[DL-Learner discussion] Learning A Super Class

[Steve H. <sho...@cr...>]

Hello All,

I’d like to learn a particular sequence of numbers. I’m using this pattern:  http://ceur-ws.org/Vol-216/submission_12.pdf to create class expressions that describe sequences. I’ve created a number of example sequences and would like to learn the expression that captures them all: eg given 4123, 1235, 123, etc and some negative examples, I’d like to learn the class expression for a list containing sequence 1,2,3. This task would essentially find the superclass for the positive examples (a list containing 1,2,3).

The DL learner examples I’ve come across use individuals for positive and negative inputs, but is there any reason classes couldn’t be used? I’ve tried this and eventually run out of heap space with 1.5 G RAM – but wonder if there is anything intrinsically wrong with this approach. I’ve also given each class a named individual and made the individuals the positive and negative examples. But, DL Learner also eventually runs out of heap space.

Thanks in advance for the help,
Steve
