Summary
This study introduces a novel computational framework that converts complex single-cell data into testable biological hypotheses. The method uses decision trees and large language models to uncover new cellular mechanisms and regulatory logic.
Area of Science:
- Computational Biology
- Genomics
- Systems Biology
Background:
- Single-cell multimodal omics provide high-resolution cellular network data.
- Translating computational findings into testable biological mechanisms is challenging.
Purpose of the Study:
- To develop an analytical pipeline for discretizing continuous neural network attributions into regulatory thresholds.
- To enable large language models to synthesize context-specific hypotheses by integrating literature and empirical data.
Main Methods:
- Employing decision trees to discretize continuous neural network attributions.
- Structuring large language models with regulatory thresholds derived from data.
- Applying a continuous-to-discrete framework to sparse single-cell datasets.
Main Results:
- Identified a cytoskeletal gating hierarchy in EGF-stimulated pathways.
- Discovered transcriptomic drivers of input resistance in cortical interneurons.
- Delineated translational logic predicting Ki-67 abundance in spatial transcriptomics.
Conclusions:
- The framework successfully reconstructs published regulatory logic.
- Establishes an auditable methodology for extracting robust hypotheses from high-dimensional single-cell data.
- Facilitates hypothesis generation using an open-weight language model and a code-free interface.
