This is because it has no features to actually to learn other than the minima that is seemingly present at 58% and one I wouldnt trust for actual cases. The best possible score is 1.0 and it can be negative (because the model can be arbitrarily worse). LSTM architecture network is the improved RNN architecture with the intention of implementing suitable BP training method. If you have an positive element whose score in your model is 0.9, you predict it to be of category 1 and you check the accuracy. edshkim98 (edward kim) April 4, 2021, 3:50am #1 Hi, I am currently training a LSTM model for binary classification.
