The perceptron - In 1957, Frank Rosenblatt came up with the perceptron. The perceptron is a simple neural network that was able to recognize simple shapes. Unfortunately, Rosenblatt got a little over excited,

How neurons work - If you look at only one neuron—one brain cell—how it behaves is actually fairly simple. Today, we cover the relatively simple basics of how neurons work.

A bit of history - Before we try and figure out how to simulate the brain, let’s take a quick look at how we figured out that the brain is where we figure out.

Tierra, bits bytes and life - In the early 1990/s, a biologist named Thomas Ray created a computer program that acted like a computer infected with many little programs. He called it Tierra, Spanish for “Earth.” The little programs could, and did,

Core Wars - In 1984, the game Core Wars was written and introduced to the public. Contestants write programs in a special language called redcode, and attempt to halt or overwrite the other programs in order to be the last game standing. -

Darwin, the game - In the summer of 1961, a game was created. It was a programming game. Players would write programs that would compete against one another to try and copy themselves as often as possible,

Meanwhile, elsewhere on the planet - I wanted to do something special for episode 100. It snuck up on me, and I never figured out what to do. I decided to share a couple of other projects, outside of the podcast. -

256 simpler games - In the 1980/s, Stephen Wolfram began considering and experimenting with elementary cellular automata. These are, instead of a 2-dimensional grid, just a one-dimensional row of cells or squares. At least one of these simpler games,

Conway’s game of life - In the previous episode we talked about cellular automata, and John von Neumann’s self-replicating system. While he used cellular automata with 29 different states for each cell, a much simpler game is capable of creating self-...

Von Neumann’s cellular automata - John Von Neumann began considering the idea of self-replicating systems and machines in the 1940/s. Originally, he considered actual robots, who could build other robots that could build other robots.
