Over recent decades, machine learning, an integral subfield of artificial intelligence, has revolutionized diverse sectors, enabling data-driven decisions with minimal human intervention. In particular, the field of educational assessment emerges as a promising area for machine learning applications, where students can be classified and diagnosed using their performance data. The objectives of Diagnostic Classification Models (DCMs), which provide a suite of methods for diagnosing students’ cognitive states in relation to the mastery of necessary cognitive attributes for solving problems in a test, can be effectively addressed through machine learning techniques. However, the challenge lies in the latent nature of cognitive status, which makes it difficult to obtain labels for the training dataset. Consequently, the application of machine learning methods to DCMs often assumes smaller training sets with labels derived either from theoretical considerations or human experts. In this study, the authors propose a supervised diagnostic classification model with data augmentation (SDCM-DA). This method is designed to utilize the augmented data using a data generation model constructed by leveraging the probability of correct responses for each attribute mastery pattern derived from the expert-labeled dataset. To explore the benefits of data augmentation, a simulation study is carried out, contrasting it with classification methods that rely solely on the expert-labeled dataset for training. The findings reveal that utilizing data augmentation with the estimated probabilities of correct responses substantially enhances classification accuracy. This holds true even when the augmentation originates from a small labeled sample with occasional labeling errors, and when the tests contain lower-quality items that may inaccurately measure students’ true cognitive status. Moreover, the study demonstrates that leveraging augmented data for learning can enable the successful classification of students, thereby eliminating the necessity for specifying an underlying response model.

High-performance bifunctional electrocatalysts that simultaneously and efficiently catalyze oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) have become the bottleneck and main challenge for rechargeable zinc–air batteries. The components need to be comprehensively designed to enhance the formation possibility for the respective activities of ORR and OER. Nevertheless, the elements and types of chemical bonds generate an almost infinite space of potential candidates. In this work, we proposed a rational design strategy for efficient bifunctional oxygen electrocatalysts by a data-driven method. According to the inferred ΔE from E10 and E1/2 machine learning models among all the bond combinations, a bond combination of C–N, C–C, Fe–N, Ru–O, and C–P was considered with superior possibility to have bifunctional activity owing to its highest occurrence frequency. The experimental results further confirmed that this component and bonding method indeed have ORR/OER bifunctional activity, which has not been reported yet. This strategy brings novel and efficient insights for bifunctional electrocatalyst design from a huge potential exploration space.
