Ben, you haven't given us an update on how things are going with the Novamente A.I. engine lately. Is this because progress has been slow and there is nothing much to report, or you don't want to get peoples hopes up while you are still so far from being done, or that you want to surprise

[agi] Update on Novamente progress

2003-12-24 Thread Ben Goertzel
Hi Mike, About Novamente project progress... The reason I haven't given progress updates to this list lately is that I've been even more insanely busy than usual, due to a combination of AI work and (Novamente-related) business work and personal-life developments. So recreational

Brad, Hmmm... yeah, the problem you describe is actually an implementation issue, which is irrelevant to whether one does synchronoous or asynchronous updating. It's easy to use a software design where, when a neuron sends activation to another neuron, a check is done as to whether the target

Guess I'm too used to more biophysical models in which that approach won't work. In the models I've used (which I understand aren't relevant to your approach) you can't afford to ignore a neuron or its synapses because they are under threshold. Interesting dynamics are occurring even when the

Yep, you're right of course. The trick I described is workable only for simplified formal NN models, and for formal-NN-like systems such as Webmind. It doesn't work for neural nets that more closely simulate physiology, and it also isn't relevant to systems like Novamente that are less NN-like
