Dr. Z commented on Vincent Granville's blog post Example of Bad Data Science: Test of Hypothesis
"I agree completely. All these assumption-infested approaches that many "scientists" evangelize don't hold water when it comes to the real-world. An approach like the one you described is much more robust and sustainable. Still, I find…"

"Good job Vincent. I look forward to reading it. I'm sure it's better than John Foreman's book, which is IMO the best one out there at the moment."

Dr. Z commented on Vincent Granville's blog post The Data Science Equation
"Yes, statistics is generic indeed. Still, some data scientists include it as a skill, since it's something that potential employers are familiar with. Hilary is great. Her definition of the data product is probably the best out there."

Dr. Z commented on Vincent Granville's blog post Fast Combinatorial Feature Selection with New Definition of Predictive Power
"Don't get me wrong. I really would like to see this method in your book. I'm only asking for a reference to my work, which I have to say, took a lot of time and effort to do, considering my programming skills at that time."

Dr. Z commented on Vincent Granville's blog post Fast Combinatorial Feature Selection with New Definition of Predictive Power

Honeybees, Hive, and Presto

Posted on November 13, 2013 at 5:00am 0 Comments

Topic

Recently I've been pondering on the idea of synergy, which I relate to the Honeybee Effect. Also, somewhat related is Hadoop's module Hive, for querying large databases. Apparently, Facebook has made their own big data module for SQL-like queries (Presto) open-source about 7 days ago, making waves in the big data scene. What are your views on these matters?

Thanks

10 signs that you are a data scientist

http://ficolabsblog.fico.com/2013/10/top-10-ways-you-know-youre-a-data-scientist.html

I'd add an 11th one as well: you check data science sites before you check news sites in the morning!

10. You think … “So much data, so littl…”

9. You know what heteroscedasticity is.

8. Your best pick-up lines all include the word “moneyball.”

7. You look at your grocery…
