DeepEMD: Differentiable Earth Mover's Distance for Few-Shot Learning

2022 · IEEE Transactions on Pattern Analysis and Machine Intelligence

In this work, we develop methods for few-shot image classification from a new perspective of optimal matching between image regions. We employ the Earth Mover's Distance (EMD) as a metric to compute a structural distance …

Primacy Effect of ChatGPT

2023

Instruction-tuned large language models (LLMs), such as ChatGPT, have led to promising zero-shot performance in discriminative natural language understanding (NLU) tasks. This involves querying the LLM using a prompt containing the question, and the candidate …

DRS: Deep Question Reformulation With Structured Output

2025

Question answering represents a core capability of large language models (LLMs).However, when individuals encounter unfamiliar knowledge in texts, they often formulate questions that the text itself cannot answer due to insufficient understanding of the underlying …
