  • 9. Making Data Science Work

    Everyone wants to do “data science”. Companies want to introduce “machine learning” in their products. Most fund raises by startups nowadays are accompanied by a statement of intent to invest in data, and data science.

    Back in 2006, mathematician Clive Humby, who was working for Tesco, made the statement that “data is the new oil” (to give context, we were in the middle of a massive bull run in oil prices then). And so companies are investing in data.

    However, just investing in data capture and hiring data scientists is not enough for a company to get value. It is important to structure the relationship between data and business, and how the data team is managed, in the right way for the data team to be effective.

    Today’s guest is Anuj Krishna. Over the last 14 years, Anuj has worked with multiple enterprises on both, the translation side as well as the execution side of analytics. He has helped create standard processes for analytical problem solving that are in use in multiple enterprises.

    Anuj was an early employee of MuSigma, and then went on to co-found TheMathCompany. In his current role, Anuj is Head of Assets at TheMathCompany, and is also responsible for operations related to TheMathCompany.

  • 8. Data Science For Babies

    There is an ongoing debate on when children should be taught to code. There is one group of people which insists that computer programming is a lifelong skill, and is best taught early. The opposing argument is that coding is possibly a fad, and that children will learn it when they have to.

    But what about data science? The field itself is less than 15 years old. Does it make sense to introduce it to children at an early age?

    According to Rahul Raghavan, the guest on this episode, the answer is an overwhelming “yes”.

    Rahul is a Montessori educator and founder of pep School v2, a Montessori school in Bangalore. Before getting into education, he was in the corporate world, working in impact investing (with VentureEast) and then with Amazon.

  • 7. From Random Walks to Random Forests: Analytics and data science on Wall Street

    One of the first industries to extensively use advanced maths to do better was financial services. Ever since Fischer Black and Myron Scholes published their seminal paper on option pricing in 1973, Wall Street firms hired mathematicians and scientists by the droves, getting them to model asset prices in order to get an edge in the market. Even today, top hedge funds such as Renaissance, Citadel and Two Sigma prefer to hire scientists rather than finance professionals to manage their portfolios.

    However, in the last decade or so, as Data Science and Artificial Intelligence have taken over the rest of the world, Wall Street has not maintained its leadership position in the use of maths to make money. How and why did this happen?

    In order to understand this, we talk to Hari Balaji, co-founder of Romulus, an award winning unstructured data automation platform for Financial Services firms.

    Prior to founding Romulus, Hari spent a decade in quant & data roles at Goldman Sachs across Hong Kong and Singapore. Hari is an alumnus of IIT Madras & IIM Ahmedabad.

  • 6. Manhattans and Moneyball to Kabaddi: How analytics evolves with sports

    For a lot of people, their first introduction to data and analytics happens through sport. Fans have tracked batting and bowling averages for many decades now. In the 1990s, with the coming of satellite TV in India, cricket fans had their first brush with bar graphs and line graphs, with “manhattans” and “worms” respectively.

    In the last two decades, following the publication of Michael Lewis’s Moneyball, the field of sports analytics hsa exploded. A couple of months before this podcast was released, it was revealed that footballer Kevin De Bruyne had hired a sports analytics firm in order to better negotiate his contract with Manchester City. And along the way, analytics has entered smaller sports such as kabaddi and volleyball.

    Today’s conversation is a double header, featuring the husband-wife duo of Arvind Sivdas and Dhanya P, who are also founders of KabaddiAdda, a Kabaddi platform. They have worked in analytics in cricket, badminton, volleyball and kabaddi, among other sports. We talk about the evolution of sports analytics, how to quantify “continuous sports”, the role of fantasy sport and several other things.

  • 5. Conjoints and Coupons: The evolution of quantitative marketing

    In business schools in India, there is a misconception that marketing is not quantitative, and that it is for the more “creative” people. However, if you look at its history, marketing has always been a highly quantitative subject.

    To know more about data and quant in marketing, we talk to Prithwiraj Mukherjee, an assistant professor of marketing at IIM Bangalore.

    Prithwiraj teaches marketing management and marketing research at the MBA and doctoral levels. His MOOC titled Quantitative Marketing Research is available on EdX and Swayam. He research interests include behavioral decision making where he models biases, and digital marketing where he investigates influencer fraud and clickbait.

    Prithwiraj has a PhD in marketing from ESSEC in Paris, and degrees in chemical engineering from NITK Surathkal and IISc

  • 3. Make BI Great Again

    “Business intelligence” has become a rather unfashionable term in the world of data and analytics. From generating buisness insights from intelligent use of data, it has largely devolved to become a software engineering function - to connect databases to front end tools.

    However, there is far more to business intelligence than just writing queries. In this episode, Karthik talks to another BI professional - Balaji Kuppuswamy, director of BI products at Youtube. They talk about what BI really is, the skills involved in BI, where it sits in an organisation, and how it can truly add value.

  • 1. Excel-lent Graphics

    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.

    Show Notes:
