Disturbing Target Values for Neural Network regularization: attacking the loss layer to prevent overfitting

Overview

Disturbing Target Values for Neural Network regularization: attacking the loss layer to prevent overfitting

1. Classification Task

PyTorch implementation of DisturbLabel: Regularizing CNN on the Loss Layer [CVPR 2016] extended with Directional DisturbLabel method.

This classification code is built on top of https://github.com/amirhfarzaneh/disturblabel-pytorch/blob/master/README.md project and utilizes implementation from ResNet 18 from https://github.com/huyvnphan/PyTorch_CIFAR10

Directional DisturbLabel

  if args.mode == 'ddl' or args.mode == 'ddldr':
      out = F.softmax(output, dim=1)
      norm = torch.norm(out, dim=1)
      out = out / norm[:, None]
      idx = []
      for i in range(len(out)):
          if out[i,target[i]] > .5:
              idx.append(i)
              
      if len(idx) > 0:
          target[idx] = disturb(target[idx]).to(device)

2. Regression Task

DisturbValue

def noise_generator(x, alpha):
    noise = torch.normal(0, 1e-8, size=(len(x), 1))
    noise[torch.randint(0, len(x), (int(len(x)*(1-alpha)),))] = 0

    return noise

DisturbError

def disturberror(outputs, values):
    epsilon = 1e-8
    e = values - outputs
    for i in range(len(e)):
        if (e[i] < epsilon) & (e[i] >= 0):
            values[i] = values[i] + e[i] / 4
        elif (e[i] > -epsilon) & (e[i] < 0):
            values[i] = values[i] - e[i] / 4

    return values
