Hi @Tech_LingQi
we are currently not actively working on incorporating SDRs into Monty (but are not opposed to doing this in the future). We did explore using SDRs, HTM, and grid cells in the very beginning of Monty but hit some roadblocks. Here are two videos summarizing that project:
Since we didn’t have a use case yet where we couldn’t achieve the same functionality without SDRs it hasn’t been a priority on our research agenda. If you are interested in our general thinking around incorporating more neural elements into Monty, here is a nice summary from Niels: https://youtu.be/lewMhwzNtEo?si=BZiCMZcIDAACRnNn
One other SDR project we did (the one you saw in the code) was about using SDRs for the object IDs that learning modules output and encoding object similarity in those. Here is a video about this project: https://www.youtube.com/watch?v=qHdl8tlzY3k and documentation: Evidence as a Similarity Measure However, this is not part of our current default Monty configuration. If you have any questions around this work, @rmounir would be best to ask.
I want to highlight that just because we are currently not working on this ourselves doesn’t mean that we would want to discourage others from working on it. If you are interested in implementing an SDR-based learning module and plugging it into Monty, we’d be excited to hear about your progress and results.
Best wishes,
Viviane
