  Pedantic - UCI engines Author: JoAnn D. Peeler Rating Chess Engines Diary CEDR=3123 v.2.1.0: This release of Pedantic changes the architecture of the NNUE network from (768 -> 128) x 2 -> 1 to (768 -> 384) x 2 -> 1. It was built up in stages from 160, 192, 256 to 384 hidden layers with each step generating new training data for the next net. The final net was trained with 1.9 billion positions. Additionally, the inference was changed from using CReLu to SCReLu activation. Although in my last release I stated that I would endeavor to add HCE back into the engine, I have decided to abandon this as I will probably be ramping down my chess programming activities over the next several months.
