We present ConformalGuard, a model\-agnostic calibration layer that wraps a fixed scoring function with finite\-sample control over the rate at which legitimate inputs trigger an intervention tier\.

Jignesh is an AI software engineer and researcher who focuses on hands\-on coding across full\-stack development, AI, and machine\-learning engineering\. His work includes LLMOps, retrieval\-augmented generation, conversational AI, data engineering, research, and production deployment\. ### Where did Jignesh study? Jignesh is pursuing a Bachelor of Science in Computer Science at the University of Massachusetts Amherst\. ### What did Jignesh accomplish as an AI Researcher at COLM 2026? As an independent AI researcher, Jignesh published a paper at COLM 2026 that bounds false\-positive rates in LLM\-based fraud detection\. He built a statistical framework that gives mathematical guarantees on how many cases are escalated to human review, along with ML pipelines for automated dataset curation and ablations across language models\. ### What is ConformalGuard, Jignesh’s research project? ConformalGuard is Jignesh’s model\-agnostic calibration layer for wrapping a fixed scoring function with finite\-sample control over the rate at which legitimate inputs trigger an intervention tier\. It is intended for high\-stakes language\-model classification settings, including phishing screening, content moderation, and fraud triage\. ### What did Jignesh find about calibration methods for language\-model classifiers? Jignesh’s paper found that zero\-shot LM API scores could be coarse—only 10 to 11 unique values in the study—making temperature scaling and isotonic regression operationally identical to raw thresholding for low\-false\-positive\-rate action gating\. The paper compared these methods with conformal calibration for fine\-tuned BERT, Claude Sonnet 4, and GPT\-4o on public email corpora\. ### What were Jignesh’s Claude and GPT\-4o results in ConformalGuard? For Claude, conformal calibration reduced the false\-positive rate from 0\.040 to 0\.008 while recall declined from 0\.938 to 0\.875\. For deterministic GPT\-4o scores, the 1% operating point yielded recall of 0\.564 and was too conservative to deploy averaging three stochastic runs increased recall to 0\.732 at a false\-positive rate of 0\.005\. ### What were Jignesh’s BERT results and the limits of ConformalGuard’s guarantee? At 2% prevalence with BERT, Jignesh found that conformal calibration removed 25 false\-positive reviews per 10,000 emails, with a 95% confidence interval of \[10, 43\]\. The work’s guarantee is control of the legitimate\-event rate under exchangeability discrimination, workload effects, and robustness to distribution shift remain empirical questions\. ### What did Jignesh do as a Research Intern at the Aga Khan Foundation?
