PHP-ML is a machine learning library written using PHP. While we know that Python or C + + provides more machine learning libraries, in fact, most of them are slightly more complex and configured to be desperate for many novices. PHP-ML This machine learning library is not particularly tall on the algorithm, but it has the most basic machine learning, classification and other algorithms, our small companies

In the spark2.0 version, there are two implementation libraries for machine learning algorithms mllib and ML, such as random forests:Org.apache.spark.mllib.tree.RandomForestAndOrg.apache.spark.ml.classification.RandomForestClassificationModel The two libraries correspond to different usage methods, Mllib is the rdd-based API,ML is a data structure based on the ML

Unknowingly disappeared for a long time, the public number has not been updated. Because ran to learn the Microsoft AI direction of the MPP course. 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.

Stanford ml Public Lesson Note 15In our last note we talked about PCA (principal component analysis).PCA is a kind of direct dimensionality reduction method. 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 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

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

equivalent to "Least Squares. 7.3.1 Maximum Likelihood Estimation derivation In the following derivation, note that the "format" of x and W is very simple. Note that when processing "vectors", the standards are column vectors. If a book appears in the form of a single vector, you can only say: Throw it. Detailed derivation: 7.3.2 ry After finding W, the ry of y_hat = w'x is that y_hat is the projection point of Y in the Space Formed by X columns ". 7.3.3 convex Convexity Only when the funct

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
