The rapid development of Internet technology has ushered in the era of information overload. How to pick out information with excellent quality and reduce unnecessary browsing time is a problem to be solved urgently. In order to recommend information that users might be interested in, this paper presents a new personalized recommendation algorithm with the quality of service (QoS) constraints based...
The performance of an ANC system largely depends on the availability of an accurate secondary path model. This is however a major challenge in multichannel ANC where the computational complexity increases significantly with the number of secondary sources and error sensors. This paper proposes wave-domain adaptive processing algorithm for multichannel ANC with online secondary modelling to cancel...
In this paper, we consider the problem of efficiently identifying the Pareto optimal designs out of a given set of alternatives, for the case where alternatives are evaluated on multiple stochastic criteria, and the performance of an alternative can only be estimated via sampling. We propose a simple myopic budget allocation algorithm based on the idea of small-sample procedures. Initial empirical...
Hybrid recommender systems combine different approaches to provide better recommendations. The most common hybrid algorithms mix collaborative, content-based, demographic filtering among others. However, these hybrid approaches seldom consider the user-recommender interaction. In this paper, we propose a new hybrid recommender system through considering the user-recommender interaction. First, we...
The medial axis (or a topological skeleton) is a thinner version of a geometric object The medial axis was first introduced by Blum as a description of shape. Its classical definitions include grass-fire model and maximal disk model The grass-fire model means that an object's boundary is taken as an initial fire front that propagates within the object's interior region. Points where the fire front...
Image segmentation is an important and classic problem in image processing and computer vision. Thresholding is applied to many fields, because of its less computation and stable performance. The key of thresholding method is to determine the adaptive threshold. In order to segment biological image effectively, a new adaptive thresholding method is proposed. First, two dimension minimum entropy is...
Recently, lattice reduction has been widely used for signal detection in multiinput multioutput (MIMO) communications. In this paper, we present three novel lattice reduction algorithms. First, using a unimodular transformation, a significant improvement on an existing Hermite-Korkine-Zolotareff-reduction algorithm is proposed. Then, we present two practical algorithms for constructing Minkowski-reduced...
In order to overcome the defect of physic-chemical monitoring system and enhance the intelligence of biological monitoring technology, an online monitoring system of fish behavior is proposed in this paper. The main contributions of this system are as follows: 1) adaptive background updating algorithm (ABU); 2) automatic camshift tracking algorithm (ACT) with twice searching; 3) particle filter tracking...
In order to save the consumption in terms of instruction and storage, to simplify the code, and to enhance the coding quality, this paper, based on the architecture design of the stereo encoder, has analyzed the arranging relationship between the channel and the block in each frame and has optimized the data process and the looping mode of the current encoder. In addition, the start points and the...
