Why is the error only getting bigger?

Question

Neural networks

Hello.
I have a problem with training a neural network.
The problem is the error, everything seems to be fine, the error decreases, but at some point it starts to increase.
What could be the problem?

Answer 1

It's probably because you're doing something wrong.
What kind of network you have, what you are doing there, what data you are submitting, and even what you ultimately actually display on the chart - we do not know. Therefore, with the question of where in all this mess you did something wrong, you can just as well turn to a fortuneteller. Any answer received here will actually be the same divination. Well, for example - let's guess and say "retraining".
