Interesting to see how well separated they are, it is odd to see a couple yellow no-lasing samples show up in the blue lasing area. The patch of blue lasing samples in the no-lasing area - that are so far away, is odd.
Things to investigate
- Different choices for perplexity
- More data
- t-sne with the enPeaksLabels - the 0,1,2,3
- Running t-sne from different points in vgg16 net, ie, try
- both codeword1 and codeword2, the 8192 final values
- just codeword1
- just the output of convolutions
- Run t-sne directly on the input images
- Look up the input images, what do the lasing images in the blue blob that lives with the no-lasing have in common? Recall the 'lasing' was filtered, we have to measure a e1 or e2 in the enPeaksLabel, are those just mislabelings? They have no lasing to notice? Or is there some other structure in them?
