Finite-Sample Coverage Audits for High-Recall Candidate Generation: Certification and Learning-Theoretic Design
Martin Anthony, Kaveh Salehzadeh Nobari
An initial high-recall stage in an empirical pipeline decides which items pass to later review, labelling, or modelling, and relevant items it misses are lost to every subsequent s…
Generalised Eigenvalue Geometry of Semantic Adversarial Attacks
Martin Anthony, Kaveh Salehzadeh Nobari
Recent empirical work shows that semantically equivalent paraphrases can fool financial sentiment classifiers: although a paraphrase remains close to the original under a strong re…
Sharp Hybrid Confidence Bands for Partially Identified Treatment Effects under Tail Uncertainty with an Application to Workforce Gender Diversity and Firm Performance
Grace Lordan, Kaveh Salehzadeh Nobari
Manski's nonparametric bounds partially identify the average treatment effects (ATEs) under minimal assumptions, yielding an interval-valued estimand with endpoints that depend on…
-Regularized Generalized Least Squares
Kaveh S. Nobari, Alex Gibberd
We study an -regularized generalized least-squares (GLS) estimator for high-dimensional regressions with autocorrelated errors. Specifically, we consider the case where e…
Pair copula constructions of point-optimal sign-based tests for predictive linear and nonlinear regressions
Kaveh Salehzadeh Nobari
We propose pair copula constructed point-optimal sign tests in the context of linear and nonlinear predictive regressions with endogenous, persistent regressors, and disturbances e…
