Contrastive Spatio-Temporal Pretext Learning for Self-Supervised Video Representation

AAAI 2022technical

Spatio-temporal representation learning is critical for video self-supervised representation. Recent approaches mainly use contrastive learning and pretext tasks. However, these approaches learn representation by discriminating sampled instances via feature similarity in the latent space while ignor…
