We get the Q, K, and V matrices using scaled dot-product attention for similarity computation. This softmax score determines the possibility of the current word in each word position in each sentence. The following is the formula of the attention mechanism. Attention(Q,K,V)=softmax(QKTdk)...
The evaluation results support the effectiveness of the BPI-MVQA model in VQA-Med. The design of the bi-branch structure helps the model answer different types of visual questions. The parallel network allows for multi-angle image feature extraction, a unique feature extraction method that helps ...
