CPC trains human-motion predictors progressively on successive future segments and learns a Prior Compensation Factor (PCF) to adjust for loss of earlier information; CPC++ adds a fine-grained factor for separate prediction subtasks. On benchmark datasets and tested backbones, the methods generally improve or tie PGBIG, including 110.3 to 108.8 MPJPE at 1000 ms on Human3.6M, not evidence of universal transfer.
