calculation.
Demis Hassabis’ Definition of Intuition: Intuition is implicit knowledge acquired through experience that is not consciously accessible or expressible. The quality of intuition can be tested behaviorally, such as by evaluating the quality of a move in a game like Go.
Interpolation: Interpolation is a type of creativity where a new idea is created by averaging or finding a common ground among existing examples. Machine learning systems excel at interpolation due to their ability to analyze data and identify patterns.
Extrapolation: Extrapolation is a higher level of creativity where new ideas are created by extending the boundaries of existing knowledge or examples. AlphaGo-like systems are capable of extrapolation, generating new strategies and moves beyond what human designers anticipated.
Invention or Innovation: Invention or innovation is the highest level of creativity, where entirely new concepts or ideas are created, often outside the boundaries of existing knowledge. No AI systems have yet achieved true invention, such as creating a completely new game like Go or chess.
Machine Creativity: Neural network systems are proficient at interpolation due to their statistical nature and ability to identify patterns in data. AlphaGo-like systems are advancing in extrapolation, demonstrating the ability to generate novel ideas beyond human knowledge.

AI and Creativity: A DeepMind Perspective
DeepMind’s mission, as articulated by Hassabis, is to unravel the intricacies of intelligence and harness it to address complex challenges. This endeavor has led to significant advancements in AI, particularly in learning systems that adapt and generalize beyond hard-coded expertise. A prime example is AlphaGo’s victory over Go grandmaster Lee Sedol, where the AI demonstrated creativity and strategic depth. Hassabis emphasizes the role of neural networks in this achievement, with AlphaGo employing a policy network for predicting moves and a value network for assessing positions, thus navigating the complexities of Go.
Go’s Complexity and Intuition:
Go’s intricate nature makes it challenging to define a rule-based system for AI to play. Unlike chess, Go players often rely on intuition and feel, making it difficult to articulate their move choices. AlphaGo tackles this by utilizing learning systems, including two neural networks. The policy network analyzes the current board position and identifies the most promising moves, significantly reducing the vast search space. Meanwhile, the value network evaluates the current board position and predicts the probability of each player winning, providing a numerical assessment of the game’s state and helping AlphaGo make informed decisions. By combining these networks, AlphaGo solves the challenges presented by Go, leveraging both intuition (learned from millions of games) and calculation (evaluating board positions) to make strategic moves.
Interpolation, Extrapolation, and Invention in Machine Creativity:
Machine learning systems like AlphaGo excel at interpolation, finding commonalities among existing examples. They are also capable of extrapolation, generating strategies beyond human anticipation. However, true invention, creating entirely new concepts, remains a challenge for AI.
The Evolution of AI Learning Systems
Earlier AI systems like Deep Blue, which defeated chess champion Garry Kasparov, lacked learning capabilities and adaptability. In contrast, modern AI systems use reinforcement learning, a trial-and-error approach where agents interact with their environment and build knowledge from scratch. This approach, inspired by the human brain’s dopamine system, allows AI to develop novel strategies, as seen in the AI’s unexpected tactics in the Atari game Breakout.
An Agent System:
Reinforcement learning systems can be viewed as agents consisting of two parts: a model of the world and an action selector. The model updates continually based on new observations, while the action selector chooses the best action to achieve the goal. The reinforcement learning cycle involves the agent running out of thinking time, executing the best action found, updating its world model, and selecting a new action. This cycle continues until the goal is reached. The dopamine system in the primate and human brain exemplifies a biological implementation of reinforcement learning.
From Games to Real-World Applications
Games have served as crucial testing grounds for AI, allowing for the development of algorithms in controlled, virtual environments. This approach has led to AI systems like the DQN agent, which learns from raw pixel input, as demonstrated in Atari Breakout. Beyond games, these AI technologies find applications in various fields, including healthcare, education, and scientific research, addressing challenges like exoplanet discovery and medical diagnostics.
AI has a wide range of commercial applications, including healthcare, medical diagnostics, optimization, energy, education, and virtual assistants. It has also been used in art and design, such as architecture, car engine design, and art transfer. In the realm of scientific research, AI’s contributions include discovering exoplanets, controlling plasma in nuclear fusion reactors, designing chemical compounds, and detecting eye diseases. Games offer a diverse range of challenges and allow for rapid experimentation, making them ideal platforms for developing and testing AI algorithms. Virtual simulations in games are more convenient for AI development compared to robotics.
The DQN agent system, tested on Atari games in 2013 with raw pixels as its only input, successfully learned to play Breakout, improving over time as it gained experience. The goal of reinforcement learning is to develop a single system that can play all different games out of the box. The DQN agent system demonstrated this potential by learning to play Breakout, a seminal game on the Atari system.
Creativity and Intuition in AI
Hassabis discusses the essence of creativity and intuition in AI, drawing a distinction between rule-based creativity and genuine invention. While current AI systems excel at tasks involving statistical averaging and pattern recognition, they struggle with tasks requiring abstract thinking and imagination. Hassabis points to the hippocampus’s role in imagination, suggesting that understanding human brain mechanisms can inspire more creative AI systems.
In Go, originality and creativity are judged by the effectiveness of a move, which is determined by the outcome of the game. AlphaGo’s move 37 in its match with Lee Sedol was initially considered a mistake by expert commentators, but later analysis revealed it to be an effective and creative move. AlphaGo’s approach to the game was distinct from traditional Go strategies used by professionals. In game two, AlphaGo made a surprising move (move 37) by placing a stone on the fifth line early in the game, which is unconventional and considered suboptimal.

Imagination tasks were tested on patients with damaged hippocampus, and their descriptions of imagined scenarios were significantly impoverished. A graph shows the difference in richness between patients and control subjects.
Challenges in AI Development
Despite its advancements, AI faces several challenges. The need for explainability and interpretability in AI systems is critical for their safe and ethical application. Hassabis advocates for human involvement in AI-driven decision-making processes. Additionally, the speed of AI research has led to an over-promising hype cycle, necessitating a more measured approach to development and empirical testing.
Artificial Intelligence: A Meta Solution for the Modern World
AI, as Hassabis outlines, offers solutions to the complexities and information overload of modern systems. It transforms unstructured data into actionable knowledge, aiding in the understanding of intricate systems. However, this potential comes with responsibilities, emphasizing the need for safe AI use and ensuring its benefits are widely accessible.
