Gamma function and Gamma Probability Distribution Gamma function and Gamma probability density both are very important concepts in mathematics and statistics. Furthermore, understanding Gamma function and Gamma probability density helps to understand chi-square distribution which plays very important role in machine learning. Especially, in Decision Tree Learning Chi-Square distribution used. In this post, I will […]

Improper Integrals In improper integral, either upper limit or lower limit tends to -∞ or ∞. Furthermore, both integrals may approach to infinity one negative infinity -∞ and other is ∞. Examples of improper integrals are  

Linear Programming Problem The problem of formulating an objective function and constraints an establishing relationship between variables is called a programming problem (LPP). If objective function and constraints are linear then the problem is called linear programming problem. Example- Sometimes, you come across the situation when you need to optimize your algorithm. If you can

Nested Lists in Python List in Python is a powerful data structure and it allows arbitrary numbers of nested lists in Python.  However, problems you will face to access them using loops. In this post, I have explained how to access nested list of elements. Suppose you have a nested list a=[3,5,8,4,15,34,[5,8,[-4,-8],9,3], 8,9,[6,9],12,7]. To understand

Principal Component Analysis(PCA) Principal Component Analysis (PCA) is an unsupervised machine learning feature reduction technique for high-dimensional and correlated data sets. Images and text documents have high dimensional data sets which requires unnecessary computation power and storage. Basic goal of PCA is to select features which have high variance. High variance of a feature indicates

Insertion Sort in Python Insertion sort examine the previously sorted sub-array and insert an element at its proper position. If you have an array a[0], a[1], a[2], a[3],……….a[n]. Then in insertion sort a[0] trivially sorted sub-array. Again compare a[0] to a[1] and if a[0]> a[1] exchange it. Now sub-array a[0],a[1] is sorted again compare a[2]

Inheritance in Object Oriented Programming Inheritance is the process of acquiring properties from a father class into a child class. Suppose there are two classes A and B, then if B acquires properties of A i.e variables and methods then B inherits A and this process is called inheritance.   Inheritance in Python Here a

Computer Vision- Computer Vision refers to enable computers to understand digital images and videos. Mathematical and signal processing knowledge can help a lot to understand computer vision study field. The computer vision study field requires acquiring information from digital videos and analyzing them using using machine learning, deep learning and other techniques. Moreover, Computer Vision

Selection Sort Selection sort uses statistical technique which finds minimum/maximum from a list and puts it at appropriate position. If you consider ascending order the smallest element will be placed at the first position, the second smallest element will be placed at the second position and the third smallest element will be placed at the

Binary Search Basic idea behind binary search is to divide sorted array in two parts, and check whether the element which divides the array is desired element . And if the desired element is found then stop the search, otherwise further divide the array until the desired element is not found. Step-Wise Pictorial Demonstration of
