Hey Dave,

You got some things right and some things wrong. In security, most problems are not image classification related and do 
not benefit at the same level from the recent advances in Convolutional Neural Networks. Also, TensorFlow is not the 
first freely available Deep Learning library nor is it the first freely available Machine Learning classification 
library by a long shot. Take a look at e.g. some of the presentations that the MLSec Project made available, ML has 
been in security products for decades (and I worked on shipping products with it back in the day working at CipherTrust 
before people cared what technology stopped the threats as long as they were stopped). What’s new is that Machine 
Learning now also appears on marketing materials. So the question one should ask oneself is whether you still have a 
product once the ML hype wore off.

Best,
-Sven

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.

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.

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.

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". 

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.

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.

And of course, the same thing is true for the process information El Jefe will give you. 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.
