Discontinuity of Lyapunov exponents vs Entropy for smooth surface diffeomorphisms
Jérôme Buzzi
Lyapunov exponents are fundamental invariants in smooth ergodic theory describing the asymptotic infinitesimal behavior along typical orbits. This text aims to explain how and why…
Centralized vs. Decentralized Security for Space AI Systems? A New Look
Noam Schmitt, Marc Antoine Lacoste
This paper investigates the trade-off between centralized and decentralized security management in constellations of satellites to balance security and performance. We highlight th…
Statements: Universal Information Extraction from Tables with Large Language Models for ESG KPIs
Lokesh Mishra, Sohayl Dhibi, Yusik Kim +4
Environment, Social, and Governance (ESG) KPIs assess an organization's performance on issues such as climate change, greenhouse gas emissions, water consumption, waste management,…
Online Multivariate Changepoint Detection: Leveraging Links With Computational Geometry
Liudmila Pishchagina, Gaetano Romano, Paul Fearnhead +2
The increasing volume of data streams poses significant computational challenges for detecting changepoints online. Likelihood-based methods are effective, but a naive sequential i…
Geometric-Based Pruning Rules For Change Point Detection in Multiple Independent Time Series
Liudmila Pishchagina, Guillem Rigaill, Vincent Runge
We consider the problem of detecting multiple changes in multiple independent time series. The search for the best segmentation can be expressed as a minimization problem over a gi…
Ms.FPOP: An Exact and Fast Segmentation Algorithm With a Multiscale Penalty
Arnaud Liehrmann, Guillem Rigaill
Given a time series in with a piecewise constant mean and independent noises, we propose an exact dynamic programming algorithm to minimize a least square criterion with a mu…
