In a Streaming World, Should You Stand Still? A Comprehensive Benchmark of Anomaly Detection in Streams

Magali Parrino, Antoine Ajenjo, Emmanuel Remy +3

Time series anomaly detection (TSAD) is increasingly deployed in streaming settings, where data arrive sequentially and may exhibit non-stationarity. As a result, several works fro…

Exact Algebraic Computation of Learning Coefficients for Two-Dimensional Singular Models

Grégoire Sergeant-Perthuis, Elias Tsigaridas, Jules Tsukahara

Classical information criteria such as the Bayesian Information Criterion (BIC) rely on regularity assumptions that break down for singular models, leading to incorrect model selec…

Attacking the First-Principle: A Black-Box, Query-Free Targeted Mimicry Attack on Binary Function Classifiers

Gabriel Sauger, Jean-Yves Marion, Sazzadur Rahaman +3

Binary function classifiers play a crucial role in maintaining the security and integrity of software systems by detecting malicious code and unauthorized modifications. However, m…

Link Prediction or Perdition: the Seeds of Instability in Knowledge Graph Embeddings

Guillaume Méroué, Fabien Gandon, Pierre Monnin

Embedding models (KGEMs) constitute the main link prediction approach to complete knowledge graphs. Standard evaluation protocols emphasize rank-based metrics such as MRR or Hits@$…

Learning from a single labeled face and a stream of unlabeled data

Branislav Kveton, Michal Valko

Face recognition from a single image per person is a challenging problem because the training sample is extremely small. We consider a variation of this problem. In our problem, we…

Conditional anomaly detection with soft harmonic functions

Michal Valko, Branislav Kveton, Hamed Valizadegan +2

In this paper, we consider the problem of conditional anomaly detection that aims to identify data instances with an unusual response or a class label. We develop a new non-paramet…
