DOI: 10.1016/j.ssci.2017.11.019

Abstract: Abstract This paper proposes a model to assess train passing a red signal without authorization, a SPAD. The approach is based on Big Data techniques so that many types of data may be integrated, or… read more here.

DOI: 10.1038/s41598-025-90152-7

Abstract: The theory of Group Equivariant Non-Expansive Operators (GENEOs) was initially developed in Topological Data Analysis for the geometric approximation of data observers, including their invariances and symmetries. This paper departs from that line of research… read more here.

DOI: 10.1109/tsipn.2025.3540701

Abstract: Graph learning is an important problem in the field of graph signal processing. However, the data available in real-world applications are often contaminated with outliers, which makes the application of traditional methods challenging. In this… read more here.

DOI: 10.1109/tsp.2024.3361712

Abstract: Blind source separation (BSS) is a signal processing subject that has recently been extended to graph signals. Graph signals that are smooth on their own graphs provide an opportunity to separate them from their summation… read more here.
