Category Bias kNN

MAS — Fri, 09 Jun 2023 00:33:06 GMT

v16 has added an option to the k-Nearest Neighbor platform called Category Bias.

What is this? I can't find any specifics about this option in the documentation. And, importantly,

What numerical value should the Category Bias be set to in v16 to make the kNN results identical to those produced by v15 which does not have a Category Bias?

You can find out about Category Bias in the help documentation here.

"Category Bias

Specifies a tuning parameter that ensures that the fitted probabilities for categorical responses are always positive. By default, the Category Bias is 0.5."
