Ep 116: Bit seat drivers - The Lab
January 10, 2018

Bit seat drivers - Deep learning algorithms, and neural networks in general, require much more training than humans do. They are unable to generalize well enough to handle situations not covered in the training data,

Ep 115: do we need something else, or just more? - The Lab
January 09, 2018

do we need something else, or just more? - Though deep learning has had some promising results, there are still some things that it simply doesn’t do well at. There are other algorithms that do as well or better at certain tasks. On the other hand,

Ep 114: Use of graphics cards for neural networks - The Lab
December 29, 2017

Use of graphics cards for neural networks - Your graphics card holds a GPU—graphics processing unit. Unlike your CPU, which does one operation at a time, the GPU does many simple operations on many numbers at once.

Ep 113: Diving into deep learning - The Lab
December 28, 2017

Diving into deep learning - Neural networks have had their ups and downs. However, in the last decade or so, they’ve really taken off. There were a couple of breakthroughs that made all the difference. Today we look at one of them,

Ep 112: Evolving neural networks with polyworld - The Lab
December 27, 2017

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,

Ep 111: Unsupervised learning - The Lab
December 26, 2017

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.

Ep 110: Better and better - The Lab
December 22, 2017

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.

Ep 109: An experiment in fuzzy logic - The Lab
December 21, 2017

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.

Ep 108: Socrates is not a woman - The Lab
December 20, 2017

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.

Ep 107: Take heart, yee robots shivering in the cold - The Lab
December 19, 2017

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.
