There are only a few real computers in the world, and I think we are
just beginning to feel their influence. For example, here is a
sample project I am working on now that image classification is a
solved problem.<br>
<br>
Like many of you on this list, I dabble in brazilian jiu jitsu. In
fact, in a week we are doing an open mat at INFILTRATE for both
newcomers who've always wanted to try to choke me out, to people in
the community who are already very good at choking people.<br>
<br>
Like many sports, BJJ is typically scored according to a ruleset
based on the different positions you end up in. Being on top is
usually better. Being able to get on top after you are on the bottom
is worth 2 points. Being able to completely mount someone is worth
three points. Getting on their back is four points. Generally a
tournament will hire judges and they will award points based on
their understanding of the rules and their personal feelings towards
the contestants and whatever other factors are floating in their
heads.<br>
<br>
What I'm working on is collecting a set of images of BJJ, then
annotating them as to what positions the different people are in.
This essentially maps every image into a vector space - and after
training a neural network using modern techniques you can have a
program that looks at an image and then outputs "Blue is in top
mount". <br>
<br>
Part of the key here is that you don't have to tell it that the
picture is BJJ. Every picture that program sees is two people doing
BJJ. All it has to do is output what positions they are in.<br>
<br>
And in the end, by assigning point values to transitions between
positions, you will have an automatic BJJ judge. I've applied for a
TensorFlow API key from Google since although this is not a hard
problem by ML standards I want to do it the right way and get good
scalable results on video later.<br>
<br>
And of course, the same thing is true for the process information <a

All those "behavioral analysis machine learning intrusion detection"
startups are about to be crushed by simple open source projects that
use Google and MS and Amazon's exported Machine Learning APIs. <br>
