[PhD] Geometric-Semantic Adaptation of Multimodal LLMs for High-level Landmark Detection in Complex Environments

test

General information Description Context Landmark detection, description and matching is the cornerstone of autonomous visual localization systems deployed in unknown environments. While most widely-adopted and accurate solutions exploit low-level landmarks (i.e., points or lines), dealing with large-scale and visually ambiguous environments remains highly challenging due to the inherent multiplicity, ambiguity…

[PhD] BAYESIAN RECEIVER DESIGN AND BEAMFORMING FOR MULTIUSER MIMO THZ COMMUNICATIONS USING PROBABILISTIC GRAPHICAL MODELS AND GRAPH NEURAL NETWORKS

test

Abstract: Wireless communications in sub-THz and THz bands are considered a key enabler for future 6G networks due to the abundance of unused spectrum and the potential for ultra-massive MIMO (UM-MIMO) systems that achieve terabit-per-second data rates and precise localization. However, challenges such as severe path loss, blockage, hardware impairments,…

[PhD] ANR: On-line change detection on Lie groups for satellite attitude control

test

ContextDetecting abrupt changes consists in identifying the instants when the statisticalbehavior of a system changes significantly. This problem is crucial in awide range of engineering applications, where faults, environmental changes, oroperational mode switches may occur. In a real time setting, detecting suchchanges must be performed on-line, i.e. whenever a sensor…
