The β_t schedule is the key hyperparameter controlling the pace of noise addition in the forward process; β_t is a pre-set sequence of small positive numbers that does not participate in training, typically growing from β_1≈1e-4 to β_T≈0.02 linearly or by cosine.

UnverifiedDiffusion model training objectives typically involve predicting noise ε or velocity field v, and the noisy input can be expressed as x_t = α_t·x_0 + σ_t·ε.65% similarUnverifiedThis recursive process has a unique stationary causal solution and satisfies a geometric forgetting initialization condition, with the convergence rate controlled by the learning rate γ.64% similarUnverifiedThe classifier uses both TF-IDF word features and sentence vectors generated by all-MiniLM-L6-v2, concatenating the two before training a balanced logistic regression classifier.61% similarUnverifiedSFT cold start refers to first using supervised fine-tuning to give the model basic target behavior patterns before reinforcement learning, in order to avoid the extremely sparse reward signal problem when RL explores from scratch.58% similarUnverifiedTime per output token (TPOT) measures the speed at which a model generates tokens one by one during the autoregressive decoding phase.58% similar
