Differentiable Clustering with Perturbed Spanning Forests

NeurIPS 2023poster

We introduce a differentiable clustering method based on stochastic perturbations of minimum-weight spanning forests. This allows us to include clustering in end-to-end trainable pipelines, with efficient gradients. We show that our method performs well even in difficult settings, such as data sets…

Regression as Classification: Influence of Task Formulation on Neural Network Features

AISTATS 2023poster

Neural networks can be trained to solve regression problems by using gradient-based methods to minimize the square loss. However, practitioners often prefer to reformulate regression as a classification problem, observing that training on the cross entropy loss results in better performance. By focu…
