    Study Notes

    Natural Language Processing (NLP)

    • NLP is a branch of AI focusing on the interaction between computers and humans through natural language
    • Facilitates machines understanding and generating human language
    • NLP involves understanding, interpretation, and generation of language
    • Key tasks include language translation, text summarization, and speech recognition
    • NLP breaks down language into comprehensible units, infers meaning and context, and crafts natural language responses

    Natural Language Understanding (NLU)

    • NLU is a subset of NLP, focusing on comprehending human language
    • Enables machines to grasp the meaning and context of language inputs
    • NLU involves comprehension, contextual interpretation, and sentiment analysis
    • Key tasks include entity recognition, intent detection, and contextual relevance
    • NLU analyzes language for meaning, understands the context, and determines the emotional tone

    Natural Language Generation (NLG)

    • NLG is a branch of NLP focused on generating human-like language from data
    • Transforms structured information into readable text or speech
    • NLG involves data analysis, content planning, and text realization
    • Key tasks include report generation, automated journalism, and conversational agents
    • NLG interprets and organizes data, structures narratives, and converts data into coherent language

    Agent and Environment in AI

    • An AI system is composed of an agent and its environment
    • The agent acts within the environment, which may contain other agents
    • An agent is anything that perceives its environment through sensors and acts on it through effectors
    • Agents use actuators for perception, thought, and action

    Types of Agents

    • Human agents have sensory organs (eyes, ears) as sensors and body parts (hands, legs) as actuators
    • Robotic agents have cameras and infrared range finders as sensors and servos and motors as actuators
    • Software agents have file contents, keystrokes, and network packages as sensors and output on a screen as actuators

    Environment in AI

    • An environment is everything surrounding the agent but not part of the agent itself
    • Fully observable environments provide the AI with complete information about its surroundings, allowing informed decisions
    • Partially observable environments limit the AI's information, requiring decisions based on limited data
    • Deterministic environments have predictable outcomes based on initial conditions and actions taken
    • Stochastic environments have uncertain outcomes due to random or unpredictable factors

    Intelligent Agents in AI

    • Intelligent agents in AI are autonomous entities that act in an environment using sensors and actuators to achieve goals
    • They may learn from the environment to achieve those goals
    • Driverless cars and virtual assistants are examples of intelligent agents
    • AI agents must adhere to four rules: perception, decision-making, action, and rational action, maximizing performance and positive outcomes

    Natural Language Processing (NLP)

    • Branch of AI focused on interaction between computers and humans using natural language
    • Facilitates understanding and generating human language
    • Core Functions:
      • Understanding: decomposing language into comprehensible units
      • Interpretation: inferring meaning and context
      • Generation: crafting responses in natural language
    • Key Tasks:
      • Language translation: maintaining semantic integrity across languages
      • Text summarization: condensing extensive text to key points
      • Speech recognition: converting spoken words to text
    • How NLP Works:
      • Scenario: User asks "What’s the weather like today in New York City?"
      • Process:
        • Tokenization: sentence is broken down into individual words or tokens
        • Part-of-Speech Tagging: assigns a part of speech to each word
        • Named Entity Recognition (NER): identifies and classifies named entities, e.g. "New York City"
        • Intent Recognition: determines user intent from structure and recognized entities
        • Response Generation: crafts a response aligned with recognized intent

    Natural Language Understanding (NLU)

    • Subset of NLP focusing on comprehending human language
    • Enables machines to grasp meaning and context of language inputs
    • Core Functions:
      • Comprehension: analyzing language for meaning
      • Contextual Interpretation: understanding context in which words are used
      • Sentiment Analysis: determining emotional tone behind words
    • Key Tasks:
      • Entity Recognition: identifying and classifying key elements in text
      • Intent Detection: understanding the purpose of a user's input
      • Contextual Relevance: assessing language significance in context
    • Example:
      • A customer service chatbot for a travel agency
      • User interaction: "I want to book a flight to Paris next Friday, but I'm not sure about the return date."

    Agents and Environments in AI

    • AI system is composed of an agent and its environment
    • Agents act in their environment
    • Agent is anything that can perceive its environment through sensors and act on it through actuators

    Types of Agents

        • Example: Factory robot
      • Incomplete: AI lacks some critical information
        • Example: Robot vacuum cleaner
      • Static: environment’s state does not change unless the AI acts
        • Example: Puzzle-solving AI
      • Dynamic: environment changes with or without AI actions
        • Example: Self-driving car
      • Known: AI has prior experience or knowledge
        • Example: AI navigating a familiar environment
      • Unknown: AI has no prior knowledge of the environment

    • Autonomous entities that act upon an environment using sensors and actuators to achieve goals
    • Rules:
      • Rule 1: Must be able to perceive the environment.
      • Rule 2: Observations must be used to make decisions.
      • Rule 3: Decisions should result in action.
