Sparse Principal Component Analysis via Wavelets for Distributed Data
Giovanni Barbosa Herrero, Rodney Vasconcelos Fonseca, Aluísio Pinheiro
The large volume of data and concerns about data privacy have motivated the development of techniques for distributed data, a problem also known as federated learning. In this scen…
Distributed Sparse Linear Regression under Communication Constraints
Rodney Fonseca, Boaz Nadler
In multiple domains, statistical tasks are performed in distributed settings, with data split among several end machines that are connected to a fusion center. In various applicati…
Wavelet Spatio-Temporal Change Detection on multi-temporal PolSAR images
Rodney Fonseca, Aluísio Pinheiro, Abdourrahmane Atto
We introduce WECS (Wavelet Energies Correlation Sreening), an unsupervised sparse procedure to detect spatio-temporal change points on multi-temporal SAR (POLSAR) images or even on…
Nonparametric methods for detecting change in Multitemporal SAR/PolSAR Satellite Data
Rodney Fonseca, Guilherme Ludwig, Michel Montoril +1
We employ nonparametric statistical procedures to analyse multitemporal SAR/PolSAR satellite images. The aim is two-fold. We seek parsimony in data representation as well as effici…
Wavelet estimation of the dimensionality of curve time series
Rodney V. Fonseca, Aluísio Pinheiro
Functional data analysis is ubiquitous in most areas of sciences and engineering. Several paradigms are proposed to deal with the dimensionality problem which is inherent to this t…
Inference in a bimodal Birnbaum-Saunders model
Rodney Fonseca, Francisco Cribari-Neto
We address the issue of performing inference on the parameters that index a bimodal extension of the Birnbaum-Saunders distribution (BS). We show that maximum likelihood point esti…
