Ranking Features to Promote Diversity: An Approach Based on Sparse Distance Correlation

Abstract

The improvement of sensing technology enables the collection of multiple process variables during product fabrication. This paper introduces a feature ranking scheme based on sparse distance correlation (SpaDC) that promotes diversity and assesses general dependency between process features and the quality variable. Theoretical properties, simulation studies, and real-case applications in semiconductor manufacturing demonstrate the effectiveness of the SpaDC method.
