These are only for historical reasons and there is usually no reason to use import scipy in your code.Note: The import scipy as SP after sp. submodule fails, so the from import method above is recommended.Describes several functions:Because the SCIPY package is too complete and complex, and temporarily it seems that my needs are not particularly urgent, so simple introduction of a few I feel quite interesting function part, later in the Sklearn

Preface:
This article describes Ng's notes about machine learning about SVM. I have also learned some SVM theories and used libsvm before. However, this time I have learned a lot about Ng's content, and I can vaguely see the process from Logistic model to SVM model.
Basic Content:
When using the linear model for classification, You can regard the parameter vector as a variable. If the cost function

Introduction to mxnet Deep Learning LibraryAbstract: Mxnet is a deep learning library that supports languages such as C + +, Python, R, Scala, Julia, Matlab, and JavaScript; Support command and symbol programming; Can run on CPU,GPU, clusters, servers, desktops or mobile devices. Mxnet is the cxxnet of the next generation, Cxxnet learn from the idea of Caffe, but
Resources:1.-fpicGenerate position-independent Code (PIC) suitable for use with a shared library, if supported for the target machine. Such code accesses all constant addresses through a global offset table (GOT). The dynamic loader resolves the GOT entries when the program starts (the dynamic loader are not part of GCC; it's part of The operating system). If the GOT size for the linked executable exceeds a

If the data set as a training set and as the test set accuracy rate of about 75%, by modifying the number of iterations the final accuracy rate will converge to 84%.Iii.

Brief introduction
In recent years, because of the cloud platform, large data, high-performance computing, machine learning and other areas of progress, artificial intelligence also fire up. Face recognition, speech recognition and other related functions have been proposed, but can form products and large-scale use of small. Because it is difficult for non-professional professionals to achieve a complete s
. Naive Bayesian classifier has two kinds of polynomial model and Bernoulli model when it is used in text classification, and the algorithm realizes these two models and is used for spam detection respectively, which has remarkable performance.Note: Personally, the "machine learning Combat" naive Bayesian chapter on the text classification algorithm is wrong, whether it is its Bernoulli model ("word set") o

I like to work based on web apps. It is very attractive to implement an application that can be run from anywhere and on any device. Over the past few months, I've been trying to get some basic lightweight machine learning algorithms that run on JavaScript and then use them to build " smart " Web apps. With the advent of node, it is possible to train the model on the server side and then use these models to
