couple questions about the accuracy

[aHaidiChen]

Hello,
I really like your idea of the usage of 2D COV to LOB data and the attention layer. I have couple questions ; maybe you also think about them before. First, the accuracy doesn't improve much after several Epochs. Is that normal or suggesting an overfitting -- as the model has so many layers and the structure is complex. Second, can this model applied to regression problems? I changed the decoder input to shape (1,1), and decoder_dense output shape to 1. However, it often predict a constant y-pred value. Does that mean this structure is not suitable for regression problems? or need to be simplified. Thank you so much.
