GazeVLM: Active Vision via Internal Attention Control for Multimodal Reasoning

Human visual reasoning is governed by active vision, a process where meta-cognitive control drives top-down goal-directed attention, dynamically routing foveal focus toward task-relevant details while maintaining peripheral awareness of the global scene. In contrast, modern Vision-Language Models (VLMs) process visual...

Memory-Efficient Looped Transformer: Decoupling Compute from Memory in Looped Language Models

Recurrent LLM architectures have emerged as a promising approach for improving reasoning, as they enable multi-step computation in the embedding space without generating intermediate tokens. Models such as Ouro perform reasoning by iteratively updating internal representations while retaining a standard Key-Value (KV)...

MELD: Multi-Task Equilibrated Learning Detector for AI-Generated Text

MELD (Multi-Task Equilibrated Learning Detector), which instead trains on class-balanced, family-specific AI-versus-human tasks while sharing a common representation of human writing, and its prediction scores remain stable through 2022 and increase from 2023 onward, coinciding with the widespread adoption of LLM-based...

DRAGON: A Benchmark for Evidence-Grounded Visual Reasoning over Diagrams

The DRAGON dataset contains 11,664 annotated question instances from six diagram QA datasets, with a 2,445-instance test set carrying human-verified evidence annotations and a standardized evaluation framework, which supports future research on models that ground their predictions in visual evidence.

Demystifying the Unreasonable Effectiveness of Greedy Alignment Methods

Greedy AI alignment methods based on Bradley-Terry reward-model fitting and KL-regularized Alignment are remarkably effective in both offline and online preference-learning pipelines, yet existing O(log T) online and O(1/epsilon) offline KL-regularized regret rate guarantees can seem pessimistic relative to their empir...

HiFloat4 Format for Language Model Pre-training on Ascend NPUs

It is argued that numerical format design is itself a first-class lever for stable FP4 training, and the first systematic study of FP4 LLM pretraining on energy-efficient Huawei Ascend NPUs is presented.

EffiPair: Improving the Efficiency of LLM-generated Code with Differential Execution Feedback

EffiPair, a training-free, test-time framework that pairs structurally similar programs with different efficiencies, distills their relative execution behavior into compact feedback, and iteratively refines a candidate pool is demonstrated, demonstrating the effectiveness of relational execution feedback as a lightweig...

Relative Density Ratio Optimization for Stable and Statistically Consistent Model Alignment

The proposed alignment method is statistically consistent and yields significantly tighter convergence guarantees than DDRO, and is based on the relative density ratio between the preferred data distribution and a mixture of the preferred and non-preferred data distributions.

How Does"English (US)"Become the Default? Triangulating Structural Bias Towards American English Across the LLM Pipeline

This first rigorous pipeline-wide study of structural bias across major phases of LLM development shows that contemporary LLMs privilege AmE as the de facto norm, raising concerns about linguistic homogenization, epistemic injustice, and inequity in global AI deployment, while providing a rigorous basis for targeted co...

An Inspectable LLM Council for Multi-Model Research Answer Aggregation

This work presents an inspectable LLM Council with two synthesis stages: an analyst organizes three independent candidate answers into a structured textual state, and a separately invoked writer composes the final response from the question and that state.

Proof-based general-purpose computing with Magnetar

Zero-knowledge proofs can verify computing results without rerunning workloads or exposing sensitive data. Magnetar helps bring them into the mainstream with support for standard programming languages, major speed gains, and quantum-resistant security. The post Proof-based general-purpose computing with Magnetar appeared first on Microsoft Research.
