We bring rigor to the vibrant activity of detecting power laws in empirical degree distributions in real-world networks. We first provide a rigorous definition of power-law distributions …
Clustering is a popular and useful unsupervised learning method with various algorithms for applying to many engineering problems. However, some practical and technical issues such …

The main objective of extreme value theory is essentially the estimation of quantities related to extreme events. One of its main issues has been the estimation of the extreme value index …
We use tail expectiles to estimate alternative measures to the value at risk and marginal expected shortfall, which are two instruments of risk protection of utmost importance in …
Continuous dynamic monitoring brings an important opportunity to evaluate the health and integrity of civil structures in a long-term manner. However, high dimensionality and sparsity …
