    Study Notes

    Artificial Intelligence (AI)

    • AI refers to machine intelligence, particularly in computer systems.
    • It's a field studying methods and software for machines to sense, learn, and act to achieve goals.
    • High-profile AI applications include web search, recommendations, virtual assistants, autonomous vehicles, and creative tools.

    Goals of AI Research

    • Key goals include reasoning, knowledge representation, planning, learning, natural language processing (NLP), perception, and robotics support.
    • A long-term goal is creating general intelligence (performing any human task at an equal level or better).
    • Techniques include search, optimization, logic, neural networks, statistics, operations research, and economics.

    Reasoning and Problem-Solving

    • Early AI focused on mimicking human logical steps in solving problems.
    • Later methods addressed uncertainty and incomplete information using probability and economics.
    • Large reasoning problems are challenging due to combinatorial explosion (exponential growth in difficulty).
    • Humans often use intuitive judgments, which are currently not readily modeled computationally.

    Knowledge Representation

    • Ontologies represent knowledge as concepts and their relationships within a domain.
    • Knowledge bases store knowledge in a useable format for AI programs for content-based indexing.
    • Knowledge acquisition is crucial but difficult (obtaining knowledge required for AI).
    • Commonsense knowledge is vast and sub-symbolic (not expressed as "facts").

    Planning and Decision-Making

    • Agents are entities that perceive and act in the world.
    • Rational agents aim to achieve goals, considering probabilities and utilities of possible outcomes.
    • Classical planning assumes exact actions, whereas real-world planning involves uncertainty.
    • Markov decision processes model planning with uncertainty in the environment and rewards.

    Learning

    • Machine learning automatically improves performance on tasks.
    • Types include:
      • Unsupervised learning: finds patterns in data without guidance.
      • Supervised learning: learns from labeled data (classification and regression).
      • Reinforcement learning: learns through rewards and punishments.
      • Transfer learning: applies knowledge from one task to another.
      • Deep learning: uses artificial neural networks for various learning types.

    Natural Language Processing (NLP)

    • NLP enables machines to understand and generate human language.
    • Related tasks include speech recognition, synthesis, translation, and information retrieval.
    • Modern methods use word embeddings, transformers, and large language models (LLMs).

    Perception

    • Machine perception uses sensors to understand the environment.
    • Computer vision is a crucial part, focused on analyzing visual information.
    • Tasks include image/speech recognition, object recognition, object tracking, and robotic perception.

    Social Intelligence

    • Affective computing is about understanding and responding to human emotions.
    • Some virtual assistants show rudimentary emotional responses.
    • This area is challenging and often misinterprets users' emotional states.

    Techniques

    • Search and Optimization: Finding solutions by searching through many possible options.
      • State space search: Exploring trees of potential states for goals.
      • Local search: Refining an initial guess to find an optimal solution.
      • Examples: Gradient descent, evolutionary computation, swarm intelligence.
    • Logic: Formal logic is used for reasoning, including propositional and predicate logic.
    • Probabilistic Methods: Handle uncertainty in many AI problems.
      • Bayesian networks
      • Hidden Markov models

    Artificial Neural Networks (ANNs)

    • ANNs are networks of interconnected nodes modeling biological neurons.
    • They learn to recognize patterns and relationships between inputs and outputs through training (typically using gradient descent).
    • Types include feedforward, recurrent, convolutional, and deep neural networks.

    Deep Learning

    • Deep learning uses multiple layers of neurons to extract hierarchical features from data.
    • Improvements in computer power and data availability have led to its success in various AI fields (e.g., computer vision, NLP).
    • Generative pre-trained transformers (GPTs) are large language models trained on massive text datasets (for example, ChatGPT).

    Hardware and Software

    • GPUs and specialized AI software have become dominant for training large-scale machine learning models, replacing CPUs.
    • General-purpose programming languages like Python are now prevalent, compared to older languages like Prolog.

    AI Applications

    • AI is used across various sectors, including healthcare, finance, games, and military applications.
    • AI applications include search engines, advertisements, virtual assistants, and autonomous vehicles.

    Ethics of AI

    • AI has potential benefits and risks, including privacy concerns, biased algorithms, and potential misuse.
    • Techniques for preserving privacy exist (e.g., data aggregation), but major concerns remain.
    • AI safety and ethical guidelines are active areas of research and discussion.

    Risks and Harms

    • Privacy: AI systems collect vast amounts of personal data, raising privacy concerns.
    • Copyright: Generative AI sometimes uses copyrighted materials without permission.
    • Dominance by Big Tech: Domination by large tech companies can cause market issues and centralization.
    • Power use and environmental effects: AI systems consume significant amounts of electrical energy.
    • Misinformation: AI can be used to create and spread false information.
    • Algorithmic bias and fairness: AI systems can inherit biases from the data they're trained on, potentially leading to discrimination.
    • Lack of transparency: Complex AI systems can be difficult to understand how they make decisions.

    Other

    • Many other specific applications of AI in various industries exist and are constantly evolving.
    • The long-term implications of AI remain a subject of debate among scientists, ethicists, and policymakers.
