Deepdpm: Deep clustering with an unknown number of clusters

M Ronen, SE Finder, O Freifeld - Proceedings of the IEEE …, 2022 - openaccess.thecvf.com
Deep Learning (DL) has shown great promise in the unsupervised task of clustering. That
said, while in classical (ie, non-deep) clustering the benefits of the nonparametric approach …

A method for autonomous data partitioning

X Gu, PP Angelov, JC Príncipe - Information sciences, 2018 - Elsevier
In this paper, we propose a fully autonomous, local-modes-based data partitioning
algorithm, which is able to automatically recognize local maxima of the data density from …

A hierarchical distance-dependent bayesian model for event coreference resolution

B Yang, C Cardie, P Frazier - Transactions of the Association for …, 2015 - direct.mit.edu
We present a novel hierarchical distance-dependent Bayesian model for event coreference
resolution. While existing generative models for event coreference resolution are completely …

Powered dirichlet process for controlling the importance of" rich-get-richer" prior assumptions in bayesian clustering

G Poux-Médard, J Velcin, S Loudcher - arXiv preprint arXiv:2104.12485, 2021 - arxiv.org
One of the most used priors in Bayesian clustering is the Dirichlet prior. It can be expressed
as a Chinese Restaurant Process. This process allows nonparametric estimation of the …

Hnp3: A hierarchical nonparametric point process for modeling content diffusion over social media

SA Hosseini, A Khodadadi… - 2016 IEEE 16th …, 2016 - ieeexplore.ieee.org
This paper introduces a novel framework for modeling temporal events with complex
longitudinal dependency that are generated by dependent sources. This framework takes …

Powered Dirichlet process-controlling the “rich-get-richer” assumption in bayesian clustering

G Poux-Médard, J Velcin, S Loudcher - Joint European Conference on …, 2023 - Springer
The Dirichlet process is one of the most widely used priors in Bayesian clustering. This
process allows for a nonparametric estimation of the number of clusters when partitioning …

Reducing over-clustering via the powered Chinese restaurant process

J Lu, M Li, D Dunson - arXiv preprint arXiv:1802.05392, 2018 - arxiv.org
Dirichlet process mixture (DPM) models tend to produce many small clusters regardless of
whether they are needed to accurately characterize the data-this is particularly true for large …

[HTML][HTML] Cooperative hierarchical Dirichlet processes: Superposition vs. maximization

J Xuan, J Lu, G Zhang - Artificial Intelligence, 2019 - Elsevier
The cooperative hierarchical structure is a common and significant data structure observed
in, or adopted by, many research areas, such as: text mining (author–paper–word) and multi …

Hierarchical non‐parametric Markov random field for image segmentation

X Wang, J Zhao - IET Computer vision, 2017 - Wiley Online Library
Markov random fields (MRFs) are prominent in modelling image to handle image processing
problems. However, they confront the bottleneck of model selection in further improving the …
