Causal feature selection framework for stable soft sensor modeling based on time-delayed cross mapping
DOI:10.1016/j.aei.2026.104337.png)
Abstract
En 中文
• Varying causal strength across time delay is considered for feature selection. • State space reconstruction is employed to deal with interdependent variables. • Time-delayed partial cross mapping is proposed for direct causal inference. • Features are selected automatically via causal strength and validation performance. • Features selected by direct causality can enhance model stability.
