CoronaSurveys: Using Surveys with Indirect Reporting to Estimate the Incidence and Evolution of Epidemics
Oluwasegun Ojo, Augusto García-Agundez, Benjamin Girault +22
The world is suffering from a pandemic called COVID-19, caused by the SARS-CoV-2 virus. National governments have problems evaluating the reach of the epidemic, due to having limit…
Region adaptive graph fourier transform for 3d point clouds
Eduardo Pavez, Benjamin Girault, Antonio Ortega +1
We introduce the Region Adaptive Graph Fourier Transform (RA-GFT) for compression of 3D point cloud attributes. The RA-GFT is a multiresolution transform, formed by combining spati…
Graph Vertex Sampling with Arbitrary Graph Signal Hilbert Spaces
Benjamin Girault, Antonio Ortega, Shrikanth S. Narayayan
Graph vertex sampling set selection aims at selecting a set of ver-tices of a graph such that the space of graph signals that can be reconstructed exactly from those samples alone…
Generating Labels for Regression of Subjective Constructs using Triplet Embeddings
Karel Mundnich, Brandon M. Booth, Benjamin Girault +1
Human annotations serve an important role in computational models where the target constructs under study are hidden, such as dimensions of affect. This is especially relevant in m…
What's in a frequency: new tools for graph Fourier Transform visualization
Benjamin Girault, Antonio Ortega
Recent progress in graph signal processing (GSP) has addressed a number of problems, including sampling and filtering. Proposed methods have focused on generic graphs and defined s…
