Feature Visualization

How neural networks build up their understanding of images. Feature visualization allows us to see how GoogLeNet, trained on the ImageNet dataset, builds up its understanding of images over many layers. Visualizations of all channel are available in the appendix.

How to Use t-SNE Effectively

Although extremely useful for visualizing high-dimensional data, t-SNE plots can sometimes be mysterious or misleading. By exploring how it behaves in simple cases, we can learn to use it more effectively.

Seminar Talk on Model Compression

I recently gave a seminar talk on model compression in Machine Learning. It gives an overview of different techniques developed to compress the final model obtained after training in order to reduce memory footprint and speed–up prediction. I covered pruning methods such as Optimal Brain Damage (OBD) and Optimal ...
