Evolving neural networks with polyworld - Figuring out exactly what structure of a neural network could capture intelligence is a complicated problem. Why not let evolution do it for you? Today we look at Polyworld,

Unsupervised learning - When you are teaching an AI to solve a problem or do some task, you usually have to provide the right answer. However, sometimes, the AI can learn by itself, without being told what the right answer is.

Better and better - Computers are being used to design computers. The better our computers and their tools get, the better computers and tools they can produce. But it wasn’t always an easy path. Today we look at the VAX9000.

An experiment in fuzzy logic - Computers use Boolean logic. Everything is true false, yes no, zero and one. There are plenty of situations when a simple yes or no won’t cover it. To get a computer to handle those situations, one can use fuzzy logic.

Socrates is not a woman - Evolutionary approaches, genetic algorithms, and neural networks aren’t the only approaches to creating artificial intelligence. Today, we look at one of the early and rather successful approaches—expert systems.

Take heart, yee robots shivering in the cold - In the past, new methods of creating an artificial intelligence have garnered interest and enthusiasm. Then, when the over optimistic forecasts fail, nearly all funding and research grinds to a halt.

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,
