Learning to Simulate: Generative Metamodeling via Quantile Regression

no code implementations29 Nov 2023 L. Jeff Hong, Yanxi Hou, Qingkai Zhang, Xiaowei Zhang

In this paper, we propose a new metamodeling concept, called generative metamodeling, which aims to construct a "fast simulator of the simulator".

Clustering by the Probability Distributions from Extreme Value Theory

1 code implementation20 Feb 2022 Sixiao Zheng, Ke Fan, Yanxi Hou, Jianfeng Feng, Yanwei Fu

In contrast, the GPD fits the distribution of distance to the centroid exceeding a sufficiently large threshold, leading to a more stable performance of GPD k-means.

Incrementally Zero-Shot Detection by an Extreme Value Analyzer

no code implementations23 Mar 2021 Sixiao Zheng, Yanwei Fu, Yanxi Hou

However, zero-shot learning models assume that all seen classes should be known beforehand, while incremental learning models cannot recognize unseen classes.

Extreme Value k-means Clustering

no code implementations25 Sep 2019 Sixiao Zheng, Yanxi Hou, Yanwei Fu, Jianfeng Feng

We thus propose a novel algorithm called Extreme Value k-means (EV k-means), including GEV k-means and GPD k-means.
