摘要:A new, non–parametric and binless estimator for the mutual information of a d–dimensional random vector is proposed. First of all, an equation that links the mutual information to the entropy of a suitable random vector with uniformly distributed components is deduced. When ...

摘要:Abstract(#br)Complex networks in different areas exhibit degree distributions with a heavy upper tail. A preferential attachment mechanism in a growth process produces a graph with this feature. We herein investigate a variant of the simple preferential attachment model, who...

摘要:Abstract(#br)For a martingale M starting at x with final variance σ 2 , and an interval ( a , b ) , let Δ = b − a σ be the normalized length of the interval and let δ = | x − a | σ be the normalized distance from the initial point to the lower endpoint of the interval. ...

摘要:Abstract(#br)Despite the progresses of statistical and machine learning techniques, simultaneous recordings from many neurons hide important information and the connections characterizing the network remain generally undiscovered. Discerning the presence of direct links between n...

摘要:Abstract(#br)Given a two-dimensional correlated diffusion process, we determine the joint density of the first passage times of the process to some constant boundaries. This quantity depends on the joint density of the first passage time of the first crossing component and o...

摘要:ABSTRACT(#br)During development of an electronic or mechanical system, multiple sources of data are often available. Combining such data helps tackle complex problems and tradeoff decisions. Individually, these data sources provide partial information on the problems we try to so...

摘要:Abstract(#br)We consider the multivariate point process determined by the crossing times of the components of a multivariate jump process through a multivariate boundary, assuming to reset each component to an initial value after its boundary crossing. We prove that this poi...

摘要:Abstract(#br)We give a common description of Simon, Barabási–Albert, II-PA and Price growth models, by introducing suitable random graph processes with preferential attachment mechanisms. Through the II-PA model, we prove the conditions for which the asymptotic degree distri...

摘要:Abstract(#br)With the aim of considering models related to random graphs growth exhibiting persistent memory, we propose a fractional nonlinear modification of the classical Yule model often studied in the context of macroevolution. Here the model is analyzed and interpreted in t...
