How do I use this parameter? When I run I do not get any halving at all at a setting of 2. My tuning works through the trials sequentially. I thought it would try and only carry forward the most promising combinations of hyper parameters.
Am I missing something, documentation seems thin on this setting IMHO
Thanks in advance,
Hey, I was facing this problem as well and still am not really sure what this param was supposed to be exactly due to the very limited docs.
This is what I found from ray tune faqs, hope it helps.
‘reduction_factor=4` means that only 25% of all trials are kept each time they are reduced.’
It does thanks for that clarification!
