Distributed Gossip training for Fashion MNIST classification

photo by xiandong79

This Project is a Pytorch Implementation of a paper entitled “Gossip training for deep learning” by Michael Blot et al which proposed a distributed method for training deep learning networks.

I’ve used the Gossip training method for a multilabel classification task

Dataset

For implementing gossip training I chose fashion MNIST for training and evaluation of networks. Images of this dataset are gray-level images in 10 classes as described below:
0: T-shirt/top, 1: Trouser, 2: Pullover, 3: Dress, 4: Coat, 5: Sandal, 6: Shirt, 7: Sneaker, 8: Bag, 9: Ankle boot

As a preprocessing step, before Training the networks I normalized the images.

Training

I’ve implemented different Configurations of Gossip training to investigate the role of probability parameters, Communication matrix, and the kind of communication graph.
different models are listed below:

  • centralized model
  • Gossip training
    • Gossip training for different values of parameter p as the probability of communication
    • Gossip training for different communication matrices
      • Random Matrix
      • Double Random Matix
      • The matrix variates with time
    • Gossip training for Different Communication graphs
      • strongly connected
      • periodically strongly connected

Below you can see loss and accuracy during training for different amounts of parameter p:

Results

Results for different values of parameter p are in the below table

Parameter p Accuracy%
1 87,14
0.5 87,29
0.2 87,25
0.1 86,45

Results for different Communication matrices are as below

communication matrix Accuracy%
Random 90,98
Double Random 90,56
Varying with time 86,94

Results for different Communication graphs are as below

communication graph Accuracy%
Periodically strongly connected 89,18
Strongly connected 89,81
