Nightly Builds available
In order to permit anyone interested to try the last build of the engine, starting from today we'll publish the nightly builds of the core engine.
Check periodically http://sourceforge.net/project/showfiles.php?group_id=22635&package_id=133185 in order to see if a new build is available.

Joone 2.0.0 RC1 released
Joone is a FREE neural net framework to create, train and test artificial neural networks. The aim is to create a powerful environment both for enthusiastic and professional users, based on the newest Java technologies.
Joone's neural networks can be built on a local machine, be trained on a distributed environment and run on whatever device.
Everyone can write new modules to implement new algorithms or new architectures starting from the simple components distributed with the core engine.
After a lot of months of hard work, the new Joone 2.0 is ready. This is a release candidate, so anyone is invited to try it and help us to discover any problem.
Some of the new features:
- The core engine has been refactored by adding the single-thread mode. The resulting performances are improved by 50%, with an enhanced reliability and scalability.
- A set of tools were added, in order to hide the complexity of the API, and make it very simple to work with the core engine. Now you can build, train and interrogate a neural network by writing only 3 rows of code!
- A new Image I/O component has been added, in order read and write directly from/to image files (jpeg and gif format supported)
- Added a new SoftMax Layer to build neural networks for resolving 1 of C classification problems
- Improved the usability of the property panels, by adopting a new file chooser panel, and a visual calendar panel in order to make it very simple to insert date fields
- Several bugs were fixed and the documentation has been updated with the new features

JoonePad 0.5.0 released
We're proud to announce the version 0.5.0 of JoonePad, the new visual editor of Joone that will substitute the actual JoonEdit.
The actual implemented feaures permit to:
* Build a new neural network by using a simple wizard
* Load a network exported (NOT saved) by the old JoonEdit application
* Display the visual representation of the network
* Edit all the properties of the Neural Network (like in the old Control Panel)
* Run/Stop/Continue the network training
* Export the neural network either in binary or XML format
* Generate the java source code needed to reproduce the edited network within a custom java program
* Select any item of the TODO-list in order to highlight the corresponding component containing the error
The new editor adopts a completely different approach to the definition of a neural network, because now it's available a wizard that drives the user step-by-step, in order to help him to build a new neural network from scratch.
Now you can open an exported neural network (from the old JoonEdit), and obtain the corresponding graphic representation in order to edit it.
Moreover, the new editor is built as an MDI application, so you can load and work on multiple networks at a time.
It is built by using the SwiXAT framework (http://www.swixat.org, another open source project maintained by P.Marrone, the author of Joone) and is just a beta release, as a lot of work has to be done.
We hope you'll appreciate the new approach.
You can launch it fron this URL: http://www.jooneworld.com/joonepad/ws/JoonePad.jnlp
(you need WebStart). If you want, you can also post your comments and suggestions at http://www.jooneworld.com/wiki/tiki-view_forum.php?forumId=2

Joone 1.2.1 released
Joone is a FREE neural net framework to create, train and test artificial neural networks. The aim is to create a powerful environment both for enthusiastic and professional users, based on the newest Java technologies.
Joone's neural networks can be built on a local machine, be trained on a distributed environment and run on whatever device.
Everyone can write new modules to implement new algorithms or new architectures starting from the simple components distributed with the core engine.
This is mainly bug fix release. Some of the new features:
* Added the support for the Groovy scripting language
* Added the LogarithmicPlugin to apply a logarithmic transformation (base e) to input data
* Added the save as XML in the GUI Editor
Several bugs were fixed:
* Fixed a problem that prevented the SangerSynapse from learning when in training mode
* Now the inspection panel doesn't show the biases for Layers for which this doesn't make sense
* Fixed the lacking of the first column when copied in the clipboard the inspected values
