ASSESS: A Semantic and Structural Evaluation Framework for Statement Similarity

ICLR 2026poster

Despite significant strides in statement autoformalization, a critical gap remains in the development of automated evaluation metrics capable of assessing formal translation quality. Existing metrics often fail to balance semantic and structural information: string-based methods neglect semantics, w…

Decompose, Structure, and Repair: A Neuro-Symbolic Framework for Autoformalization via Operator Trees

ICML 2026poster

Statement autoformalization acts as a critical bridge between human mathematics and formal mathematics by translating natural language problems into formal language. While prior works have focused on data synthesis and diverse training paradigms to optimize end-to-end Large Language Models (LLMs), t…

FormalRx: Rectify and eXamine Semantic Failures in Autoformalization

ICML 2026poster

Autoformalization—translating mathematical problems from natural language into formal proof assistant code—is essential for rigorous machine reasoning. However, existing evaluation frameworks provide only opaque binary verdicts or scalar scores, offering no interpretable insight into where or why tr…

UniSER: A Foundation Model for Unified Soft Effects Removal

CVPR 2026

Digital images are often degraded by soft effects such as lens flare, haze, shadows, and reflections, which reduce aesthetics even though the underlying pixels remain partially visible. The prevailing works address these degradations in isolation, developing highly specialized, specialist models tha

ATLAS: Autoformalizing Theorems through Lifting, Augmentation, and Synthesis of Data

NeurIPS 2025poster

Autoformalization, the automatic translation of mathematical content from natural language into machine-verifiable formal languages, has seen significant progress driven by advances in large language models (LLMs). Nonetheless, a primary barrier to further improvements is the limited availability of…

Adaptive Spatiotemporal Augmentation for Improving Dynamic Graph Learning

ICASSP 2025accepted

Dynamic graph augmentation is used to improve the performance of dynamic GNNs. Most methods assume temporal locality, meaning that recent edges are more influential than earlier edges. However, for temporal changes in edges caused by random noise, overemphasizing recent edges while neglecting earlie…

Interacted Object Grounding in Spatio-Temporal Human-Object Interactions

AAAI 2025technical

Spatio-temporal Human-Object Interaction (ST-HOI) understanding aims at detecting HOIs from videos, which is crucial for activity understanding. However, existing whole-body-object interaction video benchmarks overlook the truth that open-world objects are diverse, that is, they usually provide limi…

Layer- and Timestep-Adaptive Differentiable Token Compression Ratios for Efficient Diffusion Transformers

CVPR 2025poster

Diffusion Transformers (DiTs) have achieved state-of-the-art (SOTA) image generation quality but suffer from high latency and memory inefficiency, making them difficult to deploy on resource-constrained devices. One major efficiency bottleneck is that existing DiTs apply equal computation across all…

Anti-drifting Feature Selection via Deep Reinforcement Learning (Student Abstract)

AAAI 2023technical

Feature selection (FS) is a crucial procedure in machine learning pipelines for its significant benefits in removing data redundancy and mitigating model overfitting. Since concept drift is a widespread phenomenon in streaming data and could severely affect model performance, effective FS on concept…
