    Study Notes

    Supervised Learning

    • Type of machine learning where the algorithm learns from labeled data
    • Goal: learn a mapping between input data and output labels
    • Training data consists of input-output pairs $(x, y)$
    • Algorithm learns to predict output $y$ for new, unseen input $x$

    Classification

    • Type of supervised learning problem where the output is categorical
    • Goal: predict a class label or category that an instance belongs to
    • Examples:
      • Spam vs. not spam emails
      • Cancer diagnosis (malignant vs. benign)
      • Handwritten digit recognition (0-9)
    • Key concepts:
      • Classes: distinct categories or labels
      • Features: characteristics or attributes of the data
      • Decision boundary: boundary that separates classes in feature space

    Classification Algorithms

    • Logistic Regression:
      • Uses logistic function to model probability of class membership
      • Linear decision boundary
    • Decision Trees:
      • Hierarchical representation of decisions
      • Classify instances by traversing the tree
    • Random Forest:
      • Ensemble of decision trees
      • Improved accuracy and robustness
    • Support Vector Machines (SVMs):
      • Find hyperplane that maximally separates classes
      • Can be kernelized for non-linear boundaries
