# Looking at the loss curve, it is clear that we are overfitting (note that the orange training curve is well below the blue eval curve). Both loss curves and the accuracy-per-sequence curve, which is our key evaluation measure, plateaus after 40k. (The red curve is a faster way of computing the evaluation metric, and can be ignored). So, how do we improve the model? Well, we need to reduce overfitting and make sure the eval metrics keep going down as long as the loss is also going down.
# <p>
# What we really need to do is to get more data, but if that's not an option, we could try to reduce the NN and increase the dropout regularization. We could also do hyperparameter tuning on the dropout and network sizes.
