Une enquête complète en LLM(-Agent) Sécurité de la pile complète: Données, Formation et déploiement
Le succès remarquable des grands modèles linguistiques (LLM) has illuminated a promising pathway toward achieving Artificial General Intelligence for both academic and industrial communities, owing to their unprecedented performance across various applications. As LLMs continue to gain prominence in both research and...
Validation croisée conjointe Leave-Group-Out dans les modèles spatiaux bayésiens
Cross-validation (CV) is a widely-used method of predictive assessment based on repeated model fits to different subsets of the available data. CV is applicable in a wide range of statistical settings. Cependant, in cases where data are not exchangeable, the design of...
Estimation des paramètres bayésiens pour McKean-Vlasov partiellement observé Diffusions utilisant une chaîne de Markov multiniveau Monte Carlo
In this article we consider Bayesian estimation of static parameters for a class of partially observed McKean-Vlasov diffusion processes with discrete-time observations over a fixed time interval. This problem features several obstacles to its solution, which include that the posterior density is...
Validation du 3GPP TR 38.901 Modèle de perte de chemin de point d'accès intérieur basé sur Mesures effectuées à 6.75, 16.95, 28, et 73 GHz pour la 6G et au-delà
This paper presents a thorough validation of the Third Generation Partnership Project (3MPE) Rapport technique (TR) 38.901 point d'accès intérieur (InH) path loss model, dans le cadre de la version 3GPP 19 étudier sur “Validation du modèle de canal de TR 38.901 pour 7-24 GHz,” pour...
Textures de spin hors équilibre induites par des impulsions de vortex optique en orbite de spin électrons couplés
Optical vortex beams are a type of topological light characterized by their inherent orbital angular momentum, leading to the propagation of a spiral-shaped wavefront. Dans cette étude, we focus on two-dimensional electrons with Rashba and Dresselhaus spin-orbit interactions and examine how they...
Reconciling the Waiting Time Peaks Variations of Repeating FRBs with an Eccentric Neutron Star–White Dwarf Binary
Fast radio bursts (FRBs) are luminous radio transients with millisecond duration. For some active repeaters, such as FRBs 20121102A and 20201124A, more than a thousand bursts have been detected by the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The waiting time (WT) distributions...
Yet Another Diminishing Spark: Low-level Cyberattacks in the Israel-Gaza Conflict
We report empirical evidence of web defacement and DDoS attacks carried out by low-level cybercrime actors in the Israel-Gaza conflict. Our quantitative measurements indicate an immediate increase in such cyberattacks following the Hamas-led assault and the subsequent declaration of war. Cependant, the...
Analytical Softmax Temperature Setting from Feature Dimensions for Model- and Domain-Robust Classification
In deep learning-based classification tasks, the softmax function’s temperature parameter $T$ critically influences the output distribution and overall performance. This study presents a novel theoretical insight that the optimal temperature $T^*$ is uniquely determined by the dimensionality of the feature representations, thereby...
Multi-Modal Fusion of In-Situ Video Data and Process Parameters for Online Forecasting of Cookie Drying Readiness
Food drying is essential for food production, extending shelf life, and reducing transportation costs. Accurate real-time forecasting of drying readiness is crucial for minimizing energy consumption, improving productivity, and ensuring product quality. Cependant, this remains challenging due to the dynamic nature of...
[PK2008] HalphaJ115927 and IGR J14091-6108: Two new intermediate polars above the period gap
This study presents a detailed timing analyses of two cataclysmic variables (CVs), [PK2008] HalphaJ115927 and IGR J14091-610, utilizing the optical data from the Transiting Exoplanet Survey Satellite (TESS). Periods of 7.20$\pm$0.02 h, 1161.49$\pm$0.14 s, and 1215.99$\pm$0.15 s are presented for [PK2008] HalphaJ115927,...
