Study Notes
Artificial Intelligence
- AI involves solving problems using intelligent agents that interact with environments
- Rationality is a key aspect of intelligent agents, which strive to make optimal decisions
Agents and Environments
- Agents perceive and act upon environments, which can be fully or partially observable
- Environments can be deterministic or stochastic, and can be affected by the agent's actions
- Agents can be simple reflex agents, model-based reflex agents, or goal-based agents
Problem Solving Agents
- Problem solving agents use various strategies to achieve goals, including planning and problem formulation
- Planning involves decomposition of tasks into sub-tasks and execution of plans
- Classical planning problems involve finding a sequence of actions to achieve a goal
Searching and Game Theory
- Searching involves finding a path to a goal state, which can be done using uninformed and informed search strategies
- Uninformed search strategies include BFS, DFS, and UCS
- Informed search strategies include Greedy Best First Search and A* Search
- Adversarial search involves finding the best move in a game, using algorithms like Minimax and Alpha-Beta pruning
- Evaluation functions are used to estimate the value of a game state
Knowledge Representation and Reasoning
- Logical agents reason using propositional and first-order logic
- Knowledge-based agents use knowledge representation schemes, such as semantic networks and frames
- Wumpus world is a classic example of a knowledge-based agent
- Propositional logic involves AND, OR, and NOT operators, and resolution patterns
- First-order logic involves predicates and quantifiers, and can be used for inference
Uncertain Knowledge and Reasoning
- Bayes' rule is used to update probabilities based on new evidence
- Time and uncertainty are key aspects of decision-making under uncertainty
- Utility functions are used to quantify preferences and make decisions
- Markov decision processes (MDPs) involve making decisions in partially observable environments
- Value iteration and policy iteration are algorithms for solving MDPs
