Although nothing really changes except for the date, a new year fills everyone with the hope of starting things afresh. Adding a bit of planning, well-envisioned goals and a learning roadmap makes for a great recipe for a year full of growth.

This post intends to strengthen your plan by providing you with a learning framework, resources, and project ideas to build a solid portfolio of work showcasing expertise in data science.

Disclaimer:
The roadmap defined is prepared based on my little experience in data science. This is not the be-all and end-all learning plan. The roadmap may change to better suit any specific domain/field of study. …


A list of topics to kickstart your journey towards becoming a Data Scientist in Finance

Back when I was working as a Systems Development Engineer at an Investment Management firm, one thing that I learned is that quantitative finance needs you to be good with mathematics, programming, and data analysis.

Algorithmic or Quantitative trading can be defined as the process of designing and developing statistical and mathematical trading strategies. It is an extremely sophisticated area of finance.

So, the question is how does one get started with Algorithmic Trading?

I am going to walk you through five essential topics that you should start with in order to pave your way in this fascinating world of trading. I personally prefer Python as it offers the right degree of customization, ease/speed of development, testing frameworks, and execution speed, therefore, all these topics are focused on Python for Trading. …

It’s only in hindsight that you can tell how your decisions and action plans have turned out.

I am a big-time consumer of self-help content — books, podcasts, blogs, newsletters, I have been intoxicated with nearly all sorts of resources.

I enjoy making new year resolutions but I never deeply examine the gross outcome of this habit of mine. So, here I am looking over my failures, achievements, and struggles of 2020.

Where am I in my career?

Before I start reviewing the year, it’s important to set the context and for you to have an idea of where my thoughts are coming from.

I left my first and only job in August 2018. …


AI updates from November + books, datasets, research papers that are worth your time

So, November is over and I’ve come across a good list of blogs, research papers, books, and datasets that are worth deep-diving into.

This is the second part of the AI Monthly webcast, you can find the first one here.

Here’s what we are going to cover in the November AI updates:

Firstly, we’ll look at 2 interesting pieces of news that you’d have heard:

  1. The first one comes from DeepMind. The latest version of their AI system AlphaFold has been recognized as a solution to figuring out the shape of protein structure in 3D.
  2. The second is for TensorFlow users of Intel Macs or Macs powered by Apple’s new M1 chip can now take advantage of accelerated training using Apple’s Mac-optimized version of TensorFlow 2.4 and the new ML Compute framework. …


A guide to discovering normal distribution and calculating key estimates of location & variability with Python

This is the second blog in the Stats series after explaining the taxonomy of data in the first blog. Here, we’ll learn to apply a few essential foundational concepts that help us describe the data using a set of statistical methods.

A sample is a snapshot of data from a larger dataset; this larger dataset which is all of the data that could be possibly collected is called population. In statistics, the population is a broad, defined, and often theoretical set of all possible observations that are generated from an experiment or from a domain.

These observations in the sample dataset often fit a certain kind of distribution which is commonly called the normal distribution and formally called Gaussian distribution. It is the most studied distribution because of which there is a subfield of statistics simply dedicated to Gaussian data. …


Understanding the taxonomy of data types

After making the need for statistics in data science apparent in my previous blog, it’s time to dive right in and get hands-on with understanding the statistical methods. This is going to be a series of blog posts and videos(on my YT channel).

Who are You?

I am starting this series of blogs on statistics and probability to help all the coders and analysts understand these concepts and methods. You are someone who is familiar with Python programming and is trying to get a better grip over statistics to master Data Science skills.

Growth of Data & Data Analysis

We know that Data Analysis has evolved beyond its original expected extent and this has happened because of the rapid development of technology, generation of more and bigger data, aggressive usage of quantitative analysis across a variety of disciplines. …


A monthly webcast where I share five cool projects worth spending time on!

The world of AI and Data Science is accelerating at an alarming rate. It becomes very hard for AI enthusiasts and learners to keep abreast of meaningful advances in the field. Applications, Research & Development, individual projects, proprietary software — every sector is applying DS and AI in its own remarkable way.

There are two main reasons I am starting this monthly AI webcast:

  1. This approach has helped me spot the trend in this broad domain of AI which reassures me of the direction I am moving in. So, why not share it with others!
  2. It fills me up with energy and gratitude that I am a part of this community. It also implies that I have a responsibility towards others who are struggling to showcase their talent and hard work to a wider audience. …


Answering important questions by transforming data into insights with Statistics

In this hyper-connected world, data is being generated and consumed at an unprecedented pace. As much as we enjoy this superconductivity of data, it invites abuse as well. Data professionals need to be trained in using statistical methods not only to interpret numbers but to uncover such abuse and protect us from being misled.

Not many data scientists are formally trained in statistics and there are very few good books and courses that offer to learn these statistical methods from a data science perspective.

Through this post, I intend to shed some light on

  • Why statistics — common misconceptions regarding learning…
