    Statistically, machine learning has poor modeling practices which should limit generalizability. It doesn't. Why? For tasks like image recognition, all humans on the ML team understand ground truth; in healthcare/science tasks, it won't be the same. We can expect lots of failure.

    A+ beautiful, a grand achievement by it is wonderful to see Byrne on clean background, all the original copies I saw over the years all had extensive foxing. In my Envisioning Information, we fully rebuilt 2 Byrne pages, hand-separated colors for printing.

    Let me get this straight: Sears has $25 million laying around to pay out executives who ran the company into the ground, but doesn't have any money to give the thousands of workers they laid off severance pay?

    Tonight’s ruling creates confusion, puts affordable health insurance at risk, and targets Americans with pre-existing conditions. The Supreme Court already upheld the law’s constitutionality — twice. Sign up tonight for 2019 coverage at .

    A couple days ago another team asked me to speak about Bayesian data analysis. I decided that instead of doing a nuts/bolts of how to fit/use Bayesian models, I would describe "Bayesian analysis: The Good Parts". <potentially controversial thread>
