  • Slides here

  • DLM: Slide5, Objective function compared to 1.3.0, can be different depending on the number of molecules.

  • CBy: What’s the difference in run1 & run2.

  • TG: Run1 was a bit buggy. But, the take away is that I am doing better in run2.

  • CBy: Slide8, from the table you exclude the r3-r3 bonds with smarts pattern and the description is saying to keep r3-r3 bonds?

  • TG: The generic parent parameter keeps whatever left. I am inverting the process of smarts pattern hierarchy.

  • CaB: So, it all depends on the training set, right?

  • TG: Yeah.

  • CB: The splits decrease the objective fn, and has less number of parameters than 1.3.0, so does this improve our FF?

  • TG: I will look into that.

  • CC: So the patterns are generated per step?

  • TG: Yeah.

  • CB: So, when you have the smarts pattern, it excludes things, but I can’t see the hierarchy from the table.
    Why ring4 bonds before ring3? This is still a bit puzzling.

  • TG: Okay, I will get back with more details.
