I\'m trying to predict price by characteristics.
I chose a pretty simple model, but it works very strange. Loss function is extremely high and I can\'t see where the problem
As I can see, you are using a regression model, so with a regression model your loss will be completely different from what it would be if you used the model for classification
If you need classify. set the loss function in the likeness of categorical_crossentropy or another. And set activation func for last layer in your ml.
