Experiment 20170215a-NOOR

Relaxation (80%) increases precision and reach consistency [[euzenat2017a]]
Results for addjoin and refadd are underestimated (see [20180311-NOOR])

Experiment design

DockerOS DockerEXP

Date: 20170215

Hypotheses: Introducing the capability for agent to sometimes ignore the most specific applicable correspondences (with given immediate consumption probability) will improve precision by fighting shadowing.

Variation of: 20170209-NOOR

4 agents; 10 runs; 10000 games

Adaptation operators: delete replace refine add addjoin refadd

Experimental setting: Repetition of [20170208-NOOR] and [20170209-NOOR] with consuption probability set to 80%

Compared 80% immediate consumption probability (20170215a-NOOR) to raw operators (20170214a-NOOR and 20170214b-NOOR):

  • In plain, raw operator semantic F-measure;
  • In dashed, 80% immediate consumption probability semantic F-measure.

(drawn from data scaled every 100 measures)


Key points

  • The results converge in all cases to 100% precision and 0% incoherence.
  • The behaviour of addjoin as related to add is still unclear
  • Recall and F-measure are however lower

Further experiments

  • sortout the add/addjoin discrepancy
  • associate it with the expansion operator (see 20170215b-NOOR)
