Text Clustering with Large Language Model Embeddings
Alina Petukhova, João P. Matos-Carvalho, Nuno Fachada
Text clustering is an important method for organising the increasing volume of digital content, aiding in the structuring and discovery of hidden patterns in uncategorised data. Th…
Multispectral Indices for Wildfire Management
Afonso Oliveira, João P. Matos-Carvalho, Filipe Moutinho +1
The increasing frequency and severity of wildfires necessitates advanced methods for effective surveillance and management, as traditional ground-based techniques often struggle to…
Generating Multidimensional Clusters With Support Lines
Nuno Fachada, Diogo de Andrade
Synthetic data is essential for assessing clustering techniques, complementing and extending real data, and allowing for more complete coverage of a given problem's space. In turn,…
MN-DS: A Multilabeled News Dataset for News Articles Hierarchical Classification
Alina Petukhova, Nuno Fachada
This article presents a dataset of 10,917 news articles with hierarchical news categories collected between 1 January 2019 and 31 December 2019. We manually labeled the articles ba…
Procedural Generation of 3D Maps with Snappable Meshes
Rafael C. e Silva, Nuno Fachada, Diogo de Andrade +1
In this paper we present a technique for procedurally generating 3D maps using a set of premade meshes which snap together based on designer-specified visual constraints. The propo…
