Topics covered in the Workshop
- Introduction : Definition of learning systems. Goals and applications of machine learning. Aspects of developing a learning system: training data, concept representation, function approximation.
- Inductive Classification : The concept learning task. Concept learning as search through a hypothesis space. General-to-specific ordering of hypotheses.
- Decision Tree Learning: Representing concepts as decision trees. Recursive induction of decision trees. Picking the best splitting attribute: entropy and information gain. Searching for simple trees and computational complexity. Occam’s razor. Over fitting, noisy data, and pruning.
- Ensemble Learning :Using committees of multiple hypotheses. Bagging, boosting, and DECORATE. Active learning with ensembles.
- Experimental Evaluation of Learning Algorithms: Measuring the accuracy of learned hypotheses. Comparing learning algorithms: cross-validation, learning curves, and statistical hypothesis testing.
