• Confidence-Controlled XAI Auditing for Pedestrian Detection under Domain Shift

  Ruben Dario Florez-Zela · 5. Oktober 2026

  Explainability is increasingly required for perception models in intelligent vehicles, yet whether explanations remain faithful under driving domain shift is still poorly understood. This work audits post-hoc explanations of a fixed YOLOv8s pedestrian detector across PIE and JAAD using ROI-based D-D…

• Beyond Trained Models: Compiling GNNs for a Sound Explainer Benchmark

  Steve Azzolin, Francesco Paolo Nerini, Stefano Teso, Francesco Bonchi, Bruno Lepri, Andr\'e Panisson, Andrea Passerini · 5. Oktober 2026

  Explainers for Graph Neural Networks (GNNs) are commonly evaluated by their plausibility, i.e., how well their explanations recover a predefined ground truth, such as a motif planted in the data. This protocol implicitly assumes that a GNN trained on such data relies on the intended motif. Although …

• MEA: A Reward-Driven Multi-Agent System for Faithful Model Explanations

  Yuyang Cheng, Raghav Kaushik Ravi, Srivarshinee Sridhar, Sriparna Saha, Akash Ghosh, Chirag Agarwal · 5. Oktober 2026

  Recent years have seen the employment of a plethora of machine learning (ML) models in high-stakes domains, but they remain largely opaque to the practitioners who act on their predictions. While post-hoc explanation methods offer a lens into this model behavior, wielding them effectively demands ex…

• How the Audit Rule Shapes Faithful Factor Explanations in LLMs

  Taolin Zhang, Hanyu Wang, Jiuheng Wan, Tingyuan Hu, Chengyu Wang · 2. Oktober 2026

  Large language models are often asked which input factors influenced their outputs. For structured inputs, such reports can be checked by counterfactual perturbation, but each factor must be queried multiple times to estimate its effect, so verification is usually budget-limited. We study how this l…

• Compliant AI Infrastructure for Regulated Finance: A tiered multi-agent framework with DLT audit trails for financial operations in DACH

  Walter Kurz, Reinhard Magg · 2. Oktober 2026

  We present a compliance-first architecture for AI in regulated finance that treats regulation as an orientation layer rather than a deterministic ruleset. A matrix of regulatory intent and exposure provides a compact classification handle, which a governed policy compiler then maps into concrete pro…

• MCIR: A Feature Dependence-Aware Explainability Method with Reliability Guarantees

  Poushali Sengupta, Sabita Maharjan, Frank Eliassen, Shashi Raj Pandey, Yan Zhang · 2. Oktober 2026

  Modern machine-learning models often contain strongly dependent or redundant features, making feature attribution difficult because shared predictive information can be distributed across correlated predictors. Existing methods such as SHAP, LIME, HSIC, MI/CMI, and SAGE may therefore produce unstabl…

• Permutation-Robust Decision Modeling with Candidate-Independent Block-Causal Attention

  Guy Amit · 2. Oktober 2026

  Decision models often score a variable-sized set of candidate actions encoded in a single sequence. This setting is increasingly relevant for System 1 components inside generative systems, where candidates may be proposed or ordered differently across runs. Standard causal cross-encoding is expressi…

• A Comparative Explainability Framework for DeBERTa-v3 in Zero-Shot Medical Abstract Classification

  Javier Diaz Esteban-Herreros, David Mu\~noz-Valero, Raquel Mart\'inez-Espa\~na, Jose M. Juarez, Juan Moreno-Garcia · 2. Oktober 2026

  A comparative explainability framework is presented to audit DeBERTa-v3 under zero-shot classification of medical abstracts. The work addresses the disagreement problem in Explainable Artificial Intelligence, where different attribution methods produce divergent explanations for the same input and p…

• Auditing Routing Entropy as an Uncertainty Signal in Attention-Residual Transformers

