Before revision:  In our approach, the de-biasing is itself performed by machine learning, a variant called  de-biased machine learning via regularized Riesz representers (DML-RRR ). We prove our estimator is consistent, asymptotically normal, and semi-parametrically efficient.
After revision:  In our approach, the de-biasing is itself performed by machine learning, a variant called de-biased machine learning (Auto-DML ). We prove our estimator is consistent, asymptotically normal, and semi-parametrically efficient.
