Innovation Nation: AI godfathers gave Canada an early edge β€” but we could end up being left in the dust

"Canada is hanging on to the lead by 'our fingernails' as the gold rush to commercialize artificial intelligence goes global"

In the context of algorithm fairness in AI. From the O'Reilly Data Show podcast, Sharad Goel says: "You need domain expertise. There's no silver bullet. There's no black box you stick your algorithm into and it gives you thumbs up or down. It always depends on domain and context".

Examples in the podcast and paper are from loan approvals and the elusive idea of "fairness".

It's encouraging that people are socializing the challenges and limitations of data driven approaches and the role domain context plays in it.

This also has ramifications for organizations trying to create effective analytics strategies: it's hard delegate analytics because the needed domain context originates outside of the analytics space (which also explains why outsourcing analytics/data science offshore has not been successful).

Finally, on the idea of fairness, it's worth pointing out this is a bit if old news. Thomas Lumley points out in a similar article "This is old news in medical diagnostics, but appears not to have been considered in some other areas".

πŸ’‘ What is multi-armed bandit testing and why is it useful?

Multi-armed bandit (or simply "bandit") testing is similar to multivariate and A/B testing, but the sampling distribution for variants change gradually over time as feedback is received.

For example, with traditional A/B tests, we could test 2 email subject lines: A and B. We would initially send out emails to 200 customers, sending 100 A variations and 100 B variations. After some set period of time, say 24 hours, we would observe which email variant was opened by more customers. We would then send that variant to all customers moving forward.

With bandit testing, we would set some learning rate for the distribution of variants to change over time. Perhaps 60 customers opened the A variant emails and only 50 customers opened the B variant emails. We could then shift the distribution from (50% A, 50% B) to (55% A, 45% B) for the next round of emails.

Using this approach, we can continuously monitor the response from our audience and shift our actions accordingly. This is particularly useful in marketing or any industry where people's preferences and opinions may change rapidly since it continuously tests and learns preferences and can adapt very quickly.

The complaints "Python is slow" or "Python is unsafe" seem misguided. The point of Python isn't to be fast or safe, it's to be flexible and hackable, and to interface well with everything else. It has become successful by serving as a frontend from which to call other libraries.
#Python is more of an interface than it is a development language. It's a UX.

I may be wrong, but I get the impression that some data science people believe regression comes in just two flavors - OLS linear and binary logistic.

Setting aside the relationship between neural nets and regression, and that VAR, GARCH, Structural Equation Models and numerous other statistical models are really forms of regression, I have no idea how many kinds of "regression" are in common use.

"Dozens" would probably be an underestimate. There are countless other types which are used infrequently but essential in certain circumstances, like a fifth pitch in baseball.

Moreover, there is usually more than one way to estimate most statistical models. It's not unusual for a statistician to run one kind of regression model several ways with maximum likelihood estimation (MLE) and Bayesian alternatives, for example.

We have a BIG regression decision tree, and our choices are seldom inconsequential.

Left: how you would plot the Xception architecture in a paper.
Right: how you would implement it with the Functional API (that's the entire code).

1:1 match between how you think about it and how you write it.
