Class Format

all class can be used in this way:(LR for example)

but there is still some different Initialization parameters in different class,also the predict function

sorry for this but most class use pred() and NN use nnpred(),I may formalize them in the future

a = LRC(train_images,trian_labels,nor=False)
a.train(200,True)
pred = a.predict(test_images)

for the input X and y ,X must be a N*M matrix and y is a vector length M

where N is the #feature and M is #training_case

for the cluster method,you can use a.labels or a.result() to get the final result

---

Install

DML is based on numpy,scipy,matplotlib .you should install them first

This packages uses setuptools, which is the default way of installing python modules. The install command is:(sudo is required in some system)

python setup.py build
python setup.py install

---

Warning

• only python 2 is supported,sorry for the python 3 user.

• some method from numpy and scipy will report warning because of their version
