Ten cent Weibo is one of the largest micro-blogging websites in China. There are more than 200 million registered users on Ten cent Weibo, generating over 40 million messages each day. Recommending appealing items to users is a mechanism to reduce the risk of information overload. The task of this paper is to predict whether or not a user will follow an item that has been recommended to the user by...
Small sample size (SSS) problem is still a puzzle in classification. For the generally used Maximum Likelihood Classifier (MLC), the small size of training sample with respect to the high-dimensional data deteriorates the performance of parameter estimation. In the extreme case, MLC could be disabled by the singularity of the covariance matrices. Generally speaking, predecessors experimented in two...
In this paper, we present a design methodology for automatic platform generation of future heterogeneous systems where communication happens via the network-on-chip (NoC) approach. As a novel contribution, we consider explicitly the information about the user experience into a design flow which aims at minimizing the workload variance; this allows the system to better adapt to different types of user...
The metamodeling approach has been an important method to reduce the computational expense of complex system simulation. Metamodeling is the process of building a ldquomodel of a modelrdquo to provide a fast surrogate model for computational expensive simulation code. Main metamodeling techniques include polynomial regression, kriging, radial basis function and support vector regression. In this paper...
