Yes, the swarm picked a ScalarEncoder, but I wonder why it didn't pick the
AdaptiveScalarEncoder or the RDSE. I'm not very familiar with swarms, so
I'm not sure. When I tried to replace the "ScalarEncoder" in the
model_params.py file with "RandomDistributedScalarEncoder", I got this
message:
Error in constructing RandomDistributedScalarEncoder encoder. Possibly
missing some required constructor parameters. Parameters that were provided
are: {'maxval': 1.0, 'name': 'sine', 'minval': -1.0, 'clipInput': True,
'n': 427, 'w': 21}
It worked ok when I used "AdaptiveScalarEncoder", however, so this makes me
wonder if the swarming process will include the RDSE as a possibility or
not?
