norm of complex number

Reprinted article: Norm Rule in machine learning (i) L0, L1 and L2 norm[Email protected]Http://blog.csdn.net/zouxy09Today we talk about the very frequent problems in machine learning: overfitting and regulation. Let's begin by simply understanding

I. Introduction of supervised learningThe supervised machine learning problem is nothing more than "Minimizeyour error while regularizing your parameters", which is to minimize errors while the parameters are being parameterized. The minimization

The transmission gate of the original text: a brief talk on L0,l1,l2 norm and its application Talking about L0,L1,L2 norm and its application In mathematical branches such as linear algebra, function analysis, a norm (Norm) is a function that gives

  L2 norm In addition to the l1 norm, there is also a more favored normalization norm that is L2 norm: | w | 2. It is not inferior to the l1 norm. It has two good terms. In regression, someone calls it ridge regression ), someone calls it "Weight

Norm rule in machine learning (II.) kernel norm and rule item parameter selection[Email protected]Http://blog.csdn.net/zouxy09In the previous blog post, we talked about the l0,l1 and L2 norm, which we ramble about in terms of nuclear norm and rule

1. Vector Norm Norm, Norm, is a concept similar to "Length" in mathematics, which is actually a kind of function.The regularization (regularization) and sparse coding (Sparse coding) in machine learning are very interesting applications.For Vector

After the 90 's, with the establishment of the WFMC Alliance, the BPM market crowded in full swing, the workflow technology has been developed rapidly, including IBM, Oracle and other large software vendors in the field of work flow of the banner of

first, over-fitting The supervised machine learning problem is nothing more than "Minimizeyour error while regularizing your parameters", which is to minimize errors while the parameters are being parameterized. The minimization error is to let our

As a preprocessing method, image processing is almost a prelude to all image processing methods. In many cases, image filtering as a preprocessing method of image recognition, it needs to satisfy two restrictive conditions: the contrast is
