OpenCog and Google Summer of Code 2009
Posted by: dhart on: 2009-03-25
We are happy to announce that the SIAI has been selected again this year to participate in the Google Summer of Code program as a mentoring organization. GSoC is an annual program that awards successful student contributors a 4500 USD summer stipend to work on open source and free software projects for three months. Around [...]
Fun with first-order inference

Joel Pitt has done some experiments testing first-order PLN inference in OpenCog, on some very simple data.
These experiments don’t use the indefinite probability formulas but rather the good old fashioned SimpleTruthValue PLN formulas.
What they involve is using PLN to extrapolate indirect word associations, from direct words associations mined from text (by some statistical text mining [...]
OpenCog Google-Summer-Of-Code Roundup
Posted by: bgoertzel on: 2008-09-05
This summer OpenCog was chosen by Google to participate in the Google Summer of Code project: Google funded 11 students from around the world to work on OpenCog coding projects under the supervision of experienced mentors associated with the OpenCog project, and the associated OpenBiomind project
Applying for GSoC was David Hart’s idea originally; and, David [...]
OpenCogPrime Tutorial Chat Sessions beginning September 2008
Posted by: bgoertzel on: 2008-08-10
I have decided to run a series of IRC sessions focused on collectively discussing the OpenCogPrime design, via working through the OpenCogPrime wikibook and discussing the ideas therein chapter-by-chapter.
Details are at http://opencog.org/wiki/OpenCogPrime:TutorialSessions
The sessions will be weekly and will start September 10 (I’ll be out of town the first week of Sep, and figure too many [...]

The purpose of this blog post is to announce the release of a wikibook outlining a design for a specific AGI system intended to be built on top of the OpenCog framework.
This system design is called OpenCogPrime, and is heavily based on the Novamente Cognition Engine design under development at Novamente LLC during 2001-2008.
The OpenCogPrime [...]
Spaced repetition and memory

An article in Wired from a while back on Piotr Wozniak (no relation to Steve), a researcher of optimal memory and learning strategies, got me thinking about learning theory and memorization in the context of OpenCog. From the article (emphasis mine):
Long-term memory, the Bjorks said, can be characterized by two components, which they named retrieval [...]
New importance spread system
Posted by: ferrouswheel on: 2008-07-06
Well, I’d noticed it’s been a while since we’ve had a post here and thought I’d rectify it with a brief note of what I’ve been up to. Posts of more substance are on their way I promise!
Recently we’ve been trying to play with some new mechanisms for the spread of Short Term Importance in [...]
Hopfield network example
Posted by: ferrouswheel on: 2008-06-08
As a toy problem for playing/testing/understanding attention allocation in OpenCog, I’ve been emulating the behaviour of a Hopfield network within the OpenCog AtomSpace.
For those not already aware, a Hopfield network is a kind of recurrent neural network that acts as an associative memory. It consist of a number of units linked together. These units store [...]
scheme shell
Posted by: linasv on: 2008-05-27
I needed the ability to hand-edit opencog data while other processes were running. And so I hacked with guile for a while, and now there’s a scheme shell for opencog.
So far it’s very simple: just say ’scm’ at the opencog prompt; this puts you into the shell. Then you can scheme away.
So, fore example:
(cog-new-node ‘ConceptNode [...]
