At first I was using the up5.6 version of the PHP command installation composerLater when using composer, the command line was found to prompt PHP version too lowSo I downloaded the wamp and reinstalled the composer with version 7.1 PHP because the PHP-ML requirement must be version 7.1There are some problems with the installation, that is, the installation is unsuccessful, and there is no folder that appearsWhen installing with composer, use the path

MPP is the first time Microsoft has offered a training course on AI, the learning system for MPP, and I'll write a brief introduction later.???? MPP contains a lot of content, start learning time is very fast, to the back more and more difficult. This is one of the reasons why you haven't had the energy to update content for a long time.

By solving eigenvalues and eigenvectors, and selecting some characteristic vectors with large eigenvalues, the effect of dimensionality reduction is achieved.This paper continues the topic of PCA, which contains an application of PCA--lsi (latent Semantic indexing, implied semantic index) and an

It solves feature values and feature vectors and selects feature vectors with larger feature values to achieve dimensionality reduction.This article continues with the topic of PCA, including one application of PCA-LSI (Latent Semantic Indexing, implicit semantic index) and one implementation of PCA-SVD (Singular Value Decompos

It is believed that every webmaster knows that spiders crawl through the HTML code of the website and crawl the content of the website, and then give further feedback to the search engine to get the score, in order to give the ranking. Then in these processes we need to clearly describe the core theme of our site, but also is usually said title titles. Then we can use some HTML tags to further attract spiders, so that the key words better by spiders to understand the search engine to get a good

Generally, classification (or regression) is divided into two types: Parameter Learning and instance-based learning. The form of parameter learning is to learn the parameters of the corresponding model through a pile of training data, and then the training data is useless. For new data, the learned parameters can be used to draw a conclusion; Instance-based learning (also called memory-Based Learning) also uses training data such as KNN algorithm during prediction. Instance-based learning gene

Everything is difficult at the beginning, as the first blog, learn not to be easy to understand, fun, but to honestly make things clear.The thing that originated from the Kaggle competition was generously opening the source on GitHub, and Kaggle was very thoughtful to sort out these excellent solutions and implementations. For small white-level data workers, such as me, is a perfect opportunity to copy ideas and learn code. In order to enjoy this feast, I built a python environment under Windows
