CentralNotice QR decomposition From Wikipedia, the free encyclopedia Jump to: navigation , search In linear algebra , a QR decomposition (also called a QR factorization ) of a matrix is a decomposition of a matrix A into a product A = QR of an orthogonal matrix Q and an upper triangular matrix R . QR decomposition is often used to solve the linear least squares problem, and is the basis for a particular eigenvalue algorithm , the QR algorithm . If A has n linearly independent columns, then the first n columns of Q form an orthonormal basis for the column space of A . More specifically, the first k columns of Q form an orthonormal basis for the span of the first k columns of A for any 1 ≤ k ≤ n . [ 1 ] The fact that any column k of A only depends on the first k columns of Q is responsible for the triangular form of R . [ 1 ] 1 History 2 Definitions 2.1 Squar...

corrects IE6 width calculation google_ad_section_start(name=default) Wednesday, November 19, 2014 We’ve been busy building our next-generation Netflix.com web application using Node.js. You can learn more about our approach from the presentation we delivered at NodeConf.eu a few months ago. Today, I want to share some recent learnings from performance tuning this new application stack. We were first clued in to a possible issue when we noticed that request latencies to our Node.js application would increase progressively with time. The app was also burning CPU more than expected, and closely correlated to the higher latency. While using rolling reboots as a temporary workaround, we raced to find the root cause using new pe...

CentralNotice Finger tree From Wikipedia, the free encyclopedia Jump to: navigation , search For the binary search tree, see finger search tree . A finger tree is a purely functional data structure used in efficiently implementing other functional data structures. A finger tree gives amortized constant time access to the "fingers" (leaves) of the tree, where data is stored, and also stores in each internal node the result of applying some associative operation to its descendants. This "summary" data stored in the internal nodes can be used to provide the functionality of data structures other than trees. For example, a priority queue can be implemented by labeling the internal nodes by the minimum priority of its children in the tree, or an indexed list/array can be implemented with a labeling of nodes by the count of the leaves in their children. Finger trees can pro...
