Machine Learning Tools for Radio Map Estimation in Fading-Impaired Channels
Teganya, Yves (Doctoral Dissertations at the University of Agder; no. 297, Doctoral thesis, 2020)In spectrum cartography, also known as radio map estimation, one constructs maps that provide the value of a given channel metric such as as the received power, power spectral density (PSD), electromagnetic absorption, or ... -
Online Machine Learning for Graph Topology Identification from Multiple Time Series
Zaman, Bakht (Doctoral Dissertations at the University of Agder; no. 298, Doctoral thesis, 2020)High dimensional time series data are observed in many complex systems. In networked data, some of the time series are influenced by other time series. Identifying these relations encoded in a graph structure or topology ... -
