Totally - I used to work as quant for a boutique asset manager and the whole business was running on spreadsheets. Insane. Ended up putting it all in a database and developing an excel add-in to pull it from the database as array formulae.

I think there should be SAAS pricing style "packages" curricula like 1 week version learn ABC by reading XYZ, 4 week version, 6 month version, etc People generally think in terms of how much time they have - these lists are great

Very cool but wouldn't say simple haha! I implemented a Hough circle detector in JavaScript that might be of interest - it's got UI to tweak the accumulator threshold and is all first principles without any calls to black box func

Yes! The approach I took was to build a product that solves a broad problem (in my case geographic visualisation) and showed that to get clients who wanted something similar but tweaked for their use case. Of course they then ask 'is

Yes, I got a data science job advertised as masters only by showing past work and painting a picture of how I could do similar for their industry specific problems. I think credentials are often more a factor in getting the interview which

Awesome! The GIF is great but would really love a link to a live demo to play with :) Didn't know could do heatmap via leaflet - does it respond to crossfilter filtering?

there are a lot of gotchas that don't seem like errors but completely invalidate analysis when done without a thorough understanding of a technique. For example you can learn regression from a stats textbook but unless you've gone

It's lambda - basically the amount of regularization (simplification or 'overfit penalty') to impose. Usually chosen by cross-validation - try every lambda between say 0 and 10 in 0.5 increments and choose lambda that gives t

Would love to hear replies on this - just because it's against their terms of use, does that mean it's illegal? Just because someone says they don't want you to look at them and write down what you see doesn't make it il
