Frequency distribution in statistics refers to a graph or table which depicts or illustrate the occurrences of values. Frequency distribution is very important in study of statistics, machine learning and data science area. To understand frequency distribution you have to understand organization of data. Basically, there are three types of data organization techniques. 1- Individual […]

Vector Space- A set V is called vector space on which two operations are defined. 1- Vector Addition 2- Scalar Multiplication Further, vector addition must follow the following properties and laws for vector addition. 1- Closure Property If u and v are two vectors in V then u+v must be in V. 2- Commutative Law

To understand random variable first you have to know about events. I will make you understand using examples. What are events? Example Tossing three coins on which one head turns up {HT,HH} A random variable quantify events of occurence. In other words, a random variable X is a function from set of events to real

Mutually Exclusive Events- Two or more events events are said to be mutually exclusive if only one can happen at a time. Example-1 In tossing a coin, event of tail up (T) and even of heads up (H) can not happen simultaneously. They are mutually exclusive events. Example-2 In rolling of a dice, event of

Linear Independence of Vectors Suppose α1, α2, α3, α4…………αn are vectors of V(F) where F is field. And there exist scalers a1, a2, a3, a4………..an which belong to field F. α1, α2, α3, α4…………αn vectors are called lineary independent if a1 α1 + a2 α2 + a3 α3+ ……… + an αn = 0 and

Often students get confused what are differences between divide and conquer and dynamic programming. Since they solve problems in similar nature. Divide the problem into sub-problems combine them to get solution. Here I list the differences between divide and conquer and dynamic programming in a table and also made quizzes so that you can practice

Mathematics is an essential part for machine learning without maths it is hard to get into core concepts. In addition, machine learning uses concepts from different branches, however, these branch of mathematics are the backbone of the machine learning. 1- Linear Algebra Matrix, Vector Spaces and Linear Transformations, Eigen Values and Eigen Vectors ( Principle
