tPARAFAC2: Tracking evolving patterns in (incomplete) temporal data

Autor: Chatzis, Christos, Schenker, Carla, Pfeffer, Max, Acar, Evrim

Tensor factorizations have been widely used for the task of uncovering patterns in various domains. Often, the input is time-evolving, shifting the goal to tracking the evolution of underlying patterns instead. To adapt to this more complex setting,

A Time-aware tensor decomposition for tracking evolving patterns

Autor: Chatzis, Christos, Pfeffer, Max, Lind, Pedro, Acar, Evrim

Time-evolving data sets can often be arranged as a higher-order tensor with one of the modes being the time mode. While tensor factorizations have been successfully used to capture the underlying patterns in such higher-order data sets, the temporal

Autor: Linos Athena, Chatzis Christos, Alexopoulos Evangelos C

Publikováno v: BMC Public Health, Vol 6, Iss 1, p 50 (2006)

Abstract Background Personal exposure to pollutants is influenced by various outdoor and indoor sources. The aim of this study was to evaluate the exposure of Athens citizens to toluene and xylene, excluding exposure from active smoking. Methods Pass
