Introduction ChangeLog V0: Based on MAE + Transformer 2d kps feature (x, y) position embedding spatial-temporal mask V1 3d kps feature (x, y, conf) filter low conf segment add low-conf mask V2 add multi loss reconstruction_loss full_sequence_reconstruction_loss velocity_consistency_loss acceleration_consistency_loss total_variation_loss V3 add body bone subset info bone render while inference add body_bone_length_loss V4: add tokenizer (Vanilla STTF-like) keypoint tokenizer, instead of flattern one spatial-temporal embedding, instead of position embedding V5: add asymmetric encoder-decoder (large-small) MAE-like asymmetric encoder-decoder a fixed total ratio of spatial-temporal mask Problem: Scale-up failure add lr scheduler Future Plan Bert-based: double direction context input TAE-based: stream chatsign generation Video Part: SVD / GAN ?
