Job Comparison – Data Scientist vs Data Engineer vs Statistician

Data Science is a flourishing industry. Countries and companies around the world are continuously experiencing a rush in the amount of data collected. They are determined to hire experts who can work on their data and improve their lives. Such experts are known by many names. Most popular being, ‘Data Scientist’. Among others include Data Engineers, Data Architects, Statisticians etc. But, how many of us are clear about the difference in these roles and designations? As I’ve experienced, people are confused between a Data Scientist, Data Engineer and Statistics. Some end up concluding, all these people do the same job, its just their names are different. I got astonished at hearing such answers. With these thoughts in mind, I decided to create a simple infographic to help you understand the job roles of a Data Scientist vs Data Engineer vs Statistician. This will help you to decide the best job role for you in coming future.

Theoretical Motivations for Deep Learning

Deep learning is a branch of machine learning algorithms based on learning multiple levels of representation. The multiple levels of representation corresponds to multiple levels of abstraction. This post explores the idea that if we can successfully learn multiple levels of representation then we can generalize well. The below flow charts illustrate how the different parts of an AI system relate to each other within different AI disciplines. The shaded boxes indicate components that are able to learn from data.

Statistical Tests: Asymptotic, Exact, ou based on Simulations?

This morning, in our mathematical statistics course, we’ve been discussing the ‘proportion test‘, i.e. given a sample of Bernoulli trials …

Julia: Compose3D.jl and ThreeJS.jl – Interactive 3D Graphics in the Browser

Over the last three months, I’ve been working on Compose3D, which is an extension of the amazing Compose package to 3D. My work on Compose3D began as a project for my Computer Graphics course along with Pranav T Bhat, and by the end of the course, we had a working prototype for Compose3D with support for contexts and geometries and a very basic WebGL backend.

QuantumPlots with ggplot2 and spatstat

Lately, I was plotting, comparing and trying to make a sense out of a lot of spatial statistic functions. To facilitate the procedure I wrote the following function to create a plot for the spatstat class ‘fv’, combined with ‘Quantum Plots’.
