Joone 2.0.0 RC1 released

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! Read more...
  • 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 is out

The new neural network GUI editor - JoonePad - is out! Try it now by launching it directly from the web (You need JRE 1.5 and WebStart installed). Some of the new features:

  • Added a wizard to easily build several kinds of neural networks
  • Added a java code generator in order to reproduce in a custom java program the same network currently displayed in the editor
  • Now it's possible to import a neural network exported by the old GUI editor
  • The TODO-list now is an active list: click an item in order to highlight the corresponding component containing the error
  • Improved the user interface with docking panels and enhanced property sheets, in order to make it simpler to use the editor

This is a pre-view beta release, so please be patient if you discover some bug...

I want to thank Huascar Fiorletta for the great support and contribution he gave to make all that possible

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

The new Distributed Training Environment 0.8.0 released

The main features of this powerful framework for distributed processing of neural networks:

  • The training process scale almost linearly adding more machines
  • Possibility to add or remove machines dynamically during the training process
  • The overall process controlled by XML parameters
  • Latest SUN's Jini 2.0 compliant
  • Easily expandible with new features/algorithms/control modules, etc.

Joone 1.1.0 released

A new version of Joone is out! Great new features in this release:

  • Added the Resilient Backprop algorithm (RPROP), a really performant new training algorithm (thanks to Boris Jansen)
  • Improved the core engine's speed of about 35-40%, thanks to a deep review of the threads synchronization mechanism.

    On an Athlon 2200Mhz the XORMemory example took 4.4 sec to execute 10,000 epochs with the old 1.0.1 version; now it executes the same elaboration in only 2.4 seconds!

    Now the Joone's performances are nearly comparable to a C/C++ framework!
  • Added the setting of a http proxy to access to Internet also in presence of a firewall proxy
  • several bug fixes and a lot of small enhancements

New site Look&Feel

Thanks to the Forrest project, we have changed the look&feel of our web site. Now all the content is written in XML, and the HTML pages are obtained by applying a XSL transformation. By separating the content from the layout, we can easily and quickly add and modify the content, without affecting the graphical layout. Moreover, now all the pages are easily reachable from the menu on the left, and for each page is also available the content in PDF format.
