Pea 2.0 what's new?

Second generation has been trained with 50 million positions generated with gen 1 networks.
These are the results vs the previous generation:
Net 0

Results of NET0gen2 vs NET0gen1 (5+0.1, 1t, 256MB, book.epd):  
Elo: inf +/- nan, nElo: inf +/- nan  
Games: 294, Wins: 294, Losses: 0, Draws: 0, Points: 294.0 (100.00 %)  
Net 1

Results of NET1gen2 vs NET1gen1 (5+0.1, 1t, 256MB, book.epd):  
Elo: 916.01 +/- nan, nElo: 2653.29 +/- 39.71  
Games: 294, Wins: 292, Losses: 1, Draws: 1, Points: 292.5 (99.49 %)  
I let both networks play a match vs Stash v9 to get a real elo estimate. This resulted in a rating of approximately 1138 for Net 0 and 1257 for Net 1. They are not strong but fun to play against as they have their own (bad) ideas.
