Environment and usage

The following environments are required:

• Python 3.7 (anaconda is preferable)
• k3d (for visualize tensor case, not necessarily required)

Code

To install it,

pip install SKPD

Matrix example shows

An illustration of estimated coefficients $ \hat{C} \in\mathbb{R}^{128\times 128}$ in the linear model simulation with $n=1000$ and noise level $\sigma = 1$. From left to right columns: True signals; our 1-term SKPD; 3-term SKPD.
