KNN in Machine Learning (from Scratch !!)
KNearest Neighbours: Introduction Birds of a feather flock together. William Turner The above quote perfectly sums up the algorithm that we are going to talk about in this post. KNN stands for KNearest Neighbours. It is a simple, easytoimplement supervised machine learning algorithm that can be used to solve both classification and regression problems. Note: […]

Data Science Starters
So, this post is for someone who wants to learn Data Science but is not able to find where to start from. In this post, I will share some crucial resources (free) that would help you get started with your Data Science journey, Programming So, to get started with Data Science you must be fluent […]

Heteroscedasticity
In this post, I want to talk about Heteroscedasticity. I can understand, some of you might have a hard time pronouncing it (atleast I did). Anyway, we are more interested in its meaning and it’s application rather than its pronunciation. So, Heteroscedasticity means the variability of a random disturbance is different across a vector. Now, […]

Linear Regression in Machine Learning (from Scratch !!)
Introduction In this post, I will talk about one of the most crucial techniques in Regression Analysis/Machine Learning, called Linear Regression. As per Wikipedia, Regression Analysis is defined as a set of statistical processes used to estimate the strength of the relationship between a dependent variable and an independent variable. The process which tries to […]

How to achieve multiple offers in Data Science as a College Student…
Introduction First of all, I would like to introduce myself. My name is Chitwan Manchanda and I am currently pursuing B.Tech in Mechanical Engineering from Delhi Technological University. I have offers from Simpl, Editorialist YX and Slice for Data Science roles. I was in my penultimate year when the Covid19 Pandemic hit and we all […]

Hypothesis Testing
In statistics, hypothesis testing is a form of inference using data to draw certain conclusions about the population. First, we make an assumption about the population which is known as the Null Hypothesis. It is denoted by H₀. Then we define the Alternate Hypothesis which is the opposite of what is stated in the Null Hypothesis, denoted by Hₐ. After defining […]

Customer Segmentation
Introduction Customer Segmentation is the process by which you divide your customers based on common characteristics and behavior. It is a subpart of the bigger niche called Customer Personality Analysis. Customer Personality Analysis is a detailed analysis of a company’s ideal customers. It helps a business to better understand its customers and makes it easier for them to modify products […]

Vegetable Image Classification using CNN
Introduction The human brain has specialised visual, auditory and other sensory modules. We want to mimic these specialised modules using Artificial Neurons and want to create what is known as Artificial Intelligence. The Convolutional Neural Network or CNN helps machines to recognise visual patterns, objects, images etc. CNNs emerged from the study of the brain’s visual cortex and have been used in […]
