Features

1. Nano-AutoGrad offers the following features:

   • Automatic Differentiation: Nano-AutoGrad automatically * computes gradients, making it easy to perform gradient-based optimization.
   • Computational Graph Engine: It leverages a computational graph representation to efficiently compute gradients and perform backpropagation.
   • Lightweight and Efficient: Nano-AutoGrad is designed to be lightweight and efficient, suitable for small to medium-sized neural networks.
   • Easy-to-Use API: The framework provides a simple and intuitive API, allowing users to define and train neural networks with ease.
   • Integration with NumPy: Nano-AutoGrad seamlessly integrates with NumPy, enabling efficient array operations and computations.

Usage

To get started with Nano-AutoGrad, refer to the documentation for detailed usage instructions, examples, and API reference. Here are some basic steps to build and train a neural network using Nano-AutoGrad:

• examples 1 :

   import numpy as np
   import autograd.core.nn as nn
   import autograd.torch.optim as nn
  
   class MyNeuralNetwork(na.Module):
       def __init__(self):
           self.linear = na.Linear(2, 1)
  
       def forward(self, x):
           return self.linear(x)
  
   network = MyNeuralNetwork()
   optimizer = na.SGD(network.parameters(), lr=0.1)
  
  

• Example 2 : building ‘Linear Model’ using torch autograd engine

  
    import autograd.torch.nn as nn 
    import autograd.torch.tensor as Tensor
    import autograd.torch.optim as SGD
    import autograd.functiona as F
  
    class Model(nn.Module):
        def __init__(self):
            super().__init__()
            self.l1 = nn.Linear(784, 1568, name='l1')
            self.l2 = nn.Linear(1568, 392, name='l2')
            self.l3 = nn.Linear(392, 10, name='l3')
  
        def forward(self, x):
            z = F.relu(self.l1(x))
            z = F.relu(self.l2(z))
            out = F.log_softmax(self.l3(z))
            return out
  
    model = Model()
    optimizer = autograd.optim.SGD(model.parameters(), lr=5e-2, weight_decay=1e-4)
    scheduler = autograd.optim.lr_scheduler.LinearLR(optimizer, start_factor=1.0, end_factor=0.75, total_iters=num_epochs)
