Updates for 3.5

Thu, 08/06/2009 - 22:27 — amharrison

A new release is out that addresses the Eclipse 3.5 updates.

Installation Notes:

  • Categories do not work (for some reason). Turn off "group by category" and you'll see the jACT-R bundles.
  • Remote execution is unavailable for now. Enough has changed to the communications framework that 3.5 is incompatible.

New Features:

combined aural & visual

Wed, 06/17/2009 - 01:54 — amharrison

A new-ish release is out with the aural and visual modules that use a combined and generalized code base.

Swing Integration

Mon, 06/15/2009 - 22:14 — amharrison

Yes, it is being actively worked on. There is already some mostly functional code in the repository. A few more weekends of tweaks and improvements and we should have something that modelers can actually use!!

tainted release..

Wed, 02/18/2009 - 06:01 — amharrison

Apologies. Last week a tainted release made it out the door without my knowledge. Forgot to run the unit tests after fixing issues that FindBugs had found. Turns out one of them, wasn't a bug.. and produced some nasty results. So, if you've been running a model that was claiming a production couldn't be instantiated when you knew full well it could.. that was why. All is right with the universe again.

How do I connect a model to Java Swing/AWT?

Excellent question. Unfortunately, you can't yet. Not for any technical reasons. I'm just spread too thin with pieces that are more critical to my own research.

What does it take to hook them up? Ideally, there would be a swing sensor that would be responsible for parsing the visible GUI and generating percepts.

important update..

Sat, 01/17/2009 - 04:32 — amharrison

A new update is out today that makes the new motor system official. Prior releases using the new system had some hideous bugs associated with the timing of aborted movements. But with plenty of testing within the playerstage and robot interfaces, they seem to have been resolved.

This release also brings with it the ability to do longitudinal iterative runs (where the model learning is persisted across blocks of runs) - making for some interesting capabilities.

last-command

Tue, 01/06/2009 - 23:35 — amharrison

The last-command slot in buffer queries allows canonical lisp to see what the last request issued to a module was. Unfortunately, requests are not first-class model elements (can't be stored, retrieved, or even inspected), so !eval!s are required to make any significant sense of them.

General Probe

Tue, 12/16/2008 - 22:14 — amharrison

The general probe is a combination two tools that provides a general capacity to track arbitrary parameters over time. On the runtime side, org.jactr.tools.grapher.core.GeneralProbe selects model elements (productions, chunks, types, modules, buffers, etc), based on regular expression name matches (quick and easy to implement, but a little wonky if you don't know reg-ex), and attaches probes to them. The general probe then sends that data to the IDE where it is rendered in the jACT-R Probes view.  

Visicon Viewer

Tue, 12/16/2008 - 22:04 — amharrison

To help debug models that rely upon the visual system, jACT-R includes a graphical visicon viewer. It's a little rough around the edges right now, but it is certainly functional.

Using Visicon Viewer

To use, simply enable the visicon tracer in the run configuration for your model. Once the model starts, the visicon viewer (lower-left corner of the IDE) should be updated.

Tracers

Tue, 12/16/2008 - 15:13 — amharrison

Tracers are special instruments that have a GUI component installed in the IDE. These are a tad more complicated, but certainly within the realm of an experienced java programmer.
Tracers typically record and send massive amounts of data to the IDE, so care must be taken to handle the information in a responsive manner that doesn't make the IDE unusable.
