Spot the Difference: Detection of Topological Changes via Geometric Alignment

NeurIPS 2021poster

Geometric alignment appears in a variety of applications, ranging from domain adaptation, optimal transport, and normalizing flows in machine learning; optical flow and learned augmentation in computer vision and deformable registration within biomedical imaging. A recurring challenge is the alignme…

A Loss Function for Generative Neural Networks Based on Watson’s Perceptual Model

NeurIPS 2020poster

To train Variational Autoencoders (VAEs) to generate realistic imagery requires a loss function that reflects human perception of image similarity. We propose such a loss function based on Watson's perceptual model, which computes a weighted distance in frequency space and accounts for luminance an…

Algorithms for Estimating the Partition Function of Restricted Boltzmann Machines (Extended Abstract)

IJCAI 2020poster

Estimating the normalization constants (partition functions) of energy-based probabilistic models (Markov random fields) with a high accuracy is required for measuring performance, monitoring the training progress of adaptive models, and conducting likelihood ratio tests. We devised a unifying th…

CMA-ES with Optimal Covariance Update and Storage Complexity

NeurIPS 2016poster

The covariance matrix adaptation evolution strategy (CMA-ES) is arguably one of the most powerful real-valued derivative-free optimization algorithms, finding many applications in machine learning. The CMA-ES is a Monte Carlo method, sampling from a sequence of multi-variate Gaussian distributions.…
