Summary

NSPIN is a neurosymbolic framework that constructs probabilistic planning domain models for complex procedures like surgery directly from unstructured clinical narratives. It combines LLM-based text extraction and imputation with empirical validation to formalize surgical workflows.

This research introduces NSPIN, a neurosymbolic framework designed to create formal planning domain models from unstructured clinical narratives, specifically focusing on complex surgical procedures. The challenge lies in the lack of structured data and the implicit nature of actions described in medical texts, which neither purely symbolic methods nor large language models (LLMs) can fully address alone. NSPIN tackles this by first using a pretrained LLM to extract and infer structured event sequences from raw text. It then induces a Probabilistic Planning Domain Definition Language (PPDDL) model. The framework refines the preconditions of this model using LLM-proposed revisions, which are then empirically validated. The approach was tested on 2,660 laparoscopic appendectomy notes from nine surgeons, demonstrating that NSPIN generates models that generalize well to new data and whose induced knowledge aligns with expert surgical practice.

Why it matters

Formalizing complex medical workflows is crucial for decision support systems and training. This approach offers a way to leverage vast amounts of unstructured clinical data to build actionable, interpretable models, potentially improving patient safety and operational efficiency.

How to implement this in your domain

  1. 1Explore the potential of neurosymbolic AI for extracting structured knowledge from unstructured domain-specific texts.
  2. 2Identify complex operational workflows in your organization that could benefit from formal planning models.
  3. 3Pilot an LLM-driven data extraction and imputation process on a subset of relevant narrative data.
  4. 4Collaborate with domain experts to validate and refine the extracted knowledge and planning models.
  5. 5Investigate integrating such models into decision support tools or training simulations.

Harmony Improves Protein-Ligand Flexible Docking with Torsional Diffusion

Researchers introduce Harmony, a harmonic torsional diffusion framework for flexible protein-ligand docking that explicitly accounts for the periodic geometry of angular variables. This method improves ligand pose accuracy and pocket all-atom reconstruction on benchmarks like PDBBind and enhances the physical validity of generated complexes on PoseBusters.

Multilingual Verifier Bias Impacts RLVR in LLM Mathematical Reasoning

A study reveals that exact-match verifiers in Reinforcement Learning with Verifiable Rewards (RLVR) for Large Language Models (LLMs) exhibit significant language-dependent false-negative reward noise in multilingual mathematical reasoning. This bias, particularly pronounced in Japanese, stems from format and script variations, highlighting a cross-lingual selection bottleneck that impedes effective multilingual LLM training.

TriPLU Improves Tiny Language Model Performance with Trilinear Product FFNs

Researchers introduce TriPLU, a Trilinear Product Linear Unit, which replaces gated FFNs in tiny decoder-only language models with a direct degree-3 product branch. This approach achieves better validation loss on character-level TinyStories and lower bits per byte on other datasets under low-learning-rate settings, suggesting benefits for small models in specific low-compute regimes.
