Introduction

This repo is a Nerual Network Framework for learning Deep-Learning and Machine-Learning.

This framework refers to PyTorch's Design and Usage.

Usage

```python import nnplayer as npl import numpy as np

build net

net = npl.Sequence(npl.Linear(10, 6), npl.Sigmoid(), npl.Linear(6, 4), npl.Sigmoid())

calculate loss

loss = npl.MSELoss(net)

optimizer

optimizer = npl.SGD(net.getParamsList())

build the dataset

X = np.arange(40).reshape(4, 10) Y = np.arange(16).reshape(4, 4)

train

epoch = 100 for i in range(epoch): Ypredict = net.forward(X) l = loss.loss(Ypredict, Y) print(f'epoch{i + 1} loss:{l.mean()}') loss.backward() optimizer.step() l = loss.loss(net.forward(X), Y) print(l.mean()) ```
