Adaptive Learning of Polynomial Networks: Genetic Programming, Backpropagation and Bayesian Methods (Genetic and Evolutionary Computation)

This publication offers theoretical and functional wisdom for develop­ ment of algorithms that infer linear and nonlinear versions. It deals a strategy for inductive studying of polynomial neural community mod­els from information. The layout of such instruments contributes to higher statistical information modelling whilst addressing projects from quite a few components like approach id, chaotic time-series prediction, monetary forecasting and knowledge mining.

Web service QoS information model Firstly, when the Web service was once invoked, the Web service QoS information can be described by a two-dimensional user-service matrix. Service users may come from different locations and have little knowledge about each other, so it is quite normal they wouldnt share the QoS information with others. Consequently, as shown in Figure 1 (a), only a sub-fraction of the QoS information is available. To acquire sufficient information for Web service recommendation, the collaborative filtering methods[2,3,4,5,6] were adopted to predict the lacking QoS information.

Also, the QoS Value of Web services may change over time due to the dynamic environment. How to handle the dynamic data streams of incoming service QoS value is a big challenge. To address above problems, we propose an Web Service Recommendation Framework by considering the temporal information. We explore to envision such QoS value data as a tensor and transform it into tensor factorization problem. A Tucker decomposition (TD) method is proposed to cope with the model which includes multidimensional information: user, service and time.

For finer grid with much bigger data that may be needed in the future, gpuPOM has to be extended to a GPU cluster. It is a part of the future work. 140 CUDA-aware MPI D2H2D MPI overlapping Our design Seconds per simulation day 120 100 80 60 40 20 0 1-GPU 2-GPUs 4-GPUs Number of GPUs Fig. 5.
