- Abstract:
-
Aiming at the problem that the number of label samples is small and the cost of manual labeling is high in the industrial production process, an active learning algorithm based on a two-tier optimization strategy is proposed. First, establish different prediction models to evaluate the amount of information contained in unlabeled samples; secondly, fully consider the distribution information of the samples and, from the three perspectives of sample uncertainty, difference, and representativeness, propose new evaluation indicators, preferably unlabeled samples, and remove redundant information; finally, the double-layered preferred samples are manually labeled, and the labeled sample set is reconstructed for modeling application. The application simulation of the algorithm through the industrial process data of the debutanizer verifies the effectiveness and performance of the proposed algorithm.
