Model was trained on MNIST dataset containing 60000 training images and 10000 test images.

The model is a convolutional neural network (CNN) consisting of 6 layers.

Conv2d(input_channels,output_channels,kernel_size,padding,stride)
tConv2d(input_channels,output_channels,kernel_size,padding,stride,output-padding)

Layer 1: Conv2d(1,32,3,p=1,s=2)
Layer 2: Conv2d(32,64,3,p=1,s=2) 
Layer 3: Conv2d(64,128,5) 

Layer 4: tConv2d(128,64,5) 
Layer 5: tConv2d(64,32,3,p=1,s=2,op=1) 
Layer 6: tConv2d(32,1,3,p=1,s=2,op=1) 

Gaussian noise was added via torch.randn() with a tunable noise factor variable.

def add_noise(inputs,noise_factor=0.3):  
  noisy = inputs + (torch.randn_like(inputs) * noise_factor)  
  noisy = torch.clip(noisy,0.,1.)  
  return noisy
