Robust effects of working memory demand during naturalistic language comprehension in language-selective cortex
Published 2023“…Further, these memory operations appear to be primarily carried out by the same neural resources that store linguistic knowledge, with no evidence of involvement of brain regions known to support working memory across domains.SIGNIFICANCE STATEMENT:This study uses fMRI to investigate signatures of working memory (WM) demand during naturalistic story listening, using a broad range of theoretically motivated estimates of WM demand. …”

Context and Participation in Machine Learning
Published 2023“…We first develop two frameworks that lend clarity to the human choices that shape ML systems and the broad populations that these systems affect. These inform a prospective question: how can we shape new systems from the start to reflect context-specific needs and benefit justice and equity? …”

Automated Data-driven Algorithm and Mechanism Design in Online Advertising Markets
Published 2023“…While autobidding significantly simplifies and scales up ad procurement processes, it also brings about new challenges: for advertisers, the simplification to ad procurement comes at the cost of information dilution as advertisers no longer have access to granular procurement details; for ad platforms, booming advertiser activities have incentivized growing sophistication in advertising campaign and objectives. …”

Geometry of Sensitivity: Twice Sampling and Hybrid Clipping in Differential Privacy with Optimal Gaussian Noise and Application to Deep Learning
Published 2023“…Our results are both negative and positive: on one hand, we show the curse of dimensionality is tight for a broad class of sensitivity sets satisfying certain symmetry properties; but if, fortunately, the representation of the sensitivity set is asymmetric on some group of orthogonal bases, we show the optimal noise bounds need not be explicitly dependent on either dimension or rank. …”
