WebThe init function of this optimizer initializes an internal state S_0 := (m_0, v_0) = (0, 0) S 0 := (m0,v0) = (0,0), representing initial estimates for the first and second moments. In practice these values are stored as pytrees containing all zeros, with the same shape as … WebMay 11, 2024 · 2. We design an estimator to estimate the multiple training status. The sample hardness is defined with a more accurate and comprehensive description. To the best of our knowledge, it is the first attempt to introduce multiple information about training status and feature positions into Softmax loss.
WebJan 7, 2024 · Sampled softmax loss emerges as an efficient substitute for softmax loss. Its special case, InfoNCE loss, has been widely used in self-supervised learning and exhibited remarkable performance for contrastive learning. Nonetheless, limited studies use sampled softmax loss as the learning objective to train the recommender.
