HyperNP: Interactive Visual Exploration of Multidimensional Projection Hyperparameters

no code implementations25 Jun 2021 Gabriel Appleby, Mateus Espadoto, Rui Chen, Samuel Goree, Alexandru Telea, Erik W Anderson, Remco Chang

Projection algorithms such as t-SNE or UMAP are useful for the visualization of high dimensional data, but depend on hyperparameters which must be tuned carefully.

Self-supervised Learning for Astronomical Image Classification

no code implementations23 Apr 2020 Ana Martinazzo, Mateus Espadoto, Nina S. T. Hirata

In Astronomy, a huge amount of image data is generated daily by photometric surveys, which scan the sky to collect data from stars, galaxies and other celestial objects.

Deep Learning Multidimensional Projections

no code implementations21 Feb 2019 Mateus Espadoto, Nina S. T. Hirata, Alexandru C. Telea

We train a deep neural network based on a collection of samples from a given data universe, and their corresponding projections, and next use the network to infer projections of data from the same, or similar, universes.
