How to make an adversary resistant neural network

I previously pontificated about the difficulties of making a neural network robust in the adversarial model and a general approach to overcoming them. In this post I’ll flesh out the specifics of the construction a bit more. What we want to do is make a neural network whose overall structure…

You’re doing computer chess game commentary wrong

Computer chess games are fun to play over, even if it’s just because you know that these are the best chess playing entities in the world and some of their wisdom is contained in the games they’re playing out. Commentary of course adds to the fun, but that leads to…

Gardens of Eden

Since John Horton Conway passed a few days ago now might be a good time to write up my thoughts on gardens of eden in his life automata. I’ve spent some time manually trying to find simple gardens of eden patterns and failed miserably, to the point where it seems…

Neural Networks as we know them are fundamentally flawed. Here are some thoughts on how to improve them.

This paper gives some technical attacks on neural networks. To understand what’s going on here, consider this plot to a Hollywood caper (which somebody should totally produce): An employee of a company wishes to steal a McGuffin from their vault.

Alphazero defeated Stockfish in a series of remarkable games marking, according to the common interpretation, a turning point where computer Chess will inevitably switch to deep learning based board evaluation.

Double Billing is not ‘Healthy Competition’

Let’s say that you’re running a company and want to create some internal competition between teams to see which ones can perform better. You can do this with R&D, and sales, but I would humbly suggest that you don’t do it with receivables. …
