Small monotonic regularization usually gets best results, but training with small monotonic regularization can be hard to guarantee monotonicity. We suggest to loop over random seeds before increasing monotonic regularization to get the best monotonic neural network.
-
The network structure is slightly modified compared to the ones in the paper. The networks in this repo have less parameters but similar performance.
