In this run Clause_isOfType_screen was ok and others reduced in performance, to eventually hit zero performance meaning that the hmean divides by zero, producing the nan I think.
I then ran it again and this time it reached the end without turning to nan/coverging on zero performance, but it did have erratic jumps where when training on the same data it would fall quite dramatically for different predictions. I’m including two examples below:
