In this work, we show that Latent Flow-Matching (LFM) models are robust to different types of perturbations, including data reduction and model capacity shrinkage. We characterize this stability by their tendency to generate similar outputs under identical noise seeds. We provide a perspective relat…
We design sensitivity oracles for error-prone networks. For a network problem Π, the data structure preprocesses a network G=(V,E) and sensitivity parameter f such that, for any set F of up to f link or node failures, it can report the solution of Π in G-F. We study three network problems Π. - L-Hop…
Detecting continuous gravitational waves using machine learning approaches is an active research topic. With signal strengths between 0.1% and 2%, this classification task is very difficult. The presence of noise makes it impossible even for humans to distinguish between data with and without traces…
We study the fundamental problem of selecting optimal features for model construction. This problem is computationally challenging on large datasets, even with the use of greedy algorithm variants. To address this challenge, we extend the adaptive query model, recently proposed for the greedy forwar…
Most networks are not static objects, but instead they change over time. This observation has sparked rigorous research on temporal graphs within the last years. In temporal graphs, we have a fixed set of nodes and the connections between them are only available at certain time steps. This gives ris…
Combinatorial optimization lies at the core of many real-world problems. Especially since the rise of graph neural networks (GNNs), the deep learning community has been developing solvers that derive solutions to NP-hard problems by learning the problem-specific solution structure. However, reproduc…
Optical character recognition (OCR) systems performance have improved significantly in the deep learning era. This is especially true for handwritten text recognition (HTR), where each author has a unique style, unlike printed text, where the variation is smaller by design. That said, deep learning…
