Online Pen TestingITCS 20232023-01-10
Defines an online “pen testing” model where testing reduces an option’s value by threshold theta and passing reveals only residual value; proves a universal…

Estimation Beyond the IID Setting (Two Vignettes)Algorithmic Advances for Statistical Inference with Combinatorial Structure2021-10-11
Two vignettes show concrete claims and tools: the worst‑case squared‑error estimator for a coin with one flip predicts quarter/three-quarters rule and for k…

Charting the Landscape of Memory/Data Tradeoffs in Continuous Optimization: ...Rigorous Evidence for Information-Computation Trade-offs2021-09-13
Constrained-memory algorithms either store a basis or pay huge sample costs: over F2, algorithms with <~d^2/4 bits of memory require exponentially many samples…
