Where to find implementation of `visualize_class_saliency` and `visualize_regression_saliency`? #169

From https://github.com/raghakot/keras-vis/issues/38#issuecomment-311859428:

visualize_xxx now has a regression and class variant separated out.

However, nothing like this is in vis/visualization/activation_maximization.py, and in https://github.com/raghakot/keras-vis/blob/668b0e11dab93f3487f23c17e07f40554a8939e9/vis/visualization/saliency.py#L54-L55 it is only referred to, but not implemented anywhere.

Where can I read about visualize_class_saliency and visualize_regression_saliency?

I'm looking for visualize_regression_saliency.

Hi there.

visualize_class_saliency and visualize_regression_saliency don't exist. (I think, at first of developing keras-vis, there was possibility that they was created. I don't know the details, but, at least, they have not existed now.)

If you want to visualize saliency for outputs of regression model, you could use visualize_saliency or visualize_saliency_with_losses. And then the following links should help you.
