In multi-class setting, target vector t is one-hot encoded vector with only one positive class (i.e. t i = 1 t_i = 1 t i = 1) and rest are negative class (i.e. t i = 0 t_i = 0 t i = 0).Due to this, we can notice … Web2.2. 3D context entropy model As a part of hyperprior model, context entropy model was first proposed in [12] and [10]. This context model is autoregressive over latents and is usually implemented in the format of 5×5mask convolution [12]. Such context entropy model plays an important role for the estimation of
