Large Multi-Modal Models (LMMs) as Universal Foundation Models for AI-Native Wireless Systems

no code implementations30 Jan 2024 Shengzhe Xu, Christo Kurisummoottil Thomas, Omar Hashash, Nikhil Muralidhar, Walid Saad, Naren Ramakrishnan

Diverging from NLP-based foundation models, the proposed framework promotes the design of large multi-modal models (LMMs) fostered by three key capabilities: 1) processing of multi-modal sensing data, 2) grounding of physical symbol representations in real-world wireless systems using causal reasoning and retrieval-augmented generation (RAG), and 3) enabling instructibility from the wireless environment feedback to facilitate dynamic network adaptation thanks to logical and mathematical reasoning facilitated by neuro-symbolic AI.

Causal Semantic Communication for Digital Twins: A Generalizable Imitation Learning Approach

no code implementations25 Apr 2023 Christo Kurisummoottil Thomas, Walid Saad, Yong Xiao

The causal structure in the source data is extracted using novel approaches from the framework of deep end-to-end causal inference, thereby enabling the creation of a semantic representation that is causally invariant, which in turn helps generalize the learned knowledge of the system to unseen scenarios.

Neuro-Symbolic Causal Reasoning Meets Signaling Game for Emergent Semantic Communications

no code implementations21 Oct 2022 Christo Kurisummoottil Thomas, Walid Saad

In this paper, a novel emergent SC (ESC) system framework is proposed and is composed of a signaling game for emergent language design and a neuro-symbolic (NeSy) artificial intelligence (AI) approach for causal reasoning.

Neuro-Symbolic Artificial Intelligence (AI) for Intent based Semantic Communication

no code implementations22 May 2022 Christo Kurisummoottil Thomas, Walid Saad

Novel analytical formulations are developed to define key metrics for semantic message transmission, including semantic distortion, semantic similarity, and semantic reliability.
