How do we extend this to TimeDistributed Layers? about keras-vis HOT 5 OPEN

Hi @raghakot, Great work! it was really useful for getting insights about my project results. I am working on a time series based data. I am doing a RNN classification task and It will be great if you could share the technique on how to use Keras-vis for saliency analysis in RNN(LSTM) models.

I am assuming the input is something like (batchsize, time_dims, input_dims, channels). The heatmap will simply be of the same shape which shows how the attention will vary over time_dims.

As for multi-label output. we have the ability to set multiple filter_indices. so filter_indices = [0, 5] would mean that outputs 0, 5 are on.

It would be really cool to have examples for these use-cases in examples/ folder. If your code is not confidential or proprietary, consider submitting an example PR. I am willing to work with you to get it working. Having a wide variety of examples/ is really the key rather than documentation to illustrate the various use-cases.

In either case, I can help you debug with any specific issues you might be having.

Hi @raghakot I have emailed you some test data and the model. If we can get it working, then we can post it as an example here.

Cool. Looking at it.

Minor update. With backprop_modifier='relu' in saliency, you do see something for weak_out.
Does it make sense? This is using the deconv approach from matthew ziegler's paper.

I am still working on a solution for TimeDistributed nets.
