Visual Place Cell Encoding: A Computational Model for Spatial Representation and Cognitive Mapping
This paper presents the Visual Place Cell Encoding (VPCE) modèle, a biologically inspired computational framework for simulating place cell-like activation using visual input. Drawing on evidence that visual landmarks play a central role in spatial encoding, the proposed VPCE model activates visual...
Monocular inspection of spacecraft under illumination constraints and avoidance regions
This paper presents an adaptive control approach to information-based guidance and control of a spacecraft carrying out on-orbit inspection by actively computing optimal policies for the spacecraft to achieve the best possible representation of objects within its orbital environment. Due to the...
Instabilités d'anisotropie de température des électrons du vent solaire avec Kappa-halos régularisés résolus avec ALPS
Space plasmas in various astrophysical setups can often be both very hot and dilute, making them highly susceptible to waves and fluctuations, which are generally self-generated and maintained by kinetic instabilities. In this sense, we have in-situ observational evidence from the solar...
GratuitGraftor: Greffe de fonctionnalités multi-images sans formation pour Génération de texte en image basée sur le sujet
Subject-driven image generation aims to synthesize novel scenes that faithfully preserve subject identity from reference images while adhering to textual guidance, yet existing methods struggle with a critical trade-off between fidelity and efficiency. Tuning-based approaches rely on time-consuming and resource-intensive subject-specific optimization,...
Une nouvelle relation entre la durée des sursauts gamma et la photosphère Rayon
Long Gamma Ray Bursts (lGRBs) are associated with jets in Type Ic broadline supernovae. The Collapsar model provides a theoretical framework for the jet formation from the core collapse of a massive star in such supernovae. The GRB can only be produced...
From Human Memory to AI Memory: A Survey on Memory Mechanisms in the Era of LLMs
Memory is the process of encoding, storing, and retrieving information, allowing humans to retain experiences, connaissance, skills, and facts over time, and serving as the foundation for growth and effective interaction with the world. It plays a crucial role in shaping our...
Un cadre de jumeau numérique assisté par drone pour les réseaux IoT de haute précision et synchronisation
With the continued growth of its core technologies, including the Internet of Things (IdO), artificial intelligence (AI), Big Data and data analytics, and edge computing, digital twin (DT) technology has witnessed a significant increase in industrial applications, helping the industry become more...
Prédiction du destin des bogues dans les grands référentiels de logiciels open source grâce à l'analyse des sentiments et à la modélisation de sujets BERT
Cette étude explore une nouvelle approche pour prédire les principaux résultats liés aux bogues, y compris le temps de résolution, il est temps de réparer, et statut ultime d'un bug, en utilisant les données du projet Bugzilla Eclipse. Spécifiquement, we leverage features available before a bug is resolved...
Bien-être du transport des courants normaux en fonction du temps champs de vecteurs
We prove existence and uniqueness for the transport equation for currents (Geometric Transport Equation) when the driving vector field is time-dependent, Lipschitz in space and merely integrable in time. This extends previous work where well-posedness was shown in the case of a...
Découverte efficace du processus de transition de motif pour le temporel à grande échelle Graphiques
Understanding the dynamic transition of motifs in temporal graphs is essential for revealing how graph structures evolve over time, identifying critical patterns, et prédire les comportements futurs, yet existing methods often focus on predefined motifs, limiting their ability to comprehensively capture transitions and...
