| Parameter splitting progress and follow up from last meeting Recap of bit representation strategy for representing force field parameters slide 1: parameter splitting on real FF example slide 2: first example, turning off the hydrogen bit started with the one that had biggest contribution to gradient high regularization penalty doubts that it is realistic that CC and CO bonds are identical (colored orange) further splits split off different chemistry suggestion to parallelize a bit to speed up process general process is to run FB, split and run FB again
slide 3: unclear how gradient magnitude is affected by splitting regularization: L2 reg from FB L2 reg may not be in the obj and its grad, so that might explain strange behaviour of gradient along splitting
