Hi cszn, I'm trying to train a model with other types of data. the data in the training data set can be more than 255? For example, 0-16384. Error shows 7.6 when I train the model.

Thanks!

You can normalize the range [0, 16384] into [-1, 1] ([0, 1]). In some cases, log also can help to narrow the range.
