A Live Introduction to Data Science: Naive Bayes and Holt-Winters Forecasting

3/12/2014

A month ago I spoke at Strata Conf in Santa Clara. Unlike my usual talks, this one was a 3 hour tutorial taken from my book, Data Smart. Specifically, I spent 3 hours doing chapter 3 and an abbreviated chapter 8. On the whole, I think it was a useful session, so I've posted it online so anybody can follow along.

Chapter 3 is an introduction to supervised machine learning via naive Bayes. And Chapter 8 is demand forecasting using triple exponential smoothing (Holt-Winters).

The first 5 minutes of the first video have garbled audio, but the tech fixes it before too long. My apologies.

To follow along, download the spreadsheets for chapters 3 and 8 from the downloads section of the book's website:

You'll need to unzip these spreadsheets and clear some data out of them per my instructions in the talk. Also, you'll need access to spreadsheet software.

The $30/hr Data Scientist

Yesterday a journalist asked me to comment on Vincent Granville's post about the $30/hr data scientist for hire on Elance. What started as a quick reply in an email, spiraled a bit, so I figured I'd post the entire reply here to get your thoughts in the comments.

When we ask the question, "Can someone do what a data scientist does for $30/hr?" we first need to answer the question, "What does a data scientist do?" And there are a multitude of answers to that question.
