Data scientists use a range of tools in their work and some of these eventually require programming. This book, titled The Art and Craft of Computer Programming, is a guide to computer programming. It does not focus on a specific programming language, but instead contains the essential material from a first year Computer Science course. The book is available from Amazon.com.…

One of my favorite things over the year was starting a personal blog. (You can find my website here if you are curious.) How did it happen? Well, I was reading an article and one quote in particular really struck me: "it's not what you know it's who you know". 

That quote really resonates with me. Throughout my life I’ve learned a lot, and…

Most people think data science is smart people doing very smart stuff. Well that’s not it. Data science is just another subject involving its own bit of subtle complexities that has to be handled with knowledge and an innovative approach. JUST LIKE COOKING.

Getting the Data

Cooking is art and science. So is Analytics. Both start from getting the right ingredients. No matter how many spices and cooking techniques you apply, the dish won’t…

"Information is the oil of the 21st century, and analytics is the combustion engine" Peter Sondergaard, SVP, Gartner Research

In analytics, we retrieve information from various data sources; it can be structured or unstructured. The biggest challenge here is to retrieve information from unstructured data mainly texts. Here machine learning comes into the picture to overcome this challenge. Different algorithms have been designed in different platforms…

Disclaimer: This is my attempt to explain some of the ‘Big Data’ concepts using basic analogies. There are inevitably nuances my analogy misses.

What is HDFS?

When people talk about ‘Hadoop’ they are usually referring to either the efficient storing or processing of large amounts of data. MapReduce is a framework for efficient processing using a parallel, distributed algorithm…

You’re working on the MAIN MODEL. The one that leverages half the company’s assets, and on which your paycheck and that of many others depends. You’ve already run through a stepwise, forward, and backward search of the variables, their interactions, and possible curvatures. What are the most productive things to do next?

Here are a couple of ideas…

As R programming language becoming popular more and more among data science group, industries, researchers, companies embracing R, going forward I will be writing posts on learning Data science using R. The tutorial course will include topics on data types of R, handling data using R, probability theory, Machine Learning, Supervised – unSupervised learning, Data Visualization using R, etc. Before going further, let’s just see some stats and tidbits on data science and…

Recently I have come across a term, CRISP-DM - a data mining standard. Though this process is not a new one but I felt every analyst should know about commonly used Industry wide process. In this post I will explain about different phases involved in creating a data mining solution. 



CRISP-DM, an acronym for Cross Industry Standard Process for Data Mining, is a data mining process model that includes commonly used approaches that data…

The job of a data analyst nowadays has become very extensive, in its need to cover a number of different and ever-changing tasks.

A data analyst must query a variety of internal and external data sources, each with a different access protocol and format; integrate these data with results from REST and web services queried over the Internet, such as Google API or any social media channel; exchange information with business analysts, who, while lacking the deep mathematical background,…

Random Forest is a machine learning algorithm used for classification, regression, and feature selection. It's an ensemble technique, meaning it combines the output of one weaker technique in order to get a stronger result.

The weaker technique in this case is a decision tree. Decision trees work by splitting the and re-splitting the data by…

We all know that time is money, especially when you're paying a data scientist. But the New York Times reports that... 

"Data scientists, according to interviews and expert estimates, spend 50 percent to 80 percent of their time mired in [the] mundane labor of collecting and preparing unruly digital data, before it can be explored for useful nuggets."…

All of us at some point in the process of examining…
