Benchmark and application of unsupervised classification approaches for univariate data

open access: yesCommunications Physics, 2021
Unsupervised machine learning, and in particular data clustering, is a powerful approach for the analysis of datasets and identification of characteristic features occurring throughout a dataset. It is gaining popularity across scientific disciplines and

Adversarial Learning Approach to Unsupervised Labeling of Fine Art Paintings

open access: yesIEEE Access, 2021
An automatic classification of fine art images is limited by the scarcity of high-quality labels made by art experts. This study aims to provide meaningful automatic labeling of fine art paintings (machine labeling) without the need for human annotation.

Evaluating Unsupervised Text Classification: Zero-shot and Similarity-based Approaches [PDF]

open access: yesInternational Conference on Natural Language Processing and Information Retrieval, 2022
Text classification of unseen classes is a challenging Natural Language Processing task and is mainly attempted using two different types of approaches. Similarity-based approaches attempt to classify instances based on similarities between text document

Unsupervised Classification by Iterative Voting

open access: yesInternational Journal of Crowd Science, 2023
In the paper we present a simple algorithm for unsupervised classification of given items by a group of agents. The purpose of the algorithm is to provide fast and computationally light solutions of classification tasks by the randomly chosen agents. The

An Unsupervised Domain Adaptation Method Towards Multi-Level Features and Decision Boundaries for Cross-Scene Hyperspectral Image Classification

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Despite success in the same-scene hyperspectral image classification (HSIC), for the cross-scene classification, samples between source and target scenes are not drawn from the independent and identical distribution, resulting in significant performance ...

MetaAlign: Coordinating Domain Alignment and Classification for Unsupervised Domain Adaptation [PDF]

open access: yesComputer Vision and Pattern Recognition, 2021
For unsupervised domain adaptation (UDA), to alleviate the effect of domain shift, many approaches align the source and target domains in the feature space by adversarial learning or by explicitly aligning their statistics.

Interpretable and unsupervised phase classification

open access: yesPhysical Review Research, 2021
Fully automated classification methods that provide direct physical insights into phase diagrams are of current interest. Interpretable, i.e., fully explainable, methods are desired for which we understand why they yield a given phase classification ...

Self-supervised Regularization for Text Classification

open access: yesTransactions of the Association for Computational Linguistics, 2021
Text classification is a widely studied problem and has broad applications. In many real-world problems, the number of texts for training classification models is limited, which renders these models prone to overfitting.
