You might not have heard about it, but the NuPIC mailing lists had to be migrated to a private server recently, so we had a short outage. Once the lists had been moved, I wanted to reengage our community members after a couple day of limited messages, so I asked everyone to introduce themselves, and we’re getting some really fascinating responses. The NuPIC community is quite diverse and passionate! You might enjoy reading through some of the responses on each of our lists (look for the topics entitled “We’re back in business, introduce yourself!”.
Here are some interesting excerpts:
Currently, I am working with a student in collaboration with an expert MD on using NuPIC for analyzing medical vital signs for diagnosis of medical conditions and early warnings on abnormal incidents. We are at the first stages of this work. I will let you know if we get some promising results.
- Spyros Vassilaras, PhD
Thx Numenta for creating this awesome community.
- Alex GuangTou
For a while long ago i seriously thought i would be an opera singer, but despite great bass notes i couldn’t hit a high G, so that career ended abruptly. And as of yesterday i appear to be a cancer survivor, so yay!
- Matthew Lohbihler
NUPIC should be renamed to EPIC:-)
- Chirag Mirani
I am new to opensource but it is surprising how cool and encouraging the NuPIC community is and it has set a very high standard for opensource communities in my mind. Thanks NuPIC.
- Anubhav Chaturvedi
I’m really excited about what Numenta is doing and will be doing a small presentation about the CLA and NuPIC in my college soon!
- Kevin Martin Jose
I regard following the progress of Numenta as the most interesting news available. I wish to someday implement a version of Nupic in a consumer product.
- Dave Petrillo
I discovered Jeff from his Triangulation interview back in April and have been hooked ever since.
- Ryan Belcher
I’d say the only thing I don’t really understand about HTM is why there is not even more widespread interest for it from the AI community.
- Angela Bovo
I was one of the season-of-nupicers this year which was pretty interesting. I made an experimental visualisation library for NuPIC. Which i hope to properly release soon.
- Ruaridh O’Donnell
I have developed a good intuition for the characteristics of our brain and central nervous system as models for IT simulations and the CLA, HTM, SDR concepts together are very brilliant and worth their weight in gold. As it turns, I also apply some data science to some of the data in our systems and I believe that GROK may one day be a good solution for some future applications. For now, this is a hobby I follow with enthusiasm.
- Joe Perez
Then I stumbled on one of Jeff’s keynotes online and it blew my mind. Now I’m working to understand/develop/apply HTM, and build the future with you all
- Felix Andrews
By day I lead the Cloud Foundry team at HP, but ever since I saw Jeff speak at OSCON last year, I’ve been digging neocortical simulations. I’m particularly interested in the realm of procedurally generated content in games and other media, and I hope to do a session about Machines the Tell Stories at SXSW Interactive next year.
- Jeff Kramer
And lastly, you gotta read this wonderful interaction between a high school student and an elderly Chinese PhD:
Hi, Anthony Liu:
☺, I am this too old, and you are so young !
I had lived at bay area for some years, that is an area creating stories, always.
I love this stuff! NuPIC bringing people together from all walks of life FOR SCIENCE!!!! Big thanks to the NuPIC community for being such good people.

We have developed and open-sourced a project called the NuPIC Geospatial Tracking Application, which demonstrates how NuPIC can be used to provide anomaly indications for geospatial data. Specifically, it can accept GPS track information in GPX format and output indications of anomalous activity for each point along the tracks. This could be useful for a number of interesting applications:
You can see a simple tutorial of how to import GPS information from standard GPX files in this video:
Numenta has also authored a white paper entitled Geospatial Tracking: Learning the Patterns in Movement and Detecting Anomalies, which provides details about our motivation, potential use-cases, and underlying technologies.
