Hello Yuwei, Thanks for the input.
I agree that visualising 2D sdrs is hard. Be able to see 2D SDRs is something I'd like to do. I have some ideas but it'll take a bit more work. The sequence memory (or temporal memory as i think it's called now) is definitely something I'd like to see visualised. Its really hard to see what's gong on and it's one of the most important bits. Part of the challenge is that there's so much data. I think it'll be a matter of choosing carefully what to cut out. And then having different visualisations to show different parts of the data. Ruaridh Hi Ruaridh, The visualization will be extremely helpful to understand what's going on. The SDR viewer is very intuitive. Are you planning also to add topology? It can be challenging to visualize the evolution of 2D SDR over time. In addition to the spatial pooler output. It will also be useful to figure out how to visualize the synaptic connectivity pattern between cells in the temporal pooler during sequence learning. This can be challenging if you have multiple cells per column. Also, matplotlib seems to be a good library for scientific visualizations.
