GReaTer: Gradients Over Reasoning Makes Smaller Language Models Strong Prompt Optimizers

ICLR 2025poster

The effectiveness of large language models (LLMs) is closely tied to the design of prompts, making prompt optimization essential for enhancing their performance across a wide range of tasks. Although recent advancements have focused on automating prompt engineering, many existing approaches rely exc…

HRScene: How Far Are VLMs from Effective High-Resolution Image Understanding?

ICCV 2025poster

High-resolution image (HRI) understanding aims to process images with a large number of pixels, such as pathological images and agricultural aerial images, both of which can exceed 1 million pixels. Vision Large Language Models (VLMs) can allegedly handle HRIs, however, there is a lack of a comprehe…

S3-DST: Structured Open-Domain Dialogue Segmentation and State Tracking in the Era of LLMs

ACL 2024findings

Traditional Dialogue State Tracking (DST) has focused on tracking preferences and intents in conversations centered around specific tasks (e.g. booking services). These conventional systems assume a relatively restricted conversation flow in which each turn gradually offers new information. However,…

CONTaiNER: Few-Shot Named Entity Recognition via Contrastive Learning

ACL 2022long

Named Entity Recognition (NER) in Few-Shot setting is imperative for entity tagging in low resource domains. Existing approaches only learn class-specific semantic features and intermediate representations from source domains. This affects generalizability to unseen target domains, resulting in subo…