  Wenhao Liang, Lin Yue, Wei Emma Zhang, Mingyu Guo, Olaf Maennel, Weitong Chen · 2. Oktober 2026

  Dynamic architectures leave a per-example routing trace beside each prediction, and diffuse routing is easy to read as a sign that the prediction is unreliable. We audit that reading for routing entropy in Attention-Residual (AR) variants of Swin-Tiny and DeiT-Small, trained from scratch on CIFAR-10…

• Out-of-Distribution Detection using Counterfactual Distance

  Maria Stoica, Francesco Leofante, Alessio Lomuscio · 1. Oktober 2026

  Accurate and explainable out-of-distribution (OOD) detection is required to use machine learning systems safely. Previous work has shown that feature distance to decision boundaries can be used to identify OOD data effectively. In this paper, we build on this intuition and propose a post-hoc OOD det…

• Where MLLMs Fail and Why: Causal Task Decomposition for Capability Failure Diagnosis

  Xia Hu, Brian Potetz, Chun-Ta Lu, Huanfen Yao, Leonidas Guibas, Zhicheng Wang, Howard Zhou, Pengfei Xing, Andrew Gallagher · 1. Oktober 2026

  End-to-end accuracy on compositional tasks records how often MLLMs fail, but cannot distinguish whether a failure reflects an intrinsic deficit in the targeted capability or a cascading error from an upstream prerequisite. We propose a causal decomposition framework that isolates these two failure m…

• Interpretable but Fragile? Robustness of Concept Bottlenecks under Geometric-Semantic Perturbations

  Hanwei Zhang, Tianma Hu, Gaojie Jin, Xu Cheng, Ronghui Mu · 1. Oktober 2026

  Concept Bottleneck Models (CBMs) are designed to provide interpretable intermediate representations, yet how such bottlenecks affect robustness remains unclear, with existing studies reporting mixed and sometimes contradictory findings. We argue that these discrepancies arise from conflating differe…

• Routing Probes Can Improve Without New Information: An Exact-Null Audit of Uncertainty Beyond Model Outputs

  Wenhao Liang, Lin Yue, Wei Emma Zhang, Mingyu Guo, Olaf Maennel, Weitong Chen · 1. Oktober 2026

  Routing signals of modern vision transformers -- expert gates, attention-residual weights and halting scores -- often improve probes that predict whether the model is correct, and the improvement is commonly read as evidence that routing carries information about errors beyond the model's outputs. W…

• When the Wrong Key Wins: Understanding and Detecting Hallucinations in LLMs

  Xuhan Tong, Haoyue Bai, Dawei Zhou, Naichen Shi, Jiawei Zhang · 30. September 2026

  Large language models can hallucinate even when the knowledge required for a correct answer is already available. We study this failure through a latent-key view of inference, where answer selection depends on competition among associations acquired during pretraining. We show that model predictions…

• Frontier Learning: Training LLM Reasoners at the Edge of Capability

  Robin Faro, Shyam Sundhar Ramesh, Ilija Bogunovic, Aurelien Lucchi · 30. September 2026

  Reinforcement Learning-based post-training of Large Language Models (LLM) has been successfully applied to improve their reasoning capabilities. Existing pipelines primarily finetune LLMs on a fixed pool of problems specified prior to training using the GRPO loss. This is fundamentally limiting, as …

• Beyond Verbalized Confidence: Calibrating Reasoners with Differentiable Readouts

  Chenxiao Fan, Chongming Gao, Gangyi Zhang, Leyang Shen, Yaxin Gong, Jiamin Wang, Jiakai Wang, Dong Wang, Yang Liu, Fuli Feng, Xiangnan He · 30. September 2026

  Reinforcement learning with verifiable rewards (RLVR) trains reasoning models to produce correct answers, but does not ensure that their stated confidence is calibrated. The resulting models are systematically overconfident. Recent methods train calibration inside the RLVR loop by having the model s…

