hi, my accuracy is too low: [image] Since I can’t upload code, let me just describe the model: Conv2D(64, (3,3), activation=‘relu’, input_shape=(28, 28, 1)) MaxPooling2D(2, 2) Conv2D(128, (3,3), activation=‘relu’) MaxPooling2D(2,2) Flatten() Dropout(0.2) Dense(512, activation=‘relu’) Dens…

For how long have you been training this network? The loss seems to be very low for training which should be good.

I trained for 15 epochs, the accuracy is 0.06 thats like 6%. What can i do?

I took this course many years ago and don’t have access to the current notebooks, but is this MNIST data? Guessing from the input shape. If so, don’t you need/want the output layer to have a dimension of 10? And if that causes a conflict with your chosen loss function, the solution isn’t to change…

What is the horizontal axis on those plots?

epoch It’s loss or accuracy by epoch

Looks like there’s no training happening, and the validation cost is the default value of 0.

I am also facing similar problem. The loss is showing as nan (and you could have gotten 0 loss on the plot because of this). Please let me know if you have fixed the issue.

NaN means “not a number”. It means your code has an error.

This is what my data looks like as well. I just posted about this issue too. [image] C2_W4 Assignment: I've read most of the forum posts about low accuracy issues, but none of the solutions are working TF1 Course 2 Week 4 I have read the various forum posts about the C2_W4…

Very low accuracy
