Several important applications, such as streaming PCA and semidefinite programming, involve a large-scale positive-semidefinite (psd) matrix that is presented as a sequence of linear updates. Because of storage limitations, it may only be possible to retain a sketch of the psd matrix. This paper...

This caused inefficiency in computations because the eigenvector and eigenvalue computation in PCA must be performed to each training sample in the chunk. The method was not suitable to handle incoming data chunk such as banking transaction, intrusion detection, and emerging data on the internet. ...
Our analytical and simulation results show that: 1) Though the NBA design can be implemented with low complexity, it cannot efficiently use user's bandwidth in general cases; 2) the PCA design can achieve the same bandwidth utilization efficiency as the ACA design in general cases; and 3) ...
Our analysis requires seeding the algorithm with a good initial estimate of the true cluster centers for which we provide an online PCA based clustering algorithm. Indeed, the asymptotic per-step time complexity of our algorithm is the optimal d·k while space complexity of our algorithm is O(...
The growth in publically available microbiome data in recent years has yielded an invaluable resource for genomic research, allowing for the design of new studies, augmentation of novel datasets and reanalysis of published works. This vast amount of micr
