Self-Regulating Cars: Automating Traffic Control in Free Flow Road Networks

AAAI 2026technical

Free-flow road networks, such as suburban highways, are increasingly experiencing traffic congestion due to growing commuter inflow and limited infrastructure. Traditional control mechanisms—traffic signals or local heuristics—are ineffective or infeasible in these high-speed, signal-free environmen

Designing Informative Metrics for Few-Shot Example Selection

ACL 2024findings

Pretrained language models (PLMs) have shown remarkable few-shot learning capabilities when provided with properly formatted examples. However, selecting the “best” examples remains an open challenge. We propose a complexity-based prompt selection approach for sequence tagging tasks. This approach a…

NaijaHate: Evaluating Hate Speech Detection on Nigerian Twitter Using Representative Data

ACL 2024long

To address the global issue of online hate, hate speech detection (HSD) systems are typically developed on datasets from the United States, thereby failing to generalize to English dialects from the Majority World. Furthermore, HSD models are often evaluated on non-representative samples, raising co…

CONTRA: Contrarian statistics for controlled variable selection

AISTATS 2021poster

The holdout randomization test (HRT) discovers a set of covariates most predictive of a response. Given the covariate distribution, HRTs can explicitly control the false discovery rate (FDR). However, if this distribution is unknown and must be estimated from data, HRTs can inflate the FDR. To allev…
