step-wise fit
random forest (RF)
artificial neural networks (ANN)
ELM

>>Feature selection
Correlation coefficients, Fisher ratio
minimum redundancy maximal relevance (mRMR)
single feature predictor
sequential forward selection (SFS)
genetic algorithm (GA)
random forest (RF)
step-wise fit
AdaBoost
SVM-RFE (original linear and kernel version)

>>Representative sample selection (active learning)
Cluster centers
transductive experimental design (TED)

* Unified and simple interface;
* Convenient to observe and change algorithm parameters
* Extensible. Simple file structures makes it easier to modify the algorithms.

***Interfaces***

>>Feature processing
[Xnew, model] = ftProc_xxx_tr(X,Y,param) % training
Xnew = ftProc_xxx_te(model,X) % test

>>Classification
model = classf_xxx_tr(X,Y,param) % training
[pred,prob] = classf_xxx_te(model,Xtest) % test, return the predicted labels and probabilities (optional)

>>Regression
model = regress_xxx_tr(X,Y,param) % training
rv = regress_xxx_te(model,Xtest) % test, return the predicted values

>>Feature selection
[ftRank,ftScore] = ftSel_xxx(ft,target,param) % return the feature rank (or subset) and scores (optional)

>>Representative sample selection (active learning)
smpList = smpSel_xxx(X,nSel,param) % return the indices of the selected samples

Please see test.m for sample usages.

Besides, there are three uniform wrappers: ftProc_, classf_, regress_. They accept algorithm name strings as inputs and combine the training and test phase.
