Ising on the Graph: Task-specific Graph Subsampling via the Ising Model

no code implementations15 Feb 2024 Maria Bånkestad, Jennifer Andersson, Sebastian Mair, Jens Sjölund

Typically, the reduction approaches either remove edges (sparsification) or merge nodes (coarsening) in an unsupervised way with no specific downstream task in mind.

Provably-Correct Safety Protocol for Cooperative Platooning

no code implementations13 Dec 2023 Sebastian Mair, Matthias Althoff

Cooperative Adaptive Cruise Control (CACC) is a well-studied technology for forming string-stable vehicle platoons.

On Feynman--Kac training of partial Bayesian neural networks

1 code implementation30 Oct 2023 Zheng Zhao, Sebastian Mair, Thomas B. Schön, Jens Sjölund

Recently, partial Bayesian neural networks (pBNNs), which only consider a subset of the parameters to be stochastic, were shown to perform competitively with full Bayesian neural networks.

Personalized Privacy Amplification via Importance Sampling

no code implementations5 Jul 2023 Dominik Fay, Sebastian Mair, Jens Sjölund

We first consider the general case where an arbitrary personalized differentially private mechanism is subsampled with an arbitrary importance sampling distribution and show that the resulting mechanism also satisfies personalized differential privacy.

Resilience in Platoons of Cooperative Heterogeneous Vehicles: Self-organization Strategies and Provably-correct Design

no code implementations27 May 2023 Di Liu, Sebastian Mair, Kang Yang, Simone Baldi, Paolo Frasca, Matthias Althoff

We show that self-organization promotes resilience to acceleration limits and communication failures, i. e., homogenizing to a common group behavior makes the platoon recover from these causes of impairments.

Self-Supervised Siamese Autoencoders

no code implementations5 Apr 2023 Friederike Baier, Sebastian Mair, Samuel G. Fadel

In this paper, we present a new self-supervised method that combines the benefits of Siamese architectures and denoising autoencoders.

Archetypal Analysis++: Rethinking the Initialization Strategy

no code implementations31 Jan 2023 Sebastian Mair, Jens Sjölund

Archetypal analysis is a matrix factorization method with convexity constraints.

Principled Interpolation in Normalizing Flows

no code implementations22 Oct 2020 Samuel G. Fadel, Sebastian Mair, Ricardo da S. Torres, Ulf Brefeld

In this paper, we solve this issue by enforcing a fixed norm and, hence, change the base distribution, to allow for a principled way of interpolation.

Coresets for Archetypal Analysis

1 code implementation NeurIPS 2019 Sebastian Mair, Ulf Brefeld

Archetypal analysis represents instances as linear mixtures of prototypes (the archetypes) that lie on the boundary of the convex hull of the data.

Quantization

Frame-based Data Factorizations

no code implementations ICML 2017 Sebastian Mair, Ahcène Boubekki, Ulf Brefeld

Archetypal Analysis is the method of choice to compute interpretable matrix factorizations.
