Everyone gets sunk by office politics at some point in their career, but data scientists are in some ways especially ill-prepared to navigate the unspoken rules and hidden agendas that together form a critical part of the corporate world. Although some people may actively fuel office politics to gain power, I'll assume that's not the case for most of us. I'd like instead to simply suggest a few basic survival skills, so we can focus as much as possible on…Continue

R language is the world's most widely used programming language for statistical analysis, predictive modeling and data science. It's popularity is claimed in many recent surveys and studies. R programming language is getting powerful day by day as number of supported packages grows. Some of big IT companies such as Microsoft and IBM have also started developing packages on R and offering enterprise version of R.

As an analyst, our first reaction when we get the data to analyse is to ask an ETA. Then we plan to attack the data left-right-centre and crush the maximum juice out of it with an exhaustive list of analysis techniques.
Oh dear, we got it all wrong!
This approach might get 50 slides to present the analysis but would miss on the most crucial aspect of any analytics engagement: a buy-in from the business folks. Because, since the start, the target of the whole analysis was data,…Continue

Many organizations are associating data monetization with selling their data. But selling data is not a trivial task, especially for organizations whose primary business relies on its data. Organizations new to selling data need to be concerned with privacy and Personally Identifiable Information (PII), data quality and accuracy, data transmission reliability, pricing, packaging, marketing, sales, support, etc. Companies such as Nielsen, Experian and Acxiom are…

This shinyapp is a live shiny/R web application (hosted on shinyapps.io) that implements simple sentiment analysis POC with R, to have an insight about the people's sentiment about the smartphones from different brands released in India for a couple of weeks over a past time period, it was written a few years back (in 2014), for demonstration purpose, with the tweets…Continue
Here I discuss four interesting mathematical problems (mostly involving famous unsolved conjectures) of considerable interest, and that even high school kids can understand. For the data scientist, it gives an unique opportunity to test various techniques to either disprove or make progress on these problems. The field itself has been a source of constant innovation -- especially to develop distributed architectures, as well as HPC (high performance computing) and quantum computing to try to…Continue

You won’t be able to get a job in data science if you can’t demonstrate the skills…Continue
In this article, the clustering output results using Spectral clustering (with normalized Laplacian) are going to be compared with taht obtained using KMeans clustering on a few shape datasets.

Artificial Intelligence (AI) is everywhere these days. It’s simultaneously heralded as both the greatest thing since sliced bread — freeing us from driving cars, diagnosing diseases better, and so on — and the worst thing imaginable— displacing millions of jobs, and a step towards the inevitable AI domination of humans.
Lost in this hyperbole are the many simple, yet effective, enabling innovations that AI makes possible. Just like we rely on machines in…Continue

In ordinary linear regression, we are estimating the mean of some variable y, conditional on the values of independent variables X. As we proceed to fit the ordinary least square regression model on the data we make a key assumption about the random error term in the linear model. Our assumption is that the error term has a constant variance across the values of independent variable X.
