    Study Notes

    Artificial Intelligence (AI)

    • Definition: AI refers to the simulation of human intelligence in machines that are programmed to think and learn.

    Machine Learning (ML)

    • Definition: A subset of AI that enables systems to learn from data and improve performance over time without being explicitly programmed.
    • Types:
      • Supervised Learning: Uses labeled data to train models (e.g., classification, regression).
      • Unsupervised Learning: Finds patterns or groupings in unlabeled data (e.g., clustering).
      • Reinforcement Learning: Agents learn to make decisions by receiving rewards or penalties.
    • Key Algorithms:
      • Linear Regression
      • Decision Trees
      • Support Vector Machines
      • Neural Networks

    Natural Language Processing (NLP)

    • Definition: A branch of AI focused on the interaction between computers and humans through natural language.
    • Applications:
      • Text analysis (sentiment analysis, topic modeling)
      • Machine translation (e.g., Google Translate)
      • Chatbots and virtual assistants (e.g., Siri, Alexa)
    • Techniques:
      • Tokenization: Breaking text into words/phrases.
      • Named Entity Recognition (NER): Identifying proper nouns in text.
      • Language Modeling: Predicting word sequences.

    Computer Vision

    • Definition: A field of AI that enables computers to interpret and process visual information from the world.
    • Applications:

      • Autonomous vehicles (e.g., recognizing road signs, detecting obstacles)
      • Medical imaging analysis (e.g., detecting tumors in scans)
    • Techniques:
      • Convolutional Neural Networks (CNNs): For processing grid-like data such as images.
      • Image segmentation: Dividing an image into segments for easier analysis.
      • Optical Character Recognition (OCR): Converting images of text into machine-readable text.

    AI Ethics

    • Definition: The field that examines the moral implications and societal impact of AI technologies.
    • Key Considerations:
      • Bias: Addressing biases in AI algorithms which may lead to unfair treatment.
