Survival of the Most Influential Prompts: Efficient Black-Box Prompt Search via Clustering and Pruning

Han Zhou, Xingchen Wan, Ivan Vulić +1

Prompt-based learning has been an effective paradigm for large pretrained language models (LLM), enabling few-shot or even zero-shot learning. Black-box prompt search has received…

Batch Calibration: Rethinking Calibration for In-Context Learning and Prompt Engineering

Han Zhou, Xingchen Wan, Lev Proleev +4

Prompting and in-context learning (ICL) have become efficient learning paradigms for large language models (LLMs). However, LLMs suffer from prompt brittleness and various bias fac…

Adaptive Batch Sizes for Active Learning A Probabilistic Numerics Approach

Masaki Adachi, Satoshi Hayakawa, Martin Jørgensen +4

Active learning parallelization is widely used, but typically relies on fixing the batch size throughout experimentation. This fixed approach is inefficient because of a dynamic tr…

Bayesian Optimisation of Functions on Graphs

Xingchen Wan, Pierre Osselin, Henry Kenlay +3

The increasing availability of graph-structured data motivates the task of optimising over functions defined on the node set of graphs. Traditional graph search algorithms can be a…

SimSC: A Simple Framework for Semantic Correspondence with Temperature Learning

Xinghui Li, Kai Han, Xingchen Wan +1

We propose SimSC, a remarkably simple framework, to address the problem of semantic matching only based on the feature backbone. We discover that when fine-tuning ImageNet pre-trai…

Universal Self-Adaptive Prompting

Xingchen Wan, Ruoxi Sun, Hootan Nakhost +4

A hallmark of modern large language models (LLMs) is their impressive general zero-shot and few-shot abilities, often elicited through in-context learning (ICL) via prompting. Howe…

Bayesian Quadrature for Neural Ensemble Search

Saad Hamid, Xingchen Wan, Martin Jørgensen +2

Ensembling can improve the performance of Neural Networks, but existing approaches struggle when the architecture likelihood surface has dispersed, narrow peaks. Furthermore, exist…
