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
