What can be predicted, and what can't?

Given the right data being correctly collected, and analyzed using sound predictive models, what can be predicted, and what can't be predicted no matter what?

Fallacy of Rational Prerequisite & My Fruitless Existence

Before elaborating on my fruitless existence - about my decision to avoid fruit - I want to emphasize how this blog is actually about something that I call the "Fallacy of Rational Prerequisite." There will be some misunderstanding about this term even after my prolonged explanation. I just want to state plainly at the outset that I am not proposing that people become irrational. If they are already so, I am not suggesting that they further the situation.…

Why Media Bias Has Nowhere to Run and Hide from Data Science

When you want to see the face of biased reporting in online news, you may not have to go further than, the satirical news site, The Onion. Titles such as “Media Reports of Bear Attacks May Be Biased”, “Weather Channel Accused of Pro-Weather Bias”, and “Media Criticized for Hometown Sports Reporting” can make us laugh, but they can…

The data science project lifecycle

How does the typical data science project life-cycle look like?

This post looks at practical aspects of implementing data science projects. It also assumes a certain level of maturity in big data (more on big data maturity models in the next post) and data science management within the organization. Therefore the life cycle presented here differs, sometimes significantly from purist definitions of 'science' which emphasize the…

Can Analysis be Open-Source?

Over the past year, as the head of analytics at a tech startup, I've had many conversations with analysts about what they want to learn from their data. Perhaps unsurprisingly, a lot of companies have similar questions—What drives retention? How do customers interact with products? How do we better understand sales pipelines? What's the lifetime value of a user?

These questions were familiar to us and we'd worked on many of them ourselves. To find answers in our own data, we wrote…

Rules for building a Data Product in IT organizations

Best solution to a problem: data science versus statistical paradigm

The definition of 'best' depends on which school you follow. Data science and classic statistical science are at the opposite ends of the spectrum. So let's clarify what 'best solution' means in these two opposite contexts:

'Best', according to statistical science:

  • It usually means the global maximum of a mathematical optimization problem
  • The objective function involved is usually a maximum likelihood function, KS, c-statistics, or some function…

How-to use Bag of little bootstraps Methodology to Compute Error Bounds on Machine Learning Tasks

We all know that calculating error bounds on metrics derived from very large data sets has been problematic for a number of reasons. In more traditional statistics one can put a confidence interval or error bound on most metrics (e.g., mean), parameters (e.g., slope in a regression), or classifications (e.g., confusion matrix and the Kappa statistic).

For many machine learning applications, an error bound could be very important.…

Our iceberg is melting . Now where's that data scientist?

On the face of it, John Kotter’s seminal book “Our iceberg is melting” is a simple tale of a group of penguins who are scared about losing their home, their iceberg, and yes, even more scared of the changes that could entail. But through that simple story and their struggle for finding their new home, the story delivers a more powerful message that…
