How many epochs should I train my model with?
The right number of epochs depends on the inherent perplexity (or complexity) of your dataset. A good rule of thumb is to start with a value that is 3 times the number of columns in your data. If you find that the model is still improving after all epochs complete, try again with a higher value. If you find that the model stopped improving way before the final epoch, try again with a lower value as you may be overtraining. If you have only a small number of records in your dataset or are having a large number of records fail validation, you may need to increase the number of epochs significantly to help the neural network learn the structure of the data.
