Flexible SVM framework implementation

SVM_Framework

Support vector machines flexible framework
We solve the unconstrained primal SVM formulation
SVM & Softmax classifiers supported
NB:
-Softmax classifier refers to penalized and kernalized logistic regression
-Classical logistic regression can be obtained by setting cost very high & using a linear kernel
-R implementation in a seperate repository

1. Classifiers/regressors:

LS: regression classifier using penalized least squared loss
Softmax: Softmax classifier using cross entropy loss
SVM:svm classifier using quadratic hinge loss

2. Optimization methods:

BGD: gradient descent (batch)
NGD: Newton-Raphson optimization (batch)
CGD: conjugate gradient descent (batch)
SGD: stochastic gradient descent (under development)

3. Kernels:

gaussian: gaussian kernel
linear: linear kernel
poly:polynomial kernel
