What does lighter color mean in tensorboard?

I attached an image of my distributions on tensorboard. I can see some very light color in the graph. It looks very noisy. What is this?

Solution

  • These curves indicate percentile, in which the light color curves are max (99 th percentile) and min (1 th percentile).
    As the definition of percentile, a percentile is a number where a certain percentage of values are fall below that percentile value.
    For example in the following figure, assume that we are talking about steps 1000, at the 93 th percentile line, there were 93% of the values are below 0.200

    Why is (99th, 93th, 84th, 69th, 50th, 31th, 16th, 7th, 1th) but not other percentiles ? Because they were declared in the tensorboard README.md, which is documented here.
    Hope this helps !
