Encog 2.0 for Java has been released. The beta test period is now over. To download Encog 2.0, visit http://www.encog.org. The forum contains more information on what will be added in Encog 2.1.

Encog 2.0 Dot Net has been released to beta test status

jeffheaton — Fri, 03 Jul 2009 14:50:07 +0000

Encog 2.0 adds many new features to the Encog API. Some of these include recurrent neural networks, RPROP training, advanced pruning, and many other features.

Encog 2.0 DotNet has been released as beta-1. I think its pretty solid, but, of course, let me know if you run into any issues. The download is here:

If you want the 2.0 workbench, just use the Java one. Its packaged as a windows executable, and reads/writes/generates all the same files that the C# version needs. Encog data files are the same between C# and Java.

Slides for Introduction to Encog

On June 2nd I gave a presentation to the Gateway Java Users Group that presented a brief introduction to the Encog AI Framework. I've posted the slides online here for any who wish to view them.

Are some companies easier to predict than others?

jeffheaton — Tue, 09 Jun 2009 03:22:19 +0000

To better test out Encog 2.0 on large training sets I am beginning to conduct research for predicting trends in the S&P 500 index. I am starting out simple just using historic price information to predict future trends. I will post this research, as it progresses, to the following URL:

There will also be forum posts as this progresses. The first experiment, which was just completed attempted to determine if some companies on the S&P were more predictable than others. You can see a chart of this training here:

Here is the official link from the Gateway Java users group on the Encog presentation that I will be giving. If you are in the St. Louis area, and are interested in Encog, this presentation will give an intro to Encog. I plan to post the material here once the presentation is complete.

Encog 2.0 Java Docs Posted

jeffheaton — Fri, 15 May 2009 12:19:20 +0000

The Java docs for Encog 2.0 have been posted. They are about 95% complete. Everything has documentation, I just plan to expand coverage on some of the class definitions. You can see the documentation here.

http://www.heatonresearch.com/javadoc/encog-2.0/index.html

Encog 2.0 beta will be released soon, for now you can download Encog 2.0 from the Heaton Research build server.

http://build.heatonresearch.com/

The C# side is still probably a few months away. Unfortunately, the C# side got fairly out of sync for this upgrade. And it is a major upgrade to Encog.

Feature List for Encog 2.0

jeffheaton — Thu, 14 May 2009 19:52:04 +0000

Encog 2.0 provides a much more flexible structure for representing and training neural networks. A feature list is presented here. Beta versions of Encog will go out in a few days for Java. DotNet, probably in a few months.

New Build Server for Encog

jeffheaton — Wed, 13 May 2009 23:43:02 +0000

A new build server has been added. This computer is responsible for all of the Encog builds. Currently it only handles the Java builds, but soon will handle the C#/DotNet builds as well. We have Cruise Control running on the server you can see it here.

http://build.heatonresearch.com/

If you would like to download the absolute latest build of Encog, this is the place. Of course the latest build is never as stable as our production releases. Currently, we are working on Encog 2.0, which is pretty stable. Defiantly beta quality. You can download the latest from the above page.
