Text Classification/Categorization. Evaluating classification techniques. Using classifiers as basis for retrieval (aka relevance feedback). Distance-based classification strategies--Rochchio, k-nearest neighbors. Their relative advantages/disadvantages. (Aside on LDA--linear discriminant analysis and LSI as a special case of LDA where each element is its own class). Why distance-based methods are not enough. Learning as pattern-finding. Multiple pattern languages (biases) and their relative tradeoffs.
