ML
- Kernel Regularized Least Squares (KRLS) as a hierarchical model and made tractable using random sketching
 - Foster-Warmuth Regression: better basis regressions for outcome modelling (and hence CATE estimation)
 - Debiased LASSO with general gaussian designs
 - Debiasing regularized regression estimators without well behaved covariance matrix
 - Tractable sum of squares approximations for \(f-\) divergences
 - Optimal Subgroup selection: identifying a region of the feature space where the regression function exceeds a threshold (wlog 0) as a constrained optimisation problem
