Minimax Rates of Convergence for Nonparametric Regression Under Adversarial Attacks

Peng, Jingfu · Yang, Yuhong

Recent research shows the susceptibility of machine learning models to adversarial attacks, wherein minor but maliciously chosen perturbations of the input can significantly degrade model performance. In this paper, we theoretically analyse the limits of robustness against such adversarial attacks in a nonparametric re...

Cryo-electron microscopy EPN/Grenoble BAG

Pauline JUYOUX · Maria BACIA · Ambroise DESFOSSES · Guy SCHOEHN

ESRF is privileged to host two state-of-the-art microscopes. Our BAG unites the majority of local labs that utilise cryo-EM to address their diverse structural biology questions, including researchers from the EPN campus (IBS, ESRF, ILL and EMBL) and its vicinity (Cell & Plant Physiology Laboratory LPCV, Grenoble Insti...

Fate of mixed CH4-CO2 clathrates in large icy satellites

Anna PAKHOMOVA · Olivier BOLLENGIER · Tiziana BOFFA BALLARAN · Alexander KURNOSOV

Within a growing number of icy satellites of the outer solar system, the presence of liquid water has been suggested in a form of subsurface oceans. An intriguing aspect of extra-terrestrial ocean worlds is the influence of high pressure (HP) on their physical state and thermochemical evolution. While a variety of vola...

Mean Independent Component Analysis for Multivariate Time Series

Lee, Chung Eun · Li, Zeda

In this article, we introduce the mean independent component analysis for multivariate time series to reduce the parameter space. In particular, we seek for a contemporaneous linear transformation that detects univariate mean independent components so that each component can be modeled separately. The mean independent...

Belgium BAG

Christoph MUELLER DIECKMANN · Laurens BOURDA · Sergei STRELKOV · Thibault VANTIEGHEM

The Belgium BAG includes groups situated at four Flemish universities: Antwerpen, Brussels, Ghent and Leuven. The proposed projects are highly diverse, including viral, prokaryotic and eukaryotic proteins with a strong focus on targets and processes of biomedical relevance. Many projects deal with membrane proteins, ce...

Gaussian Variational Approximation with Composite Likelihood for Crossed Random Effect Models

Xu, Libai · Reid, Nancy · Kong, Dehan

Composite likelihood usually ignores dependencies among response components, while variational approximation to likelihood ignores dependencies among parameter components. We derive a Gaussian variational approximation to the composite log-likelihood function for Poisson and Gamma regression models with crossed random...

Liquidity, Indebtedness, and Operational Efficiency in Selected Logistics Companies – A Descriptive Analysis

Martinčević, Ivana · Sesar, Vesna

This paper examines the relationship between liquidity, indebtedness, and operational efficiency in selected logistics companies with the aim of assessing their financial stability. The research is based on a descriptive and comparative analysis of financial indicators obtained from publicly available financial stateme...

The Relationship between ESG Orientation and Governance Quality

Globočnik Žunac, Ana · Sesar, Vesna

Environmental, Social, and Governance (ESG) principles have become increasingly important for organizations seeking to strengthen sustainability and stakeholder relationships. Elaborating on Stakeholder Theory and Signaling Theory, this study examines the relationship between governance-related dimensions and employees...

Ventriloquation and CCO Research: Organizational Communication and Agency

Quand le contexte géopolitique s’en mêle : fabrication des poids de l’agoranome Hérode au cours de l’année 214 de l’ère séleucide

Delmeulle, Matthieu

À la fin du IIe siècle a. C. n., la domination séleucide du Levant Sud s’estompe peu à peu tandis que les Hasmonéens étendent progressivement leur souveraineté sur l’ensemble du territoire. La série des poids à la proue de Ptolémaïs-Akko et l’ensemble des poids au bouclier macédonien de Marisa montrent une influence de...
