What to expect after completing a Data Science Certification Program?

1 in 3 ads we see now, sell ‘Certification Courses’ that would transform careers. There is hardly any talk about what to expect once we complete an online certification program/course, especially to change one’s line of profession.

How can I solve any question on finding the probability of an event in a job interview / written test? (Part 2)

Properties of probability i) 0 ≤ P(A) ≤ 1. ii) P(ɸ) = 0, P(S) = 1. iii) For any two events A and B, P(AUB) = P(A) + P(B) – P(A∩B), where AUB is read as ‘A

Web Scraping using Selenium

What is Web Scraping? Web Scraping is a popular methodology to extract data from websites. This is often done to derive insights for Sentiment Analysis, Predicting User preferences, Cross-Selling products, etc. Some of the real-life examples of

Outlier Detection in High Dimensional Data using ABOD

We know what outliers are – the data points that lie outside of where most of our data lie. When dealing with Outliers, it is relatively straightforward to find outliers in a uni-dimensional setting where we could

All the Numbers Behind the Decision Tree

In this article, we are going to see various numbers which we get as output after we implement a decision tree. Prerequisite Before you can start reading this blog we expect you to have these prior understanding

Outlier Detection in Time Series

Anomalies a.k.a Outliers are patterns in data which do not conform to the data points near to it.  Statistically, they are the data points that are deemed to belong to a different population. Timely detection of anomaly

Multi-Label Classification

Classification has been a go-to approach for various problems for many years now. However, with problems becoming more and more specific a simple classification model can’t be the solution for all of them. Rather than having one
