Fixing Bias in Reconstruction-based Anomaly Detection with Lipschitz Discriminators

Anomaly detection is of great interest in fields where abnormalities need to be identified and corrected (e.g., medicine and finance). Deep learning methods for this task often rely on autoencoder reconstruction error, sometimes in conjunction with …

TrajectoryNet: A Dynamic Optimal Transport Network for Modeling Cellular Dynamics

A Combination of Continuous Normalizing Flows and Dynamic Optimal Transport to model the dynamics of cells.

Interpretable Neuron Structuring with Graph Spectral Regularization

While neural networks are powerful approximators used to classify or embed data into lower dimensional spaces, they are often regarded as black boxes with uninterpretable features. Here we propose Graph Spectral Regularization for making hidden …

Finding Archetypal Spaces Using Neural Networks

Archetypal analysis is a data decomposition method that describes each observation in a dataset as a convex combination of ''pure types'' or archetypes. These archetypes represent extrema of a data space in which there is a trade-off between …

Allocate-On-Use Space Complexity of Shared-Memory Algorithms

Many fundamental problems in shared-memory distributed computing, including mutual exclusion [8], consensus [18], and implementations of many sequential objects [14], are known to require linear space in the worst case. However, these lower bounds …
