In addition, we show that for 2 of these measures there are simple, strong plug-in estimators that require only the estimation of a conditional mean.

Originally developed for imputing missing entries in low rank, or approximately low rank matrices, matrix completion has proven widely effective in many problems where there is no reason to assume low-dimensional linear structure in the underlying matrix, as would be imposed by rank constraints.

Neural networks have seen limited use in prediction for high-dimensional data with small sample sizes, because they tend to overfit and require tuning many more hyperparameters than existing off-the-shelf machine learning methods.

Successful deployment of machine learning algorithms in healthcare requires careful assessments of their performance and safety.

Though black-box predictors are state-of-the-art for many complex tasks, they often fail to properly quantify predictive uncertainty and may provide inappropriate predictions for unfamiliar data.

We establish that the fitted models are Lipschitz in the penalty parameters and thus our oracle inequalities apply.

In predictive modeling applications, it is often of interest to determine the relative contribution of subsets of features in explaining the variability of an outcome.

In addition, we characterize the statistical convergence of the penalized empirical risk minimizer to the optimal neural network: we show that the excess risk of this penalized estimator only grows with the logarithm of the number of input features; and we show that the weights of irrelevant features converge to zero.

It is more efficient to tune parameters if the gradient can be determined, but this is often difficult for problems with non-smooth penalty functions.

We further establish minimax rates for a large class of sparse additive models.

We consider the task of fitting a regression model involving interactions among a potentially large set of covariates, in which we wish to enforce strong heredity.

We consider the problem of predicting an outcome variable using $p$ covariates that are measured on $n$ independent observations, in the setting in which flexible and interpretable fits are desirable.

Many authors have proposed methods to reduce the effects of selection bias under the assumption that the naive estimates of the effect sizes are independent.

With recent advances in high throughput technology, researchers often find themselves running a large number of hypothesis tests (thousands+) and esti- mating a large number of effect-sizes.
