📄 Description

Draft: Alternative Normalization Scheme for Reranking

This submission presents a draft of a normalization scheme more suitable for reranking tasks.

Notably, this implementation replaces the original Min-Max normalization (which maps scores to the 0~1.0 range) with sigmoid normalization. The sigmoid function (1 / (1 + e^(-x))) is applied to each score to achieve the 0-1 range mapping.

Important note: This change will have a significant impact on API numerical values that currently return results in the (0,1) range. Therefore, this draft is not recommended for merging at this stage.
