Test-Time Scaling with Reflective Generative Model

ICLR 2026poster

We introduce a new Reflective Generative Model (RGM), which obtains OpenAI o3-mini's performance via a novel Reflective Generative Form. This form focuses on high-quality reasoning trajectory selection and contains two novelties: 1) A unified interface for policy and process reward model: we share t…

GRIP: A Graph-Based Reasoning Instruction Producer

NeurIPS 2025poster

Large-scale, high-quality data is essential for advancing the reasoning capabilities of large language models (LLMs). As publicly available Internet data becomes increasingly scarce, synthetic data has emerged as a crucial research direction. However, existing data synthesis methods often suffer fro…

OTE: Exploring Accurate Scene Text Recognition Using One Token

CVPR 2024poster

In this paper we propose a novel framework to fully exploit the potential of a single vector for scene text recognition (STR). Different from previous sequence-to-sequence methods that rely on a sequence of visual tokens to represent scene text images we prove that just one token is enough to charac…

Self-Supervised Pre-training with Symmetric Superimposition Modeling for Scene Text Recognition

IJCAI 2024poster

In text recognition, self-supervised pre-training emerges as a good solution to reduce dependence on expansive annotated real data. Previous studies primarily focus on local visual representation by leveraging mask image modeling or sequence contrastive learning. However, they omit modeling the ling…

Exploring Stroke-Level Modifications for Scene Text Editing

AAAI 2023technical

Scene text editing (STE) aims to replace text with the desired one while preserving background and styles of the original text. However, due to the complicated background textures and various text styles, existing methods fall short in generating clear and legible edited text images. In this study,…

Linguistic More: Taking a Further Step toward Efficient and Accurate Scene Text Recognition

IJCAI 2023poster

Vision model have gained increasing attention due to their simplicity and efficiency in Scene Text Recognition (STR) task. However, due to lacking the perception of linguistic knowledge and information, recent vision models suffer from two problems: (1) the pure vision-based query results in attenti…
