Inspire: Benchmarking Scientific Literature Search for Open Research Problems

Jianrong Ding, Zhengyan Shi, Jianyuan Zhong +5

Scientific literature search often begins with an open research problem rather than a known target paper or a fixed candidate set. We introduce INSPIRE, a benchmark for evaluating…

FAME: Forecasting Academic Impact via Continuous-Time Manifold Evolution

Jianrong Ding, Jianyuan Zhong, Zhengyan Shi +1

Large Language Models (LLMs) are increasingly used to brainstorm and evaluate research ideas, yet assessing such judgments is fundamentally difficult because the true impact of a n…

Learning to Solve Complex Problems via Dataset Decomposition

Wanru Zhao, Lucas Caccia, Zhengyan Shi +3

Curriculum learning is a class of training strategies that organizes the data being exposed to a model by difficulty, gradually from simpler to more complex examples. This research…

Mixture of Noise for Pre-Trained Model-Based Class-Incremental Learning

Kai Jiang, Zhengyan Shi, Dell Zhang +2

Class Incremental Learning (CIL) aims to continuously learn new categories while retaining the knowledge of old ones. Pre-trained models (PTMs) show promising capabilities in CIL.…
