Given a temporal dense tensor and an arbitrary time range,
how can we efficiently obtain latent factors in the range?
Tucker decomposition is a fundamental tool
for analyzing dense tensors
to discover hidden factors,
and has been exploited
in many data mining applications.
However,
existing decomposition methods
do not provide the functionality
to analyze a specific range of a temporal tensor.

In this paper, we propose Zoom-Tucker,
a fast and memory-efficient Tucker decomposition method
for finding hidden factors of temporal tensor data in an arbitrary time range.
The existing methods are one-off,
with the main focus on performing
Tucker decomposition once
for a whole input tensor.

Although a few existing methods
with a preprocessing phase
can deal with a time range query,
they are still time-consuming
and suffer from low accuracy.
