Key details

  • Conventional evaluation metrics offer only coarse measures of lexical overlap or entity matching and fail to reflect the granular diagnostic accuracy required for clinical use.
  • To address this gap, we propose CT-FineBench, a benchmark built from CT-RATE and Merlin to evaluate the fine-grained factual consistency of CT reports, constructed from CT-RATE and Merlin.
  • Our benchmark is constructed through a meticulous, Question-Answering (QA) based process: first, we identify and structure key, finding-specific clinical attributes (like location, size, margin).
  • Second, we systematically transform these attributes into a QA dataset, where questions probe for specific clinical details grounded in gold-standard reports.

arXiv:2604.25700v1 Announce Type: cross Abstract: Software quality assurance remains a major challenge in industrial environments, where large-scale and long-lived systems inevitably accumulate defects.

What's new

By relying only on textual information, our approach requires no access to source code, execution traces, or static analysis artifacts, making it directly deployable within existing industrial maintenance workflows.

Key details

  • Identifying the location of a fault is often time-consuming and costly, particularly during maintenance phases when developers must rely primarily on textual bug reports rather than complete runtime or code-level context.
  • In this study, we investigated if artificial intelligence can support fault localization using only the natural-language content of bug reports.
  • By relying only on textual information, our approach requires no access to source code, execution traces, or static analysis artifacts, making it directly deployable within existing industrial maintenance workflows.
  • We framed fault localization as a supervised text classification problem and evaluated three traditional machine learning models (Logistic Regression, Support Vector Machine, and Random Forest) and two fine-tuned transformer-based language models (RoBERTa-B...

arXiv:2603.16877v2 Announce Type: replace Abstract: Financial analysts face significant challenges extracting information from lengthy 10-K reports, which often exceed 100 pages.

What's new

Our findings emphasize the critical role of reranking in financial RAG systems and demonstrate performance improvements over baseline methods through modern language models and refined retrieval strategies.

Key details

  • This paper presents a Retrieval-Augmented Generation (RAG) system designed to answer questions about S&P 500 financial reports and evaluates the impact of neural reranking on system performance.
  • Our pipeline employs hybrid search combining full-text and semantic retrieval, followed by an optional reranking stage using a cross-encoder model.
  • We conduct systematic evaluation using the FinDER benchmark dataset, comprising 1,500 queries across five experimental groups.
  • Results demonstrate that reranking significantly improves answer quality, achieving 49.0 percent correctness for scores of 8 or above compared to 33.5 percent without reranking, representing a 15.5 percentage point improvement.

Summary: arXiv:2604.22837v1 Announce Type: cross Abstract: SAM-based dense trackers provide strong short-term mask propagation but remain fragile under long occlusion, fast motion.

  • What happened: arXiv:2604.22837v1 Announce Type: cross Abstract: SAM-based dense trackers provide strong short-term mask propagation but remain fragile under long occlusion, fast.
  • Why it matters: This report presents an occlusion- and reappearance-aware extension of DAM4SAM that improves memory control rather than changing the backbone.
  • What to do: Validate with one small internal benchmark and compare against your current baseline this week.
Deep

Context

The problem is especially severe for small objects, where a few incorrect memory updates can dominate later predictions.

What's new

The method augments the original SAM3 tracker with four ingredients: a reliability-aware tracking state machine, branch-based recovery, delayed DRM promotion, and a selective policy for native SAM3 memory selection.

Key details

  • The problem is especially severe for small objects, where a few incorrect memory updates can dominate later predictions.
  • This report presents an occlusion- and reappearance-aware extension of DAM4SAM that improves memory control rather than changing the backbone.
  • The method augments the original SAM3 tracker with four ingredients: a reliability-aware tracking state machine, branch-based recovery, delayed DRM promotion, and a selective policy for native SAM3 memory selection.
  • During stable tracking, the model follows the original single-path propagation process.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.

Wrap your compiled graph in one line, get policy enforcement (loops, budgets) and a local-first live dashboard with time-travel replay.

Key details

  • Wrap your compiled graph in one line, get policy enforcement (loops, budgets) and a local-first live dashboard with time-travel replay.
  • No SaaS, no signup, no telemetry leaving your machine.
  • As agents move from demos to production, three things bite: - Infinite loops — the agent ping-pongs between nodes, burning tokens silently.
  • - Runaway cost — one bad prompt eats your monthly OpenAI budget before you notice.
