tsne

[tahmine88]

hi, how do you use tsne in a segmentation network to have such visualization?
thanks

i don't know how to gather pixels wise embeddings

Hi, you may save the embeddings into numpy files and then visualize tsne plots.

[tahmine88]

thanks for your response, is there any code or pseudo-code for it?

I think it's simply saving the features before the last layer of your network and visualize them with tsne.

thanks
they are 2D features, do you turn them into a vector then visualize it?! I don't think so! so how do you do that?

[curiosity654]

What do you mean by 2D features? If it's an HW 2D feature map with D feature dimensions, then you just flatten them into ND feature vector, here N=H*W, and feed it into the API together with labels.

thank you so much, I think I got it.

@tfzhou would you mind sharing the color for the tsne embedding?
