Principal component analysis (PCA) is a widely used statistical technique for unsupervised dimension reduction. K-means clustering is a commonly used data clustering for performing unsupervised learning tasks. Here we

In web search, surfers are often faced with the problem of selecting their most wanted information from the potential huge amount of search results. The clustering of web search results is the possible solution, but the traditional content based clustering is not sufficient since it ignores many unique features of web pages. The link structure, authority, quality, or trustfulness of search results can play even the higher role than the actual contents of the web pages in clustering. These possible extents are reflected by Google's PageRank algorithm, HITS algorithm and etc. The main goal of this project is to integrate the authoritative information such as PageRank, link structure (e.g. in-links and out-links) into the K-Means clustering of web search results. The PageRank, inlinks and out-links can be used to extend the vector representation of web pages, and the PageRank can also be considered in the initial centroids selection, or the web page with higher PageRank influences the centroid computation to a higher degree. The relevance of this modified K-Means clustering algorithm needs to be compared to the ones obtained by the content based K-Means clustering, and the effects of different authoritative information also needs to be analyzed.

The existence, uniqueness, stability and regularity properties of traveling wave solutions of a bistable nonlinear integrodifferential equation are established, as well as their global asymptotic stability in the case of zero velocity continuous waves. This equation is a direct analog of the more familiar bistable nonlinear diffusion equation, and shares many of its properties. It governs gradient flows for free energy functionals with general nonlocal interaction integrals penalizing spatial nonuniformity.

Abstract—This paper examines a class of real-time control sys-tems in which each control task triggers its next release based on the value of the last sampled state. Prior work [1] used simula-tions to demonstrate that self-triggered control systems can be re-markably robust to task delay. This paper derives bounds on a task’s sampling period and deadline to quantify how robust the control system’s performance will be to variations in these param-eters. In particular we establish inequality constraints on a con-trol task’s period and deadline whose satisfaction ensures that the closed-loop system’s induced gain lies below a specified per-formance threshold. The results apply to linear time-invariant sys-tems driven by external disturbances whose magnitude is bounded by a linear function of the system state’s norm. The plant is regu-lated by a full-information controller. These results can serve as the basis for the design of soft real-time systems that guarantee closed-loop control system performance at levels traditionally seen in hard real-time systems.
