    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.

    It's a big stretch to put such a positive spin on the wastage of resources that occurs when the scientific pathway is led astray building upon results that can't be replicated.

    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.

    I recreated Byrne's 1847 edition of Euclid's Elements including interactive diagrams, cross references, and a new poster of all the original illustrations: Plus an in-depth blog post on how it was made:

    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>
