A Big Data-as-a-Service Framework: State-of-the-Art and Perspectives
TLDR
A tensor-based multiple clustering on bicycle renting and returning data is illustrated, which can provide several suggestions for rebalancing of the bicycle-sharing system and some challenges about the proposed framework are discussed.Abstract:
Due to the rapid advances of information technologies, Big Data, recognized with 4Vs characteristics (volume, variety, veracity, and velocity), bring significant benefits as well as many challenges A major benefit of Big Data is to provide timely information and proactive services for humans The primary purpose of this paper is to review the current state-of-the-art of Big Data from the aspects of organization and representation, cleaning and reduction, integration and processing, security and privacy, analytics and applications, then present a novel framework to provide high-quality so called Big Data-as-a-Service The framework consists of three planes, namely sensing plane, cloud plane and application plane, to systemically address all challenges of the above aspects Also, to clearly demonstrate the working process of the proposed framework, a tensor-based multiple clustering on bicycle renting and returning data is illustrated, which can provide several suggestions for rebalancing of the bicycle-sharing system Finally, some challenges about the proposed framework are discussedread more

Electrocorticogram classification based on wavelet variance and Fisher linear discriminant analysis
TL;DR: For a typical electrocorticogram(ECoG)-based brain-computer interface(BCI) system, a pattern recognition algorithm using wavelet analysis and Fisher linear discriminant analysis(FLDA) was proposed and showed that the max accuracy for test data was 92%, wavelet variance and wavelet packet variance could be taken as efficient features for ECoG.

Spectral Sparse Representation for Clustering: Evolved from PCA, K-means, Laplacian Eigenmap, and Ratio Cut.
TL;DR: It is found that the spectral graph theory underlies a series of elementary methods and can unify them into a complete framework, called spectral sparse representation (SSR), and Scut, a clustering approach derived from SSR reaches the state-of-the-art performance in the spectral clustering family.
