Efficient Method of Formal Event Analysis

Abstract

Abstract. Based on the philosophic idea about static concept, Professor R.Wille in Germany had provided the theory about formal concept analyses firstly in 1982, which opens out inwardness of static concept and relation between the concepts well. But the theory has evident limitation for representing dynamic event. The paper extends the theory to be a more generic model. On the basis of the definition of event proposed by us, more formalized description of event is given, a method to build formal event lattice from formal event context is suggested. Then the feasibility of the method is demonstrated from theory and instance. The model of Formal Event lattice repairs the limitation of formal concept lattice, so it can characterize the essence of the dynamic world very well. It will exert effect in the application in the fields of network resource management, Web servers, event ontology, robot control, marketing strategy, data mining and etc.

Prediction of electrical properties of GAAFET based on integrated learning model

“…(a), which consists of three sub-models: DL model, k nearest neighbor (KNN)[19] model, and random forest (RF)[20] model, and the integration of the models is achieved by the greedy ensemble algorithm[21]. The DL model is a convolutional neural network (CNN) model, which consists of an input layer, two fully connected input extension layers, two convolutional layers, two fully connected layers, and one output layer, as shown in figure3(b).…”
