ruby machine learning

Code blocks are more or less exposed in other languages, such as Perl sort{$a In the process of learning Ruby, the understanding of code blocks is a step further, not only simplifying the functionality of the code, but also involving scopes, callable objects and other knowledge.code blockCode blocks are defined in curly braces or do...end keywords, and when a block is passed to a method, it can be recalled

middle because alias is a keyword and not a method (where is the keyword in the structure, and what is the difference between the method)? ）。 When a new name is called, the original method is called when the alias is added. The method that is named after the alias is redefined, then the alias method refers to the original method, according to this feature, you can implement the technique of wrapping aliases:Class MyClass? ? Alias:real_length:length? ? def length? ? ? ? Real_length > 5? ' Long '

As an article of the College (http://xxwenda.com/article/584), the follow-up preparation is to be tested individually. Of course, there have been many tests. Apache Spark itself1.MLlibAmplabSpark was originally born in the Berkeley Amplab Laboratory and is still a Amplab project, though not in the Apache Spark Foundation, but still has a considerable place in your daily GitHub program.ML BaseThe mllib of the spark itself is at the bottom of the three-layer ML base, MLI is in the middle layer, a

3 Types of Learning3.1 Learning with Different Output Space YThe method of machine learning is categorized from the angle of the output spatial type.1. Two-dollar classification (binary classification): The output label is discrete, two-class.2. Multivariate classification (Multiclass classification): The output label is discrete, multi-class. The dualistic class

MATLAB machine learning did not see what tutorial, only a series of functions, had to record:Matlab Each machine learning method is implemented in many ways, and can be advanced configuration (such as the training decision tree when the various parameters set), here due to space limitations, no longer described in deta

Learning plan diagram of actual Java Virtual Machine (Understand Java Virtual Machine), Java Virtual Machine I don't want to talk about it anymore. I am actually using a Java virtual machine. I have to study hard and get started every day! Develop a

WEEK1:Machine learning: A computer program was said to learn from experience E with respect to some class of tasks T and performance measure P, if Its performance on tasks in T, as measured by P, improves with experience E. Supervised learning:we already know what we correct output should look like. Regression:try to map input variables to some continuous function.

"Machine learning" Matlab 2015a self-machine learning algorithm RollupAuthor: Chen Fa St. "Introduction"Today suddenly found that the version of matlab2015a with a lot of classical machine learning methods, simple and easy to use,

This set of tutorials is similar. Learn language in TDD mode. There are no books, the first is Ruby first out. The efficiency of self-clojure is the highest.
