Abstract

We define a Hidden Markov Model (HMM) in which each hidden state has time-dependent activity levels\textit{activity levels} that drive transitions and emissions, and show how to estimate its parameters. Our construction is motivated by the problem of inferring human mobility on sub-daily time scales from, for example, mobile phone records.
