A Comparative Assessment of Multi-view fusion learning for Crop Classification

1 code implementation10 Aug 2023 Francisco Mena, Diego Arenas, Marlon Nuske, Andreas Dengel

Instead, we present a comparison of multi-view fusion methods for three different datasets and show that, depending on the test region, different methods obtain the best performance.

On the Quality of Deep Representations for Kepler Light Curves Using Variational Auto-Encoders

1 code implementation Signal 2021 Francisco Mena, Patricio Olivares, Margarita Bugueño, Gabriel Molina, Mauricio Aray

In addition, the S-VRAE𝑡 embeds the re-scaling preprocessing of the time series into the model in order to use the Flux standard deviation in the learning of the light curves structure.

Self-Supervised Bernoulli Autoencoders for Semi-Supervised Hashing

1 code implementation17 Jul 2020 Ricardo Ñanculef, Francisco Mena, Antonio Macaluso, Stefano Lodi, Claudio Sartori

This paper investigates the robustness of hashing methods based on variational autoencoders to the lack of supervision, focusing on two semi-supervised approaches currently in use.
