On the Inability of Markov Models to Capture Criticality in Human Mobility [PDF]

, 2018
We examine the non-Markovian nature of human mobility by exposing the inability of Markov models to capture criticality in human mobility. In particular, the assumed Markovian nature of mobility was used to establish a theoretical upper bound on the ...
