KLD measures relative entropy, i.e., the extra number of bits needed to encode the original model's output using the quantized model's distribution, so its unit is bits/token.

UnverifiedKLD (KL divergence) measures the difference between two probability distributions, with the formula D_KL(P||Q)=∑_x P(x)log(P(x)/Q(x)).71% similarUnverifiedKL divergence is used to compare the difference in output probability distributions between the fine-tuned model and the original model given the same input; a larger value indicates greater deviation, and a KLD of 0.0244 means the fine-tuning has hardly changed the model's overall behavioral distribution.70% similarUnverifiedEntropy and KL divergence in information theory are important foundations for understanding loss function design and generative models (such as VAEs and diffusion models)67% similarPartially VerifiedIn information theory, entropy H(p) measures the uncertainty of a probability distribution p, and is equivalent to the average number of bits required to optimally encode information drawn from that distribution.66% similarUnverifiedSFDA completes adaptation by relying on the model's internal knowledge, such as batch normalization statistics, entropy minimization, and pseudo-label self-supervision64% similar
