Following up on this very old post, I finally got around to making an interactive tool that allows you to make these visualizations and configure arbitrary encoder setups. You can try it out here.
I haven’t yet put very much explanation on how things work, but if you have even a little background on the subject of encoders, you can play around with it and see how changing different parameters changes the visualizations.
Things you can do:
- configure scalar encoders that encode an interval or are periodic like grid cells.
- interactively change the parameters and have the plots immediately reflect this change.
- display the encoded bits, color-code them by sub-encoder, sort them by activation (I got this idea from Matt Taylor’s early visualization experiments), and show the 1/0 value or the index value.
- Display 7 different kinds of plots: encoder bins, point similarity, bit codes, self-similarity heatmap, point similarity heatmap, regional granulation, bit flip crossings.
- interactively move the a slider cursor to see how the input value changes the encoding
- turn plots on and off, and resort their order
There’s a bit more, but that should be enough to get you started.
This is a continuing effort from my previous post on my Interactive Visualization of Discrete Cortical Circuits (DCC).
The latest demo of which you can find on my research blog.
