After the publication of our article , we found that a few errors were introduced during the production process.
The mathematical definition of expanded temporal block given in Definition 3 (Expanded temporal block) should have been "the corresponding expanded temporal block satisfies: " rather than "the corresponding expanded temporal block satisfies: ".
And the subscript of some variable involved in partial correlation calculation (formula (2)) given in Definition 4 (Partial correlation) should have been "X, Z" rather than "X, 2". The corrected formula is shown here:
We regret any inconvenience these errors may have caused.
