These features are concatenated into one-dimensional data by means of a concatenation technique, of which the equations are shown in Equation (15). The final feature extraction in terms of spatial temporal patterns (𝒳(𝑡)Xt) is the input of a stacked BiLSTM in the classification process....
The weight–length relationship (WLR) of fish is a crucial tool in fish biology research and has received extensive attention. However, fish growth is influenced by many factors, and the WLR also changes accordingly. Our aim was to investigate how fish b
