Editor's Notes
- #5 Data cleansing, preparation, feature engineering. The dirty work we do all day at the insight factory.
- #7 Does everyone have to be a data scientist? Are there tools that can make anyone into a data scientist?
- #8 http://www.quora.com/What-is-the-difference-between-a-data-scientist-and-a-statistician
- #9 Data scientists can do two things better than data analysts: ask great questions and answer them faster than other people would think possible.
- #10 Everyone gets a Ferrari!
- #11 Oh no! Everyone has a Ferrari! Induced demand: as you increase the supply of something, the demand for it increases as well.
- #12 We need the equivalent of public transit infrastructure for analytic queries: low marginal cost for asking one more question, goes the places most people need to go, removes load from the roadways.
- #13 The spell correction example as a model for what the public transit infrastructure should look like.
- #14 Can we create a data model that makes this kind of powerful analysis available to people who only know SQL?
- #18 Even better, can a common data model enable us to seamlessly move models from the offline, analytical world to the online, operational world? Because the supernova data model is essentially the HBase/Cassandra/Mongo/etc. data model.
- #19 http://github.com/jwills/exhibit
- #20 No tool can make you a data scientist, because it’s the ability to push beyond the limits of your tools that makes you a data scientist.
