Online/Batch generalized linear models under square loss 1.0 Description 

Description: This is the package for online (competitive)/batch prediction using generalized linear models under square loss. The algorithms are derived using the Aggregating Algorithm.
The algorithms have guarantees on the cumulative square loss for the worst case when applied in online fashion in comparison with the best model from the class [1].
The variable regressed should lie in [0,1], thus the program is a tool for twoclass classification or for bounded regression. Four possibilities are provided: linear regression, logistic regression, probit regression, comlog regression. Other functions can be easily added/used.
The models are developed and first applied in [1], the competitor to linear regressor (AAR) was first suggested in [2].
FIle examplepredict.m contains an example of use. The data set is the wine data set available from UCI Machine Learning Repository. Two first clases are taken, vectors are randomly permuted, features are normalized to have zero mean and maximum absolute value 1. This particular problem is not very suitable for online regression, so the data set just illustrates how to use the program.

Optimal experimental designs for generalized linear models (GLM) depend on the unknown coefficients, and two experiments having the same model but different coefficient values will typically have different optimal designs. Therefore, unlike experimental design for linear models, the prior knowledge and estimates of the outcome of an experiment must be taken into account.
