Numerical Embeddings for CTR Prediction: A Taxonomy, Unified Benchmark, and Open-Source FuxiCTR Extension
Heng Yao, Hanwei Zhu, Tianying Liu +2
Numerical embeddings map scalar features into vectors before a click-through rate (CTR) backbone combines the fields. To our knowledge, NumEmbBench is the first open benchmark dedi…

ScalarLens: Numerical Embeddings with Stable Coordinates and Contextual Responses for CTR Prediction
Heng Yao, Tianying Liu, Yulou Shu +6
Numerical embeddings for click-through rate (CTR) prediction are built on a convenient but restrictive premise: a scalar has one representation. This premise conflates where a valu…
