First, use rownum for record ranking: In the previous "Introduction to Oracle Development analysis function over", we understand the basic application of analytic function, now we consider the following questions: ① to rank all customers by total order② rank by region and customer order totals③ find the top 13 customers in order total④ find customers with the highest and lowest order totals⑤ find the top

Data dimensionality Reduction--low rank recoveryIn the actual signal or image acquisition and processing, the higher the dimension of the data, the greater the limit to the data collection and processing. For example, it is often difficult to acquire signals in three-dimensional or four-dimension (three spatial dimensions plus one spectral dimension or one time dimension). However, with the increase of data dimensionality, there are often more correla

linearly with each other, then the two vector groups are called equivalent. Two Principles, formulas, and rules 1. The basic principle of determining the linear correlation of a vector group: When the upper form is set up, not all is 0, then can determine the linear correlation, if only, then can determine linearly independent. 2. The determination of the linear correlation of vectors 1) A vector A is a sufficient and necessary condition for linear correlation: a=0; 2 The sufficient and necess
