CapsNet-CNTK

A CNTK implementation of CapsNet based on the paper titled 'Dynamic Routing Between Capsules' by Sara Sabour, Nicholas Frost and Geoffrey Hinton.

Requeriments

• Python >=3.5
• CNTK 2.4
• Tensorboard (optional)

Architecture

Training

git clone https://github.com/southworkscom/CapsNet-CNTK.git
cd CapsNet-CNTK
python get_data.py
python main.py

Tensorboard

Visualize training progress with tensorboard:

tensorboard --logdir tensorboard

Then, Open your favorite browser and navigate to http://localhost:6006 (assuming you are running the training at localhost)
