The thesis explores Introspective Uncertainty Estimation (IUE) for large language models (LLMs) in code generation, aiming to determine whether hidden-state representations can indicate functional correctness at both response and line levels. Using LiveCodeBench and BigCodeBench, the study finds that hidden states provide a strong signal for overall correctness, with static single-token probes performing best, while dynamic strategies offer no consistent advantage. Although line-level fault localization is more challenging, a conditional Top‑K ranking approach remains effective, suggesting a two‑stage workflow that first screens responses for risk and then prioritizes line‑level checks.

Large Language Models (LLMs) are evolving from simple code completion tools to repository‑scale agents capable of retrieving context, editing files, executing tools, and engaging in security‑sensitive workflows. A structured survey up to May 31 2026 reviews LLM work across software engineering and security tasks, adaptation mechanisms, artifact granularity, and evaluation design, and introduces an assurance framework that separates functional correctness, security, operational reliability, evidence provenance, and agent authority. The review highlights that while execution feedback and repository access improve engineering task completion, they do not guarantee security, and static‑analysis labels rarely ensure deployable correctness; it also identifies common validity threats and proposes a minimum reporting protocol and a research agenda focused on jointly secure‑and‑functional benchmarks, repository‑scale threat models, calibrated human oversight, longitudinal maintainability evidence, and reproducible agent evaluation.

The paper investigates how to improve confidence calibration for large language models (LLMs) used in automated code revision (ACR). It proposes applying local Platt-scaling to three fine-grained confidence scores, rather than the conventional global method, and demonstrates that this approach consistently reduces calibration error across multiple tasks, metrics, and model sizes. The study shows that fine-grained calibration, especially when combined with global scaling, yields more reliable confidence estimates for ACR tasks.

This paper presents a black-box evaluation framework to systematically assess the ability of Large Language Models (LLMs) to generate Design Structure Matrices (DSMs) from structured technical documentation. Motivated by the closed-source nature of current Auto-DSM pipelines, the framework introduces a reproducible methodology that benchmarks generated DSMs (GEN-DSMs) against manually validated ground-truth matrices (GT-DSMs).
