Reliability-Aware Refinement of High-Resolution Human Mobility Origin-Destination Tables under Sparsity and Suppression
Yohei Shida, Ryosuke Susuta, Takuhiro Moriyama +1
High-resolution origin-destination (OD) tables derived from digital mobility traces can preserve fine-scale collective movement structure, but sampling, population expansion, and p…
On large bandwidth matrix values kernel smoothed estimators for multi-index models
Taku Moriyama
The kernel smoothing with large bandwidth values causes oversmoothing or underfitting in general. However, when irrelevant variables are included, the corresponding large bandwidth…
Privacy-Preserving Synthetic Dataset of Individual Daily Trajectories for City-Scale Mobility Analytics
Jun'ichi Ozaki, Ryosuke Susuta, Takuhiro Moriyama +1
Urban mobility data are indispensable for urban planning, transportation demand forecasting, pandemic modeling, and many other applications; however, individual mobile phone-derive…
On tail inference in iid settings with nonnegative extreme value index
Taku Moriyama
In extreme value inference it is a fundamental problem how the target value is required to be extreme by the extreme value theory. In iid settings this study both theoretically and…
