This paper presents a virtual laboratory platform based on the B/S structure framework in distributed network, and the virtual laboratory platform includes the software and hardware resources. The virtual laboratory allows network terminal to access through the network. The two parts of the virtual laboratory are laboratory device interface platform and(More)
Although differential evolution (DE) algorithms have shown great power in solving continuous optimization problems, it is still a challenging task to design an efficient binary variant of DE algorithm. In this paper, we propose a binary learning differential evolution (BLDE) algorithm, which can efficiently search the feasible region by learning from the(More)

A new method based on rough set theory to classify goods is put forward in this paper. Firstly, we set up a decision table of goods classification; secondly we get some certain rules from this decision table and get a new totally disharmonious decision table by deleting the objects, which can be identified by these certain rules; finally, we get the(More)
Facial expression has many applications in human-computer interaction. Although feature extraction and selection have been well studied, the specificity of each expression variation is not fully explored in state-of-the-art works. In this work, the problem of multiclass expression recognition is converted into triplet-wise expression recognition. For each(More)
