Accuracy very low and not inccuracy near zero

My accuracy is around 0.04. Here is my model. Would you please take a look? I don’t know what I am missing here. Thank you.

The assignment is a multi-class classification problem. So, please fix your NN architecture.

Ah, sorry didn’t pay attention. So
I corrected it like this:

it says 26 alphabet letters. so I made it to 26.
But I have an error:

Do not know maybe some where else is missed? Please help. Thank you. :grimacing:

I did a little research to find that changing to sparse_categotical_entropy would solve the problem.

I tried and the accuracy increased.

But now it doesn’t like to plot for me. :thinking:

Would you please help me? Thank you very much.

Please look at this line metrics=[...]. Fix that to the right metric string and your model is good to go. acc is old style. Use accuracy instead.

Don’t forget to remove code from all your other posts on this thread.

Thank you very much Mentor :saluting_face:. I get it passed. I also removed codes.
