Probing down to early cosmic epochs using limited redshift () optical surveys with host galaxy age and lookback time analysis
Siddharth Kasthurirangan, Meet Panchal, Aparna Joshi +1
We present a detailed analysis of AGN identification diagnostics and host galaxy evolution using optical spectral diagnostics using ESO-GOODS-S data. We employ traditional Baldwin-…
ShieldGemma 2: Robust and Tractable Image Content Moderation
Wenjun Zeng, Dana Kurniawan, Ryan Mullins +14
We introduce ShieldGemma 2, a 4B parameter image content moderation model built on Gemma 3. This model provides robust safety risk predictions across the following key harm categor…
Driver Age and Its Effect on Key Driving Metrics: Insights from Dynamic Vehicle Data
Aparna Joshi, Kojo Adugyamfi, Jennifer Merickel +2
By 2030, the senior population aged 65 and older is expected to increase by over 50%, significantly raising the number of older drivers on the road. Drivers over 70 face higher cra…
Debiasing Text Safety Classifiers through a Fairness-Aware Ensemble
Olivia Sturman, Aparna Joshi, Bhaktipriya Radharapu +2
Increasing use of large language models (LLMs) demand performant guardrails to ensure the safety of inputs and outputs of LLMs. When these safeguards are trained on imbalanced data…
Investigating Speed Deviation Patterns During Glucose Episodes: A Quantile Regression Approach
Aparna Joshi, Jennifer Merickel, Cyrus V. Desouza +3
Given the growing prevalence of diabetes, there has been significant interest in determining how diabetes affects instrumental daily functions, like driving. Complication of glucos…
