Module src.models

Classes

class FNN (p)

Base class for all neural network modules.

Your models should also subclass this class.

Modules can also contain other Modules, allowing to nest them in a tree structure. You can assign the submodules as regular attributes::

import torch.nn as nn
import torch.nn.functional as F

class Model(nn.Module):
    def __init__(self):
        super(Model, self).__init__()
        self.conv1 = nn.Conv2d(1, 20, 5)
        self.conv2 = nn.Conv2d(20, 20, 5)

    def forward(self, x):
        x = F.relu(self.conv1(x))
        return F.relu(self.conv2(x))

Submodules assigned in this way will be registered, and will have their parameters converted too when you call :meth:to, etc.

Initializes internal Module state, shared by both nn.Module and ScriptModule.

    def __init__(self, p):
        super(FNN, self).__init__()
        self.fc1 = nn.Linear(p, 100)
        self.relu1 = nn.ReLU()
        self.fc2 = nn.Linear(100, 2)
        self.use_softmax = True

    def forward(self, x):
        x = self.fc1(x)
        x = self.relu1(x)
        x = self.fc2(x)
        if self.use_softmax:
            x = F.softmax(x, dim=1)
        return x

Methods

def forward(self, x)

Defines the computation performed at every call.

Should be overridden by all subclasses.

Note

Although the recipe for forward pass needs to be defined within this function, one should call the :class:Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
