Nonparametric estimation of conditional VaR and expected shortfall
Z Cai, X Wang - Journal of Econometrics, 2008 - Elsevier
This paper considers a new nonparametric estimation of conditional value-at-risk and
expected shortfall functions. Conditional value-at-risk is estimated by inverting the weighted …

Learning to (learn at test time)
We reformulate the problem of supervised learning as learning to learn with two nested
loops (ie learning problems). The inner loop learns on each individual instance with self …
