Browser-based Neural Network Demo
What is a Neural Network?
It’s a technique for building a computer program that learns from data. It is based very loosely on how we think the human brain works. First, a collection of software “neurons” are created and connected together, allowing them to send messages to each other. Next, the network is asked to solve a problem, which it attempts to do over and over, each time strengthening the connections that lead to success and diminishing those that lead to failure. posted by CrystalDave (7 comments total) 35 users marked this as a favorite
tl;dr: hit the Play button.

If you spend a little time reading, it's a really lovely and powerful visualization of a neural network classifier. Lots of fun knobs to tweak and the orange/blue graphics make it possible to sort of divine intuitively what the network is doing.

The Swiss Roll is tricky.

(Fwiw this demo is not using Google's Tensorflow, it's based on ConvnetJS written by some Stanford smarty pants)

The last time I was this baffled was when I tried Snapchat. Is there a "for dummies" article somewhere that explains what is happening?

dominik: Here's an introduction to machine learning (more or less the same thing as a neural network) that lays out the basic concepts in a very comprehensible manner.

I wish they had dropout as a regularization method.

I studied the basics of neural networks and machine learnings in the university and it was one of the most interesting things that I've ever studied. Definitely something that can help in almost all aspects of life. Our professor even told believed that (when perfected) those types of algorithms can be used to determine the future.
Exciting times are coming, guys!
