Description

Running some HTM.Java demos: https://github.com/numenta/htm.java/tree/master/src/main/java/org/numenta/nupic/examples/cortical_io

A

A little big, um I thought I would show you some HTM java demos. So in the July you pick hackers archive.

A

There is yeah message here from david ray tells you hey here's some demos, one of them is called Fox eats demos which may be familiar with its 11 of the first popular demos. We did on NLP using cortical I. Oh david ray works with cortical, and so he's I'm going to show you how to run this.

A

So I have I got. You have to run it from the command line. With a quarter lot: cortical I okie. I have a chordal I okie, I think somewhere.

A

I think it's called just court of ohio api key here. Let me find it real, quick off the screen.

A

This okay cortical api key is, what's called ok back to you, guys, okay, so let's loops we're gonna run this demo. It's going to look cool, want to smudge that so guys don't steal my cortical key. So I know you will ok, mmm let's go into fox eat, Spock seats. There should be a jar file here and then I'm going to put my cortical I okie right here, vertical API, key I think this will work. Let's try their gums all right.

A

What does a fox eat and I'm gonna make this real big click start and now its training input phrases, froggy fly, count, eat grain elephant eat leaves go, eat, grass, etc, etc, etc. It's feeding and all these things, animals eat or likes other things and then at the end it will say: Fox eats what let's see, think and think and think and answer a squirrel so success. So we've got the fox eat demo in HTM java, so that's cool and then we also have the other one, which is breaking news.

A

This came from the last hackathon and I think it's the pretty much the same command.

A

This is a from you I perspective, a lot more impressive in my opinion, and just because you get to see all of the cortical fingerprints, cortical API key.

A

And this is going to like scour Twitter. So if you have some control here, I was going to start it's on auto start, and so it's David would be able to explain what this is doing a little bit better. But it's getting like breaking news tweets from BBC breaking and showing you the fingerprint of the tweets over here.

A

I, don't know what show activity meets ah there we go so this is, you can either show what's the activity of what this app is doing or show the fingerprints fingerprints is cooler so and it's showing you the prediction of what it, after this sequence of tweet fingerprints, what it thinks is coming next, as this is interesting, especially because it's a combination of cortical, io technology and HTM technology.

A

So I usually don't leave this running for too long, because it's pretty intense, let's see how my cores are getting used here.

A

It's not a not as bad as HTM engine you're, writing hundreds of models, but top, but still I think this is a really cool visualization to show you know, I think you know Court of Ohio, word word and word: fingerprints or phrase, fingerprints or just text.

A

Fingerprints in general are just really cool to see, and so- and this actually shows you a prediction of what it thinks is next and then the comparison Toback of what came next, when it seems predictions really sparse, so I think that sort of tells us that it's not so sure about what's going on. But anyway, that's that's the demo. Oh, you can stop this and like switch over to manual and it's start again and then just go like one at a time.

A

If you want to control stepping but I, usually just flip the manual or auto anyhow there you go it's a example of some of David raised, HTM, Java demos, I think the UI is really nice David. Would you use for you I? Is this? What is it called FX? Something like that? It's in Java you, I tech anyway. Take care see you later.
