What Happens With BAMI?

Hi everyone,

This is my first post on this forum - as I just joined (although I’ve been watching Jeff and Numenta since more than 10 years ago).

My first question is about the HTM online book - BAMI. Is this being kept up to date by Numenta? If I understood correctly, this was supposed to contain the full theory and algorithms for HTM implementations. I’m confused because I didn’t see a note that it’s obsolete, but I see pointers to various articles on the details of the spatial pooler and the temporal memory. and BAMI doesn’t seem to have been updated in a relatively long time now.

I’m considering writing a full HTM implementation from scratch and I wonder if there’s enough detail available to do that. I wanted to do this for many years now (you could call me an experienced programmer), but I always felt the documentation available was not enough. Now there seems to be a bit more available, but where is the current reference material?



No one has seriously worked on BAMI in a long time. We prioritized other writings higher over the past couple of years. However I am planning on spending some time working on BAMI this year if all goes as planned. I would love to give it a facelift, turn it into a reference-able web asset, and do some updates.


I notice that the Chinese version of BAMI needs to be updated with HTM recent research work. I wonder if I can help you for translating English version into Chinese version.
I think that is the best way to learn about HTM theory.


@zzy824 Let me know if you are translating. I think I can help.

Now I am reading both Chinese and English version of BaMI. I have not started to translate, because I don’t have source files of BaMI(latex or markdown). Anyway, nice to meet you. I am in my first year of master in Computer Technology. You can know more about me at here. @marty1885

@zzy824 We decided not to continue working on BAMI, instead, I’ll be working on Building HTM Systems (WIP Document). Maybe this could be translated once we are finished with it?

Nice to meet you. The link you provided doesn’t seem to work.

I am very sorry for my carelessness. I have corrected the link above :smile: . Or you can go directly to https://zzy824.cn. My research track is Video description. You can add me via Wechat number(zhuzhengyuan002) if you use Wechat. Or through email(zhuzhengyuan824@gmail.com).
I am looking forward to hearing from you~

I have try my best to translate “Spatial-Pooling-Algorithm-Details” and “Temporal-Memory-Algorithm-Details” to Chinese.I hope it is useful.


Thank you @bcc! This is very useful for our Chinese readers. Please share with anyone you think will enjoy reading.
