%description
Tensor Gaussian graphical models (GGMs) have important applications in
numerous areas, which can interpret conditional independence structures
within tensor data. Yet, the available tensor data in one single study is
often limited due to high acquisition costs. Although relevant studies can
provide additional data, it remains an open question how to pool such
heterogeneous data. This package implements a transfer learning framework
for tensor GGMs, which takes full advantage of informative auxiliary
domains even when non-informative auxiliary domains are present,
benefiting from the carefully designed data-adaptive weights. Reference:

graphical models" <arXiv:2211.09391>.
