UnverifiedThe researchers proposed a credal-set-based method in which the learner's prediction output is no longer a single probability distribution but a set of possible distributions presented in the form of a credal set.76% similarUnverifiedThe residual distribution is defined as follows: for tokens where the target model probability p(x) is greater than the draft model probability q(x), the residual probability is proportional to max(0, p(x)-q(x)); this mechanism ensures that the marginal distribution of the sampled results strictly equals the original distribution of the target model.66% similarUnverifiedUnder the Bayesian framework, when prior information is insufficient, the set of posterior distributions induced by all reasonable priors constitutes a credal set.66% similarUnverifiedTraditional robust optimization methods often assume that the distribution shift lies within some known uncertainty set, whereas Credal set methods do not rely on strong assumptions about the form of the shift and directly model the model's epistemic uncertainty.64% similarUnverifiedBayesian updating is a probabilistic reasoning method that dynamically adjusts beliefs based on new evidence, and its core formula is: posterior probability = (likelihood × prior probability) / evidence probability.63% similar
