Web15 aug. 2024 · To use multi-headed attention in your Pytorch model, you first need to define a AttentionLayer class. This class will take care of computing the attention for each head and applying it to the input. Once you have defined this class, you can then use it within your model by creating an AttentionLayer instance and passing it your input data. Web16 uur geleden · However, this fusion method may not fully utilize the complementarity of different data sources and may overlook their relative importance. To address these limitations, we propose a novel multiview multimodal driver monitoring system based on feature-level fusion through multi-head self-attention (MHSA).