At the heart of this new capability is the
GeospatialCoordinateEncoder, which converts geospatial coordinate information into a format that is compatible with NuPIC, exposing the characteristics of location information that allows the cortical underpinnings of NuPIC to understand it. In a way, this is analogous to providing a “new sense” of location awareness that we humans currently don’t have. For details about how the Geospatial Coordinate Encoder works to encode this data for NuPIC, see the following video by Numenta engineer Chetan Surpur:
We hope this demonstration of NuPIC’s geospatial tracking capabilities inspires others to create more interesting implementations in the fields listed above. The NuPIC Geospatial Tracking Application is really just a showcase, and a simple implementation to demonstrate NuPIC’s efficacy in this field.

We had a great hackathon event this past weekend. This was our third hackathon, and it resulted in the most hackers, the most hacks, and the most productive environment yet. Even if you could not attend, I hope the videos and photographs below help you to understand NuPIC better by example.
Below, you’ll find the following:
Big thanks to Pinger, who graciously donated their space to us for the event!
The hackathon brought in attendees from all over the world. We started at 10AM on Saturday with a kickoff presentation, helped people get NuPIC installed, then held several informational sessions throughout the day. Breakfast, lunch, and dinner were served.
Everyone seemed to have a great time, and most people stuck around through the event (sans some sleep time!) to see the demos at the end.
"Another outstanding event! Thanks Numenta!"
"Learned a ton, great people, great numenta staff, matt++ :)"
"It was great to meet the community and to exchange ideas"
"Comparing with the Fall 2013: 1. More people with serious interest in the NuPIC/Theory, 2. More hacks worked on and presented, 3. Previous "hacks" extended (CEPT!), 4. Theory has made progress towards deeper understanding of brain. Great to see the people from Numenta, the previous event, and new people with practical interest !"
"Really great, even better than in the Fall. Thanks to everyone who worked really hard to make the hackathon go so smoothly, and to all who took part. It was a real pleasure to meet so many smart people, all interested in furthering Machine Intelligence."
Where hackers are welcomed to the hackathon, protocol is reviewed, and ideas are brainstormed.
A detailed introduction to the components of NuPIC. Includes encoders, the spatial pooler, and swarming. Contains live code running in an iPython Notebook, which is included as a reference.
Subutai talks about how anomaly detection works in NuPIC, as well as how Grok processes NuPIC's anomaly scores to provide better "anomaly likelihood" values.
Jeff sits down for an up-close-and-personal discussion about his ideas about temporal pooling. Attendees ask him questions as he describes his theories on the whiteboard.
Numenta engineer Chetan Surpur goes into great detail about the implementations of the spatial and temporal poolers in NuPIC.
Matt talks about how far we've come as an open source project in the past year, the current state of NuPIC, and plans for the future.
We had a lot of demos at this hackathon! In addition to the full playlist of all our hackathon demonstrations, I’ve broken out each hack below with further information about the participants and source code (if available).
An attempt to get NuPIC to report anomalies when the characteristics of audio input changes.
Steve incorporated NuPIC into the TuxPuck program to help control a player against an AI adversary.
An attempt to configure NuPIC to predict the orbit of a satellite.
Craig trains NuPIC to play a first person shooter.
A platform for showing visualizations of a CLA model, which includes a 3D display of both spatial pooler and sequence memory components.
An easy point-and-click solution to deploying NuPIC within AWS.
Julie hooks up NuPIC to analyze web browser history to predict which website domain you'll be navigating to next.
Explores the space of how NuPIC might help analyze events streams in client-based software. In this case he analyzes events coming from Internet Explorer.
The goal was to mix different types of data about the same concept (words) and feed them into the CLA.
Analyzing speech data (TIMIT), trying different experiments to try to use NuPIC to predict male vs female speakers. Also explored different representations of the audio signal to see what works best with NuPIC.
Trying to teach NuPIC to understand complex word associations with CEPT word SDRs.
Wade uses NuPIC to try help with authentication not only by the password entered, but also the characteristics of the keystrokes entered.
An interesting hack using NuPIC to identify anomalous behavior using Facebook check-ins.
This was our most successful hackathon yet. Thanks to everyone who participating in the event, helped out with the planning and execution, and even for those of you watching the videos now. I hope you’ll considering attending our next hackathon!
