This paper compares models trained with classification algorithm with those trained using regression algorithm. We use technical indicators, 43 bond characteristics and 94 stock characteristics as predictors. We find very strong evidences of the superior predictive ability of classification...

To realize the evaluation and hierarchical management of the meta-competency of the bid evaluation experts, this paper constructs the evaluation index system of bid evaluation expert meta-competence by referring to relevant literature and consulting expert opinions. By judging the importance of...

The importance of software based on machine learning is growing rapidly, but the potential of prototypes may not be realized in operation. This study identified six categories of challenges for verification and validation of machine learning applications during production. Subsequently,...
