Code Released: Confidence-Calibrated Adversarial Training

The code for my latest paper on confidence-calibrated adversarial training has been released on GitHub. The repository does not only include a PyTorch implementation of confidence-calibrated adversarial training, but also several white- and black box attacks to generate adversarial examples and the proposed confidence-thresholded robust test error. Furthermore, these implementations are fully tested and allow to reproduce the results from the paper. This article gives an overview of the repository and highlights its features and components.

FONTS: A Synthetic MNIST-Like Dataset with Known Manifold

In deep learning and computer vision, data is often assumed to lie on a low-dimensional manifold, embedded within the potentially high-dimensional input space — as, for example, for images. However, the manifold is usually not known which hinders deeper understanding of many phenomena in deep learning, such as adversarial examples. Based on my recent CVPR’19 paper, I want to present FONTS, a MNIST-like, synthetically created dataset with known manifold to study adversarial example.

A Note on Extending Tensorflow, PyTorch, Theano and Torch for Deep Learning on Custom Data Structures

Many recent deep learning frameworks such as Tensorflow, PyTorch, Theano or Torch are based on dense tensors. However, deep learning on non-tensor data structures is also interesting – especially for sparse, three-dimensional data. This article summarizes some of my experiences regarding deep learning on custom data structures in the mentioned libraries.
