from sklearn import svm X = [[1, 2], [3, 4]] #Training Samples y = [1, 2] #Class labels model = svm.SVC() #Making a support vector classifier model model.fit(X, y) #Fitting the data clf.predict([[2, 3]]) #After fitting, new data can be classified by using predict()

The procedure to perform a RMQ is already shown in introduction. The pseudo-code for checking Range Minimum Query will be: Procedure RangeMinimumQuery(SegmentTree, qLow, qHigh, low, high, position): if qLow <= low and qHigh >= high //Total Overlap Return SegmentTree[position] el...

Collection Operators can be used in a KVC key path to perform an operation on a “collection-type” property (i.e. NSArray, NSSet and similar). For example, a common operation to perform is to count the objects in a collection. To achieve this, you use the @count collection operator: self.array = @[@...

The following Codes can be found from Weka course Given iris.arff is loaded in weka, inside Weka Explorer's R console or Weka KnowledgeFlow's R Scripting, you can play with the following codes to make beautiful plots: library(ggplot2) ggplot(rdata, aes(x = petallength)) + geom_density() ...

Implementation of the Caesar cipher. This implementation performs the shift operation only on upper and lower case alphabets and retains the other characters (such as space as-is). The Caesar cipher is not secure as per current standards. Below example is for illustrative purposes only ! Refer...

The following methods can be used to generate a tree naturally (as if it was grown from a sapling) into the world. boolean generateTree(Location loc, TreeType type); boolean generateTree(Location loc, TreeType type, BlockChangeDelegate delegate); Location is where you want the tree to spawn ...

Where we came from Sometimes we can't provide all of the required metadata needed for the XmlSerializer framework in attribute. Suppose we have a base class of serialized objects, and some of the derived classes are unknown to the base class. We can't place an attribute for all of the classes which...

Unary operators are operators with only one operand. Unary operators are more efficient than standard JavaScript function calls. Additionally, unary operators can not be overridden and therefore their functionality is guaranteed. The following unary operators are available: OperatorOperationExampl...

In Production its good practice to secure your data and only allow operations on it to be undertaken via Stored Procedures. This means your application can't directly run CRUD operations on your data and potentially cause problems. Assigning permissions is a time-consuming, fiddly and generally oner...

What is tidyverse? tidyverse is the fast and elegant way to turn basic R into an enhanced tool, redesigned by Hadley/Rstudio. The development of all packages included in tidyverse follow the principle rules of The tidy tools manifesto. But first, let the authors describe their masterpiece: The t...

To update a specific program: sudo pacman -S <programName> To update entire the system: sudo pacman -Syu

Below there is the implementation in Java using a generics approach. It is the same algorithm, which is presented above. public interface InPlaceSort<T extends Comparable<T>> { void sort(final T[] elements); } public class MergeSort < T extends Comparable < T >> implem...

This is not something you will see in other programming environments. I came across it some years back and I couldn't understand why it was happening, but after working with MATLAB for some time I was able to figure it out. Look at the code snippet below: for x = 1:10 for x = 1:10 fpr...

set clipboard=unnamed This makes it possible to copy/paste between Vim and the system clipboard without specifying any special register. yy yanks the current line into the system clipboard p pastes the content of the system clipboard into Vim This only works if your Vim installation has cli...

Method Overriding and Overloading are two forms of polymorphism supported by Java. Method Overloading Method overloading (also known as static Polymorphism) is a way you can have two (or more) methods (functions) with same name in a single class. Yes its as simple as that. public class Shape{ ...
