I'm trying to understand the behavior of the positive_replacement_decay and read_replacement_decay parameters in the [recommend.replacement] section.
In docs explain about Replacement but I'm a little confuse
If increase positive_replacement_decay closer to 1, will an item that has received positive feedback move up in the recommendation list or down?
Similarly, if I increase read_replacement_decay closer to 1, will an item that has been "read" (but hasn't received a positive reaction) stay higher in the recommendation list or move down?
[recommend.replacement]
# Replace historical items back to recommendations. The default value is false.enable_replacement = true# Decay the weights of replaced items from positive feedbacks. The default value is 0.8.positive_replacement_decay = 0.2# Decay the weights of replaced items from read feedbacks. The default value is 0.6.read_replacement_decay = 0.8
From what I understand based on the documentation, it seems that increasing positive_replacement_decay towards 1 will push positively reacted items up in the recommendation list, and increasing read_replacement_decay towards 1 will help "read" items maintain their higher order in the list. Could you confirm if this interpretation is correct?
