Fig 6. Per epochs evaluation score for deep learning models.

In these figures, ‘val’ indicates validation, so ‘val_accuracy’ represents the accuracy on the validation set, and the same principle applies to other metrics (a) CNN + Original Data, (b) LSTM + Original Data, (c) CNN-LSTM + Original Data, (d) CNN + down-sampled data, (e) LSTM + down-sampled data, and (f) CNN-LSTM + down-sampled data.
