A Transformer for Joint Multi-Receiver Pilotless Wi-Fi Decoding
Xavier Tardy, Grégoire Lefebvre, Apostolos Kountouris +2
In this paper we discuss the development of a fully pilotless multi-access-point Wi-Fi receiver. This is based on a self-attention Transformer that operates on per-(access point, s…
Intent-Based Orchestration in Open RAN: An ns-3 Simulation Framework
Pouya Agheli, Grégoire Lefebvre
This paper presents an extensible ns-3-based simulation framework for evaluating intent-based, semantics-aware control in Open RAN architectures. The framework integrates external…
Scalable Cross-Attention Transformer for Cooperative Multi-AP OFDM Uplink Reception
Xavier Tardy, Grégoire Lefebvre, Apostolos Kountouris +2
We propose a cross-attention Transformer for joint decoding of uplink OFDM signals received by multiple coordinated access points. A shared per-receiver encoder learns the time-fre…
Accommodating Missing Modalities in Time-Continuous Multimodal Emotion Recognition
Juan Vazquez-Rodriguez, Grégoire Lefebvre, Julien Cumin +1
Decades of research indicate that emotion recognition is more effective when drawing information from multiple modalities. But what if some modalities are sometimes missing? To add…
Emotion Recognition with Pre-Trained Transformers Using Multimodal Signals
Juan Vazquez-Rodriguez, Grégoire Lefebvre, Julien Cumin +1
In this paper, we address the problem of multimodal emotion recognition from multiple physiological signals. We demonstrate that a Transformer-based approach is suitable for this t…
Transformer-Based Self-Supervised Learning for Emotion Recognition
Juan Vazquez-Rodriguez, Grégoire Lefebvre, Julien Cumin +1
In order to exploit representations of time-series signals, such as physiological signals, it is essential that these representations capture relevant information from the whole si…
