how to see saliency maps from middle layers #37

Closed YOONAHLEE closed 5 years ago

YOONAHLEE commented 5 years ago

Hi,

Do you know how to get neuron's saliency map from the middle layer? I want to pick some neurons from the middle layer and compare visualization result but I cannot figure out how to pick values to see an image from lots of gradients.

Thank you,

Hey,

Just do forward pass until the layer you want to visualize and perform gbp or vbp sourced from there.

Hi,

for getting gradients from middle layers after one iteration, like the example mention in ReadMe, how do you forward pass again?

utkuozbulak commented 5 years ago

Hey,

Check layer visualization file, you just modify the input image and forward pass again.
