[DL-Learner discussion] Stop running DL-Learner (CELOE/class expression learning algorithm) after generating n result

[Sarker, Md K. <sar...@wr...>]

Dear Concern,

With due respect, I am using Dl-Learner for class expression generation from positive and negative instances with respect to background ontology.


Particularly I am using CELOE algorithm.


I have some questions about running time:


The configurable parameters of CELOE algorithm (https://github.com/SmartDataAnalytics/DL-Learner/blob/develop/interfaces/doc/configOptions.txt) shows how to stop it after running maxExecutionTimeInSeconds time.

DL-Learner - A tool for supervised Machine Learning in OWL and Description Logics



But I am particularly interested to get top n results and then stop the program.


There are another  parameter maxNrOfResults  but if I run the algorithm for couple of minutes it does not generate the n result and stops based on maxExecutionTimeInSeconds.


1. Is there any way to produce top n result and stop the algorithm disregards of maxExecutionTimeInSeconds time?

2. How to speed up the algorithm? I know reasoning algorithms are in exponential complexity but is there any option to use multiple threads or parallelization or other configurable parameters which can speed up the execution time?


DL-Learner is an excellent tool. I appreciate the researcher's behind this tool.
