A list of topics for a Google summer of code (GSOC) 2011

Online learning

Mentor : O. Grisel

Goal : Devise an intuitive yet efficient API dedicated to the incremental fitting of some scikit-learn estimators (on an infinite stream of samples for instance).

See this thread on the mailing list for a discussion of such an API. Design decision will be taken by implementing / adapting three concrete models:

• text feature extraction
• online clustering with sequential k-means
• generalized linear model fitting with Stochastic Gradient Descent (both for regression and classification)
