When we read or talk about “data science”, most of the talk is around modelling - the maths behind it, the “cool” modelling techniques, what kind of CPUs or GPUs are required, and all that. What we normally talk less about is how data science interacts with business.
In this inaugural episode of Data Chatter, I talk to S Anand, co-founder and CEO of Gramener, about this so-called “interaction layer”. Our conversation is almost completely focussed on two such interfaces - Microsoft Excel, and data visualisation. We talk about various aspects of what it takes to communicate data to business, and pros and cons of different tools.
Anand is a co-founder of Gramener, a data science company. He leads a team that automates insights from data and narrates these as visual data stories. He is recognized as one of India's top 10 data scientists, and is a regular TEDx speaker.
