Can Add Optimizers firstly, to reduce the train epochs?
from blackcat_tensors.
I can try to implement them next, however I am not super knowledgeable about ADAM so I will have to learn how it works. I can easily add momentum and some of the simpler optimizers to start though
from blackcat_tensors.
OK. Thank you very much. I test your newest code every data that you updata,quietly.

Thank you very much. It's too late, you must go to sleep.
I test it, somethings error with it, the loss stay at a hight level,and the predict output is so bad, as:

from blackcat_tensors.
It actually does work, for the LSTM example the learning rate was too high.
(Before it was .03 now its .003). It works with better accuracy than before now!

same net struct and same learning_rate, and same epochs, but the new code is wrose then before.

the loss is seems better, but the predict output seems not so better than before.

I don't know why it worser then before in my net srtuct and data.

Are you using the latest version?
In the newest version, "get_string_architecture"
now returns the input_shape and optimizer.
FeedForward:
input_shape: [784]
optimizer: Momentum
Tanh:
input_shape: [256]
FeedForward:
input_shape: [256]
optimizer: Momentum
SoftMax:
input_shape: [10]
Output_Layer:
input_shape: [10]
If you are still having issues you could try lowering the learning rate, momentum tends to work better with a smaller learning rate (compared to SGD)

thank you. When i set the learning rate to 0.0005,it is better then before.
