ReLUs 1.0.1

A Python package for direct implementation of ReLU network.

ReLU neural network

rectified linear activation function

What is ReLU ?

ReLU is defined as g(x) = max(0,x). It is 0 when x is negative and equal to x when positive. Due to it’s lower saturation region, it is highly trainable and decreases the cost function far more quickly than sigmoid.

install

pip install ReLUs

or

pip3 install ReLUs

parameters for the model to train

layers_sizes   (e.g.  layers_size=[13,5,5,1])
num_iters      (e.g. num_iters=1000)
learning_rate (e.g. learning_rate=0.03)

training the model

model_name =  model(X_train, Y_train, layer_sizes, num_iters, learning_rate)

train and test accuracy

train_acc, test_acc = compute_accuracy(X_train, X_test, Y_train, Y_test, model_name)

making predictions

predict(X_train,your_model)
