In this study, the authors propose a multi-group–multi-class domain adaptation framework to recognise events in consumer videos by leveraging a large number of web videos. The authors’ framework is extended from multi-class support vector machine by adding a novel data-dependent regulariser, which can force the event classifier to become consistent in consumer videos. To obtain web videos, they search...
The direct-fired system with duplex inlet and outlet ball pulverizer is more difficult to establish the precise mathematical model because of its multivariable strongly coupling and strongly nonlinear, and the impact factors of mill output are numerous. The gray relational analysis theory used to analyze the duplex inlet and outlet ball mill system, and obtained the gray correlation degree of every...
Accurate springback prediction and control is essential for sheet metal forming. In this paper, back propagation (BP) neural network and genetic algorithm (GA) was introduced to predict springback of complex sheet metal forming parts. GA was used to optimize the weights of BP neural network and the results were compared with those of traditional BP neural network and regression model. The comparison...
