VerifiedThe core process of training a model is to iteratively update parameters in the direction of the loss function's gradient via gradient descent.79% similarUnverifiedThe contrastive pretraining loss and the semantic maintenance loss act together to achieve controlled co-evolution.77% similarVerifiedDuring the post-training phase, an excessively low loss may correspond to overfitting, where the model memorizes the training data and loses generalization ability.76% similarUnverifiedThe research team designed a progressive training recipe that introduces a normalized pixel loss, a Sobel edge loss, and a perceptual loss in sequence.75% similarUnverifiedPost-training refers to the stages a model goes through after pre-training, such as instruction fine-tuning, RLHF, or Constitutional AI, and post-training by different vendors shapes different failure modes.75% similar
