Yes, this sounds silly, doesn't it? Every user of moses has built some large, complex system around it to feed it tables of data and then to process other data using these outputs. Unfortunately, all of these are proprietary systems, but it occurs to me that maybe one of these could be open-sourced. I'll have to ask. The one I know best can take structured and unstructured data from a variety of sources, filter and process these into training-data sets, collect up a number of best-fit moses colbo results, average them together into an ensemble, and then output that as a data-processing pipeline: you feed it tables (or individual lines from tables) and it makes predictions based on that input. Practical experience shows that it is more-or-less comparable to "decision forests" (a decision forest being an ensemble of decision trees; a decision tree being kind-of-like a combo program but obtained from different algorithms). Both moses and decision-forests max out at a certain level of accuracy, beyond with it takes an ungodly amount of training time to improve on. There was a nascent effort to apply deep learning techniques, but it foundered on a lack of funding. I'm not sure I answered your question, but that's what I've got. -- Linas -- cassette tapes - analog TV - film cameras - you -- You received this message because you are subscribed to the Google Groups "opencog" group.
