This contribution reports a crosscheck results of JVET-AI0066(EE2-2.7:Regularized EIP/CCCM). JVET‐AI0066 reports the results of EE2-2.7, which involves applying L2-regularization to least squares regression to solve EIP and CCCM model coefficients. In test 2.7a, regularized EIP is used. In test 2.7b, regularized CCCM is used. Test 2.7c is the combination of 2.7a and 2.7b. It reports that the software implementation is in that way and our experimental results match with those provided by the proponents and don’t observe significant difference in execution time.
