青年学者学术沙龙causal inference and stable learning-j9登录网址

摘 要：

machine learning methods have demonstrated great success in many fields, but most of them are lack of interpretability and stability. causal inference is a powerful modeling tool for explanatory analysis, which might enable current machine learning to make an explainable and stable prediction. in this talk, we will show some new challenges of estimating causal effect in the wild big data scenarios, including (1) high dimensional and noisy variables, and (2) differentiation among variables. to address these challenges, we proposed data-driven variable decomposition (d2vd) and differentiated confounder balancing (dcb) algorithms. moreover, by marrying causal inference with machine learning, we proposed a causal regularizer to recover the causations between predictors and response variable and designed a stable learning algorithm for stable prediction across unknown testing data.
