For time is the ultimate non-renewable resource! Data Science represents the convergence of Domain knowledge, Data Collection and a series of hypotheses validated or invalidated by use of Math. And Big Data Science takes that one step further into the realm of massive datasets that become necessary and pre-condition in Science and Business. So the […]

Last night, 0x offices were well populated with some very bright programmers. Big thanks to Cyprien Noel, the 0x hacker who designed k-means. He led the group as we collaboratively worked through building the code underpinning K-means modeling. In case you missed the group last night – we’re doing it again. In about a month […]

Every day as part of my 0x immersion program one of our hackers tries to explain something he is working on –  an especially beautiful bit of code or something about data science and how the mechanics of our project work, or whatever.  Every day, at least once, I am completely confused. I realize that […]

One of the (few) downsides of being in the Bay is the completely absurd traffic. Perhaps I am a bit more sensitive to this than most, given my epic daily commute.  While I am normally inclined to whine about my cross-bay traverse a little, yesterday it paid off.  You see, I’m used to making sense […]

BIG VS. LITTLE: P-Values and Coefficients
by H20.ai June 7, 2013 Uncategorized [EN]

The Quick and Dirty: For the moment let’s assume that we have some a priori hypothesis, and we want to test. We can talk about two things: how big the relationship is and how strong it is. P-values don’t care about big – they only care about strong. To get a sense for this recall […]

Chocolate Cake (Wednesday, June 5, 2013)  You know how sometimes you have one bite of really good chocolate cake, or a really amazing peach and totally assume that you could eat another 30lbs of whatever without regard for good manners or physical limitations?  Yeah. Decreasing marginal returns dictate that it almost always turns out that […]
