Cluster Exploration using Informative Manifold Projections

no code implementations26 Sep 2023 Stavros Gerolymatos, Xenophon Evangelopoulos, Vladimir Gusev, John Y. Goulermas

Dimensionality reduction (DR) is one of the key tools for the visual exploration of high-dimensional data and uncovering its cluster structure in two- or three-dimensional spaces.

EgPDE-Net: Building Continuous Neural Networks for Time Series Prediction with Exogenous Variables

1 code implementation3 Aug 2022 Penglei Gao, Xi Yang, Rui Zhang, Ping Guo, John Y. Goulermas, Kaizhu Huang

While exogenous variables have a major impact on performance improvement in time series analysis, inter-series correlation and time dependence among them are rarely considered in the present continuous methods.

Entropic trust region for densest crystallographic symmetry group packings

no code implementations24 Feb 2022 Miloslav Torda, John Y. Goulermas, Roland Púček, Vitaliy Kurlin

Molecular crystal structure prediction (CSP) seeks the most stable periodic structure given the chemical composition of a molecule and pressure-temperature conditions.

Generalised Image Outpainting with U-Transformer

1 code implementation27 Jan 2022 Penglei Gao, Xi Yang, Rui Zhang, John Y. Goulermas, Yujie Geng, Yuyao Yan, Kaizhu Huang

In this paper, we develop a novel transformer-based generative adversarial neural network called U-Transformer for generalised image outpainting problem.

Discriminative Triad Matching and Reconstruction for Weakly Referring Expression Grounding

1 code implementation8 Jun 2021 MingJie Sun, Jimin Xiao, Eng Gee Lim, Si Liu, John Y. Goulermas

In this paper, we are tackling the weakly-supervised referring expression grounding task, for the localization of a referent object in an image according to a query sentence, where the mapping between image regions and queries are not available during the training stage.

Distributed Document and Phrase Co-embeddings for Descriptive Clustering

no code implementations EACL 2017 Motoki Sato, Austin J. Brockmeier, Georgios Kontonatsios, Tingting Mu, John Y. Goulermas, Jun{'}ichi Tsujii, Sophia Ananiadou

Descriptive document clustering aims to automatically discover groups of semantically related documents and to assign a meaningful label to characterise the content of each cluster.
