Latest 100 papers on interpretability: Aug. 25, 2025

The quest for interpretability in AI and ML has never been more critical. As models grow in complexity and pervade high-stakes domains like healthcare and finance, understanding why they make decisions is as important as what decisions they make. This digest dives into recent breakthroughs, showcasing how researchers are illuminating the black box, from medical diagnostics to large language model (LLM) reasoning and beyond.## The Big Idea(s) & Core Innovationsits heart, recent research is tackling the interpretability challenge through diverse yet interconnected avenues: physics-informed models, structured reasoning, attention mechanism analysis, and novel explanation frameworks. medical signal processing, the paper, “Physics-Based Explainable AI for ECG Segmentation: A Lightweight Model” by Muhammad Fathur Rohman Sidiq and colleagues from Brawijaya University, introduces physics-based preprocessing (e.g., Hilbert Transform, FFT) for ECG segmentation. This inherently interpretable approach significantly boosts accuracy and provides a deeper understanding of feature extraction. Similarly, in “Versatile Cardiovascular Signal Generation with a Unified Diffusion Transformer“, Zehua Chen et al. from Tsinghua University present UniCardio, a diffusion transformer for multi-modal cardiovascular signal generation. Their method leverages complementary signals (PPG, ECG, BP) for robust synthesis, where generated signals match ground-truth performance in detecting health conditions, offering high interpretability.LLMs, the focus is on understanding and enhancing their reasoning. “A Review of Developmental Interpretability in Large Language Models” by Ihor Kendiukhov (Eberhard Karls University of Tübingen) emphasizes a developmental perspective, drawing parallels between human cognitive development and LLM learning to monitor and align capabilities. Building on this, “Non-Iterative Symbolic-Aided Chain-of-Thought for Logical Reasoning” by Phuong Minh Nguyen et al. from Japan Advanced Institute of Science and Technology, enhances LLM logical reasoning by integrating lightweight symbolic structures into prompts, making the reasoning process more transparent. Reilly Haskins and Benjamin Adams from the University of Canterbury, in their work “KEA Explain: Explanations of Hallucinations using Graph Kernel Analysis“, address LLM hallucinations using a neurosymbolic framework with graph kernels to not only detect but explain why a statement is hallucinated and what facts would make it correct.the realm of model security and robustness, M. Abu Baker and L. Babu-Saheer (Anglia Ruskin University) explore “Mechanistic Exploration of Backdoored Large Language Model Attention Patterns“. They reveal that backdoors leave detectable signatures in attention mechanisms, providing a path for detection. Complementing this, research on “Compressed Models are NOT Trust-equivalent to Their Large Counterparts” by Rohit Raj Rai et al. (IIT Guwahati) challenges the assumption that performance parity guarantees trust-equivalence in compressed models, highlighting the critical roles of interpretability alignment and calibration similarity.various domains, novel architectures and frameworks are emerging. “Tree-like Pairwise Interaction Networks” by Ronald Richman et al. (InsureAI, University of the Witwatersrand) introduces PINs for tabular data, explicitly modeling pairwise feature interactions for high accuracy and efficient SHAP value computation. In healthcare, “IPGPhormer: Interpretable Pathology Graph-Transformer for Survival Analysis” by Guo Tang et al. (Harbin Institute of Technology), provides interpretable cancer risk prediction at both tissue and cellular levels without post-hoc annotations.## Under the Hood: Models, Datasets, & Benchmarksadvancements are underpinned by new models, datasets, and rigorous evaluation methodologies:Deep-DxSearch: An end-to-end agentic RAG system for medical diagnosis, featuring the largest curated medical retrieval corpus (disease guidelines, patient records, clinical knowledge) to date.

(Paper)## Impact & The Road Aheadcollective thrust of this research is clear: to move beyond opaque, black-box AI towards systems that are not only powerful but also transparent and trustworthy. This shift has profound implications across industries. In healthcare, explainable AI (XAI) is bridging the gap between AI-driven diagnoses and clinical trust, as seen in ECG analysis with models like AICRN and physics-constrained PET imaging (PET-DPC), or in pathology with Ano-NAViLa and IPGPhormer. The ability to interpret why a model predicts a certain disease or identifies a specific region of interest is paramount for adoption by medical professionals.*natural language processing**, the focus on LLM interpretability is crucial for refining reasoning, detecting hallucinations, and ensuring safety. Frameworks like Symbolic-Aided CoT and KEA Explain are making LLM decisions more understandable and rectifiable. The exploration of developmental interpretability signals a long-term vision for building more aligned and predictable AI.*financial modeling and cybersecurity**, where stakes are incredibly high, interpretability translates directly into reliability and auditability. Frameworks like AlphaEval for alpha mining, TS-Agent for financial time-series modeling, and Trans-XFed for supply chain credit assessment are designed with transparency in mind, enabling better risk management and compliance. In cybersecurity, the need for robust and interpretable malware detection, as explored in “On the Consistency of GNN Explanations for Malware Detection“, is key to building resilient systems.specific applications, the meta-research on interpretability itself is evolving. Papers like “Prediction is not Explanation: Revisiting the Explanatory Capacity of Mapping Embeddings” remind us that high predictive accuracy doesn’t automatically equate to meaningful explanations, urging a more nuanced understanding of what “explainable” truly means. The emergence of general frameworks like Conformalized EMM and ITL-LIME further democratizes XAI by making sophisticated interpretability tools accessible across diverse models and data settings.road ahead is exciting. We anticipate a future where AI systems are not just intelligent but also wise – capable of explaining their reasoning, adapting to human feedback, and operating with a built-in sense of transparency. This collective push for interpretability is not merely an academic pursuit; it’s a fundamental step toward building a more responsible and trustworthy AI ecosystem for everyone.
