With the exploration of the World Wide Web, more and more entities are involved in various online applications, e.g., recommender systems and social network services. In such context, high-dimensional sparse matrices describing the relationships among them are frequently encountered. It is highly important to develop efficient non-negative latent factor (NLF) models for these high-dimensional sparse...
Multicarrier Phase-Coded (MCPC) signals have been recently introduced to radar systems as a kind of wideband signal. In this paper we study the wideband ambiguity function (WAF) of multicarrier phase-coded signals. Based on the fact that scattering characteristics of target varies with frequency, we propose an approach which adaptively changes the transmitted frequency weights to improve radar's WAF...
A model of XML document is extended by considering both path and frequency information, namely the frequency-path model. Based on this model, a structural similarity calculation algorithm with position and frequency weight by longest common subsequence (PFWLCS) is proposed, which is fast and has high precision. Furthermore the selection of the position and frequency factors are discussed in depth...
This paper presents the design, analysis, and performance evaluation of a new class of globally asymptotically stable filters for attitude estimation. The design is based directly on the sensor measurements as opposed to traditional solutions that resort to parameterizations of the attitude, e.g., Euler angles, quaternions, or rotation matrices, and therefore it does not have problems such as singularities,...
