Linear Regression for Machine Learning
Linear regression is the statistical technique to find relationship between two or more variables. To predict the values of response (target) variable based on that values of predictors (external / independent variables) we can use linear regression. Simple linear regression is having only one external factor while Multiple liner regression is having more than one…
Read MoreDifferent uses of underscore in Python
1 – Using in interpreter When you execute the expression in the python interpreter it will store the result of last executed expression in special variable that is underscore (‘_’). 2 – Using in looping While using loops or iterating over iterable objects you can use underscore (‘_’) as a variable. 3 – Using in…

Syntax: Assert condition [Error Message] Example 1: assert statement without error message Example 2: assert statement with error message Example 3: assert statement with try & except Example 4: assert statement with function Above, square(10) will return 100, whereas square(-10) will raise an AssertionError because we passed -10.

Read MoreDifference between iterables and iterators in Python
Iterables Iterators Iterators can be iterable because both iterator and iterable can be iterated using for loop but iterable objects can not be iterator because next() method is not supported by iterable objects. Popular Posts
Read MoreDecorators and Generators in Python
Python implementation Generators Python generators are functions that are similar to normal functions, but use yield statements instead of return statements. A generator function returns the generator object with a sequence of elements, which we can iterate over. Element in a generator object can be accessed either by using the next() function or using a…
Read MoreAbstraction in Python
Abstract Class Why Abstraction is Important? In Python, a person usually abstracts data/classes to hide the irrelevant information. This helps to reduce complexity and increase application efficiency. Abstract Base Classes An abstract class is the first part of a development interface that can be used to apply common features and behavior to several related subclasses.…
Read MoreOOPs in Python
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects which contains data or attributes and code or methods. Major oops concepts include Class, Object, Inheritance, Polymorphism, Data Abstraction, Encapsulation. Class Class is the user defined data type and it is defined using class keyword. It is a collection of similar type…

What is Edge detection? Edge detection is a computer vision technique that uses the edges of an image to find and extract objects. It is widely used in a variety of fields such as photography, video and computer vision. it is used in many ways in computer vision, including image segmentation, which divides an image…

In this article, I will be discussing about various algorithms of image feature detection, description using OpenCV. Introduction What do humans typically do when they see the image? He will be able to recognize the faces which are there inside the images. So, in a simple form, computer vision is what allows computers to see…

You may be already familiar with the word ‘contour.’ I’ve used this term several times in previous posts. A contour line is a curved line representing values. It is a very simple type of map that outlines the changes in an area, typically separating the different landforms. But then you may ask this. The terms ‘edges’…
