摘要：In biological measuring instruments design, it is time-consuming and expensive to acquire sufficient samples for calibration process. Transfer learning has provided an efficient approach for this problem by leveraging the labeled samples from calibration channels, considered as source domain, to annotate the target domain which has few labels under actual working conditions. In this paper, we design a general transfer regression framework improved by data-augmented ensemble learning called DA-TRTs. First, we modify two-stage TrAdaBoost.R2 to TrAdaBoost. RT (TRT) which concentrates more on hard examples during transfer boosting. Second, model stacking framework is introduced to improve the performance of regression, calling TRT as a base learner. Then, we introduce a simple data augmentation routine, based on label smoothing assumption. Data augmentation improves the strength in diversity of base learners and implicitly controls model complexity. Finally, to illustrate the performance of DA-TRTs, we conduct experiments on synthetic datasets.
