A modelling method for mapping the relationships between resources and service performance based on I-ABC-ELM

Aiming at the problem of service performance modelling, this paper uses ANN to establish the mapping relationships between virtual machine resource status and cloud service performance, and proposes an I-ABC-ELM method to train ANN. For the stability problems of the ELM training, this paper proposes the use of I-ABC algorithm to optimize the input layer weight matrix and hidden layer bias in ELM. At the same time, a new method called I-ABC to solve the defect of the local optimal solution of the artificial bee colony algorithm is proposed. Experiments show that I-ABC-ELM greatly improves the prediction ability and stability.
