PIG: Parallel Inconsistency Guidance for Accelerating Diffusion Language Models

Quentin Fruytier, Anton Xue, Sanjay Shakkottai +1

Diffusion language models accelerate generation by decoding multiple masked positions per forward pass. However, accuracy is known to drop when parallel decoding trajectories devia…

LESSER: Post-Training Data Selection with Output-Layer Gradients

Lyuxin David Zhang, Eric Wong, Surbhi Goel +1

The choice of post-training data for large language models substantially affects downstream performance. Gradient-based data selection is a popular approach that ranks training dat…

dQwen3.5: Hybrid-Attention Diffusion Language Models

Anton Xue, Litu Rout, Aditya Akella +3

Adapting a pretrained autoregressive (AR) model is a cost-efficient route to a diffusion language model (DLM). While nearly all such adaptations start from a full-attention transfo…

Missingness Bias Calibration in Feature Attribution Explanations

Shailesh Sridhar, Anton Xue, Eric Wong

Popular explanation methods often produce unreliable feature importance scores due to missingness bias, a systematic distortion that arises when models are probed with ablated, out…

AnCoder: Anchored Code Generation via Discrete Diffusion Models

Anton Xue, Litu Rout, Constantine Caramanis +1

Diffusion language models offer a compelling alternative to autoregressive code generation, enabling global planning and iterative refinement of complex program logic. However, exi…

T-FIX: Text-Based Explanations with Features Interpretable to eXperts

Shreya Havaldar, Weiqiu You, Chaehyeon Kim +12

As LLMs are deployed in knowledge-intensive settings (e.g., surgery, astronomy, therapy), users are often domain experts who expect not just answers, but explanations that mirror p…

Probabilistic Soundness Guarantees in LLM Reasoning Chains

Weiqiu You, Anton Xue, Shreya Havaldar +4

In reasoning chains generated by large language models (LLMs), initial errors often propagate and undermine the reliability of the final conclusion. Current LLM-based error detecti…

Probabilistic Stability Guarantees for Feature Attributions

Helen Jin, Anton Xue, Weiqiu You +2

Stability guarantees have emerged as a principled way to evaluate feature attributions, but existing certification methods rely on heavily smoothed classifiers and often produce co…

AR-Pro: Counterfactual Explanations for Anomaly Repair with Formal Properties

Xiayan Ji, Anton Xue, Eric Wong +2

Anomaly detection is widely used for identifying critical errors and suspicious behaviors, but current methods lack interpretability. We leverage common properties of existing meth…

The FIX Benchmark: Extracting Features Interpretable to eXperts

Helen Jin, Shreya Havaldar, Chaehyeon Kim +10

Feature-based methods are commonly used to explain model predictions, but these methods often implicitly assume that interpretable features are readily available. However, this is…
