TS40K: a 3D Point Cloud Dataset of Rural Terrain and Electrical Transmission System

no code implementations22 May 2024 Diogo Lavado, Cláudia Soares, Alessandra Micheletti, Ricardo Santos, André Coelho, João Santos

This is not only a novel problem for the research community that can aid in the high-risk mission of power-grid inspection, but it also offers 3D point clouds with distinct characteristics from those in self-driving and indoor 3D data, such as high point-density and no occlusion.

Optimizing PatchCore for Few/many-shot Anomaly Detection

3 code implementations20 Jul 2023 João Santos, Triet Tran, Oliver Rippel

Exhaustive experiments on the public VisA and MVTec AD datasets reveal that (I) significant performance improvements can be realized by optimizing hyperparameters such as the underlying feature extractor, and that (II) image-level augmentations can, but are not guaranteed, to improve performance.

Evaluating Post-hoc Interpretability with Intrinsic Interpretability

no code implementations4 May 2023 José Pereira Amorim, Pedro Henriques Abreu, João Santos, Henning Müller

Despite Convolutional Neural Networks having reached human-level performance in some medical tasks, their clinical use has been hindered by their lack of interpretability.

Simplifying Multilingual News Clustering Through Projection From a Shared Space

no code implementations28 Apr 2022 João Santos, Afonso Mendes, Sebastião Miranda

Our system achieves state-of-the-art results on a multilingual news stream clustering dataset, and we introduce a new evaluation for zero-shot news clustering in multiple languages.
