Meeting Joost

1. Volgende stappen die nodig zijn voor een artikel.

   

Planning

Task #	Description	Action Items	Owner
1	Optimize functions	Compare the speed aspects of the calculation objective value after programming remarks.	Witek
2	Numerieke experimenten	XGBoost: Ordinal: Cardinal: Not working. Sampling strategy? Feature engineering?	Witek
3	Impact initial solution on local search	Experiment with various parameter values. Evaluate whether the previously found “dome shape” with peak is also valid under other settings. Erlang distribution	Witek Joost
4	Onderzoek een functionele vorm die de structuur omvat en de mogelijkheid tot een bewijs van submodulariteit.	Find a functional form that describes the structure. Analyze whether Ger’s papers on submodularity are applicable in this context. Document any proofs or insights.	Witek
5	Model \[\underset{M, a}{\operatorname{arg\,max}}f(M,a) \rightarrow Objective\ value\]	Train an XGBoost model for \(f(M, a\)). Focus on a simpler XGBoost model that targets the typical optimal structure (provided that 1a demonstrates this structure). Conduct accuracy tests for the XGBoost model that predicts \(f(M, a)\). Analyze and document the performance on the new dataset.	Witek

2. Benut informatie over shape voor local search

3. Ger: kijk naar 2^e afgeleide.
