Thanks again to Pillar, Chris Baker, and Jeff for their generous hospitality.
They gave us free pizza, salad, cookies, and beverages.
We had around 46 people, probably the most at a COhPy meeting ever.
and we ran out of pizza and cookies for the first time.

Jason Green ran the meeting. He's great in front of a crowd.

Machine Learning (using scikit-learn)
by Jeff Klukas, Data Engineer at Simple.
dry run for PyOhio

came from academia
six years at University of Wisconsin

worked on large hadron collider

    (compare with Andrew Kubera's ALICE)

To get good answers, consider following the advice in the links below.

petabyte is 1000 (or 1024) terabytes
big data is not amenable to machine learning

wp:Simple (bank)
Works remotely for Simple which is based in Portland, Oregon.


    most slides were viewable from back of row with ambient light on screen

        low resolution
        good contrast but could be better

            black text would be better than gray text

    live demo had too much content on screen

        should be viewable from back of room
        24x80 would have best viewability

scikit-learn built on top of pandas, which is built on top of numpy
hope to classify texts from customers (triage)
especially urgent ones to reduce losses from fraud

split between data scientists and folks who apply found patterns

separate learning from serving

supervised learning

lemma is dictionary form of a word e.g. goes -> go
    how relevant would their pipeline syntax be to other stuff in python?

split data into training and testing

five data scientists
six data engineers

train on data that is only a couple megabytes
