Ep 109: An experiment in fuzzy logic

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. Today, we have an informal experiment that shows why fuzzy logic is needed for even simple things.

Here’s an introductory video on fuzzy logic.

And here’s a detailed tutorial on fuzzy logic and its application.

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. It’s called an AI winter. Despite such setbacks, the general trend has been toward increasing ability and complexity within AI systems. Spring is coming, and maybe, it’s already here.

Adding by subtracting

There won’t be posts after this one on this thing for a couple of weeks. I must navigate the dangerous, relative infested waters of the holidays.

I need to be able to show that the way we program our machine can be made to run any program, at least in principle. On the other hand, I’d very much like to switch gear, and get to talking about gear soon.

Here’s one more post on using subleq. I think that will do for now.

Ep 106: The perceptron

Ep 106: The perceptron

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, and made over inflated statements about what his perceptron would be able to do. After the 1969 publication of Marvin Minsky and Seymour Papert’s book, “Perceptron,” which debunked many of Rosenblatt’s claims and pointed out some of the inherent limitations of the perceptron algorithm, interest and funding for neural networks dropped drastically.

Here are a couple of articles about the perceptron and the early history of neural network design.

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, mutate, self-replicate, and evolve in strange and wonderful ways.

Here’s the home page for Tierra.

Here’s a good article about Tierra.

And here’s a nice video on the Tierra system, and the story behind its creation.

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.

Here’s a beginner’s guide to redcode

Here is a link to a page that has html versions of the original scientific American articles that introduced the game.
