This thesis proposes an innovative alternative combining lightweight convolutional neural networks (Lightweight CNN) and causal graph neural networks (Causal GNN) for efficient spatio-temporal analysis while optimizing computational resources. Lightweight CNNs enable high-performance extraction of visual features, while causal GNNs model dynamic relationships between objects in a scene graph, addressing challenges in object detection and relationship prediction in complex environments. Unlike current transformer-based models, this approach aims to reduce computational complexity while maintaining competitive accuracy, with potential applications in embedded vision and real-time systems.<\/p>","protected":false},"featured_media":0,"template":"","categories":[165],"tags":[],"class_list":["post-12423","offre-emploi","type-offre-emploi","status-publish","hentry","category-nouveaux-paradigmes-informatiques-dont-calcul-quantique"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/offre-emploi\/12423","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/offre-emploi"}],"about":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/types\/offre-emploi"}],"wp:attachment":[{"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/media?parent=12423"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/categories?post=12423"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/talentimpulse.cea.fr\/en\/wp-json\/wp\/v2\/tags?post=12423"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
