Matrix Capsules with EM Routing

A PyTorch implementation of Matrix Capsules with EM Routing

Usage

1. Install PyTorch

2. Start training (default: CIFAR-10)

python train.py --batch-size 20 --test-batch-size 20

CIFAR-10 experiments

The experiments are conducted on Tesla K80 Specific setting is lr=0.01, batch_size=20, weight_decay=0, Adam optimizer, without data augmentation.

Following is the result after training:

Arch	EM-Iters	Coord Add	Loss	Epochs	Test Accuracy
