The 2014 guaranteed algorithm for the robust PCA problem (with the input matrix being = +) is an alternating minimization type algorithm. [12] The computational complexity is () where the input is the superposition of a low-rank (of rank ) and a sparse matrix of dimension and is the desired accuracy of the recovered solution, i.e., ‖ ^ ‖ where is the true low-rank component and ^ is the ...
It was later shown that some types of NMF are an instance of a more general probabilistic model called "multinomial PCA". [44] When NMF is obtained by minimizing the Kullback–Leibler divergence, it is in fact equivalent to another instance of multinomial PCA, probabilistic latent semantic analysis, [45] trained by maximum likelihood estimation.
Communications of the ACM is the monthly journal of the Association for Computing Machinery (ACM). It was established in 1958, [2] with Saul Rosen as its first managing editor. It is sent to all ACM members. [3] [4] Articles are intended for readers with backgrounds in all areas of computer science and information systems. The focus is on the ...
In public key infrastructure (PKI) systems, a certificate signing request (CSR or certification request) is a message sent from an applicant to a certificate authority of the public key infrastructure (PKI) in order to apply for a digital identity certificate. The CSR usually contains the public key for which the certificate should be issued ...
In statistics, principal component regression (PCR) is a regression analysis technique that is based on principal component analysis (PCA). PCR is a form of reduced rank regression. [1] More specifically, PCR is used for estimating the unknown regression coefficients in a standard linear regression model.
Jennifer Lopez is shining bright!. On Thursday, Dec. 5, the actress and singer, 55, was honored with the Maverick Award at the 2024 IndieWire Awards at Citizen News in Los Angeles.
It focuses on analysis and construction of algorithms and programs, and the interaction of programs and architecture. Algorithms documented in TOMS are available as the Collected Algorithms of the ACM at calgo.acm.org. The purpose of the journal was laid out by its founding editor, John Rice, in the inaugural issue.

Early AWS "building blocks" logo along a sigmoid curve depicting recession followed by growth. [citation needed]The genesis of AWS came in the early 2000s. After building Merchant.com, Amazon's e-commerce-as-a-service platform that offers third-party retailers a way to build their own web-stores, Amazon pursued service-oriented architecture as a means to scale its engineering operations, [15 ...