• Steering Language Model Goals with Value Transplant

  Pengcheng Jiang, Fabien Roger · 30. September 2026

  Reasoning models often act as if they pursue goals, but their efforts are not always directed toward what users intend, sometimes leading them to pursue unintended outcomes. Previous work has examined how models may internally track their progress toward their goals through a "value axis." We study …

• From Input to Output: A Flexible Agent for Dual-End Interpretation of Sparse Autoencoder Features

  Dewen Liu, Zixuan Li, Jonathan Pan, Zhao Wu, Zijun Yao, Juanzi Li, Xiaozhi Wang · 30. September 2026

  Sparse autoencoders (SAEs) are an important tool for mechanistic interpretability, but interpreting their many features remains challenging. Existing methods characterize input-side activation patterns and output-side intervention effects, yet often leave their functional connection implicit, while …

• RewardExplainer: Learning Reward Model Explanations from Counterfactual Preference Feedback

  Jingyi He, Nier Wu, Shuang Liu, Xin Wang, Mengnan Du, Xia Hu · 30. September 2026

  Reward models (RMs) are a key component of large language model post-training, providing reward signals for subsequent reinforcement learning. However, conventional discriminative RMs typically output only scalar scores, making it difficult to identify the response behaviors associated with their sc…

• Gradients for Interventions and Activations for Detection: Targeted Feature Learning in Language Models

  Jonathan Drechsel, Steffen Herbold · 30. September 2026

  Model-internal features can be studied through both their ability to identify a specified concept and their causal effect when manipulated, e.g., through steering or weight editing. A prominent approach to feature learning is Sparse Autoencoders (SAEs), which learn broad feature dictionaries whose r…

• COLLATOR: Compositional Multi-Agent Orchestration with Counterfactual Reinforcement Learning

  Xudong Chen, Yixin Liu, Hua Wei, Kaize Ding · 30. September 2026

  Large language models (LLMs) provide a flexible foundation for multi-agent systems, but their effectiveness and computational cost depend critically on orchestration design. Across different tasks, role design, capacity assignment, and dependency construction jointly affect both solution quality and…

• The Unequal Influence of Bad Advice: Using Training Data Attribution to Modulate Emergent Misalignment

  Gon\c{c}alo Paulo, Louis Jaburi, Nora Belrose, Lucia Quirke, Stella Biderman · 30. September 2026

  Fine-tuning large language models on narrow, misaligned tasks can undo their post-training alignment and induce novel misaligned behaviors -- a phenomenon known as \emph{emergent misalignment} (EM). EM has been linked to persona-like representations, where fine-tuning might reduce loss by amplifying…

• Selecting The Most Informative Tokens in Natural Language Autoencoders

  Federico Torrielli, Gianluca Barmina, Andrea Blasi N\'u\~nez, Amon Rapp, Luigi Di Caro, Peter Schneider-Kamp, Lukas Galke Poech · 30. September 2026

  Natural language autoencoders translate a language model's internal activations into readable explanations. Explaining every token position is costly. Which positions should an auditor inspect to understand a potential threat? We study this question across $4.7$ million explanations on prompt inject…

• Active Budget Can Kill Sensitivity: Diagnosing and Repairing TopK Sparse Autoencoder Reliability

  Zhenting Huang, Junnan Liu, Qianren Mao, Zhixing Tan, Bo Jiang · 30. September 2026

  Sparse autoencoders (SAEs) are increasingly scaled to wider dictionaries to recover fine-grained structure from large language model activations. However, a feature is useful for interpretation only if it remains a stable unit of analysis when the same meaning is expressed in different surface forms…

• Representational Simplicity and Circuit Size Dissociate in a Threshold-Dependent Way: A Controlled Test via Adversarial Training

  Adam Elimadi · 30. September 2026

  Sparse-autoencoder decomposability and concentrated feature attribution are increasingly treated as evidence that a model's computation is easier to reverse-engineer. Whether this representational and attributional cleanliness actually predicts a smaller or more tractable causal circuit remains an o…
