Loss Function: A self-supervised loss function is used to maximize the agreement between the pair of latent representations obtained as outputs from the projec-tion head. In our work we have proposed a negative-sample free hybrid loss function named VICRegHSIC loss, combining the VICReg loss [Bardes et al., 2024]
In supervised learning, there are two main types of loss functions — these correlate to the 2 major types of neural networks: regression and classification loss functions 1. Regression Loss Functions — used in regression neural networks; given an input value, the model predicts a corresponding output value (rather … See more First, a quick review of the fundamentals of neural networks and how they work.
