Algorithm 这里直接给出完整的核心集构建算法,贪心稀疏随机变分推断算法。 就是前面几节的综合。 粗略的看了下后面几节,第4节是信息几何框架下的理论推导,第5节是若干个实验,我主要只是想简单了解下贝叶斯视角的核心集算法,就先不看了。 杂谈 想好好看一遍本文的契机是之前在做一个用到coreset的主动学习项目,想着...

(RDSF); the former is an acceleration procedure based on a simple theoretical observation on using Uniform Random Sampling for clustering problems, the latter is a coreset-based data-summarising framework that builds on ACvS and extends it by using a regression algorithm as part of the ...
We employ LLMs to generate high-level embeddings that guide the evolutionary algorithm in selecting coresets, thus preserving the most important information while reducing the dataset size. Additionally, we introduce a gradient-based forgetting mechanism to further refine the coreset by eliminating ...
Our idea is inspired by the\ngreedy method, Gonzalez's algorithm, for solving the problem of ordinary\n$k$-center clustering. Based on some novel observations, we show that this\ngreedy strategy actually can handle $k$-center clustering with outliers\nefficiently, in terms of clustering ...
A core parameter in greedy coreset sampling is the sampling rate, denoted as p in Section 4.2. The fundamental objective for its employment is to efficiently yet effectively represent the data distribution with a minimal set of representative samples. This is achieved by a greedy algorithm that ai...
In parallel with CoreTemp, we design a fast match algorithm where the combination shows robust performance in open-set mobile biometrics authentication. Designed to resemble the effects of ensembles with marginal increment in computation, we propose PIEformer+, where its application with CoreTemp has...
