      • Speech recognition
      • Playing games like chess or Go
      • Machine translation
      • Web searches

    What Can People Do That Computers Can't Do?

    • CAPTCHA: A program designed to tell apart humans from computers (e.g., reading distorted text)

    Thinking Rationally

    • Rational thinking involves using logic and reason to solve problems.
    • Aristotle's Syllogism: A form of deductive reasoning, for example, "Socrates is a man, all men are mortal, therefore Socrates is mortal."

    Acting Rationally

    • Rational behavior aims to achieve the best possible outcome, given the available information and goals.
    • Rational agents make the best possible decisions based on the available data.
    • This often involves uncertainty and dealing with complexity.

    Rational Decisions

    • Rationality in AI focuses on the decisions made, not the thought process behind them.
    • Goals are expressed in terms of outcomes (utility).
    • The best decisions maximize expected utility.

    A Short History of AI

    • The idea of AI dates back to ancient Greek philosophers.
    • Recent advancements in AI are driven by specific hardware and software.

      • Deep Blue vs. Kasparov matches (1990s)
      • AlphaGo (defeating top human Go players)

    DeepMind (Google Deep Learning)

    • DeepMind is a leading AI research organization, focusing on deep learning.

    Embedded Applications

    • AI underpins many useful systems, providing support for tasks such as:
      • Scheduling, e.g., airline routing
      • Route planning, e.g., Google Maps
      • Medical diagnostics, e.g., EKG analysis
      • Automated surveillance
      • Web search engines
      • Spam classifiers

    Future of AI

    • Progress is accelerating in AI.
    • Benefits are valuable and will grow as AI improves.
    • The development of AI will bring significant changes and opportunities.

    What If We Do Succeed?

    • Successful AI development could have profound positive impacts, but potential risks exist

    Reasons Not to Worry

    • Concerns relating to AI reaching human intelligence levels are often overstated or not well considered.
    • AI is a tool people control, not the other way around.

    So, If That Matters...

    • What are the possible paths for AI evolution (best and worst-case scenarios)?
    • Can AI development be guided to avoid potential risks?

    Artificial Intelligence Problem Solving - Uninformed Search

    • Algorithms for AI problem-solving that don't use any prior knowledge.
    • Includes Depth-First, Breadth-First, and Uniform-Cost searches.

    Agents that Plan Ahead

    • Planning agents make decisions based on predicted consequences.
    • They need a model of how the world reacts to actions.
    • Agents usually want to find a goal.

    Search Problems

    • Search problems involve finding solutions in a state space, using resources such as actions and costs.
    • A solution is a sequence of actions that leads from the start state to the goal state.

    Search Gone Wrong

    • Example scenarios/illustrations of search algorithm failures
