Reads like fearmongering about oppressive and violent applications of AI that the Chinese government hypothetically could deploy, which the US government is already actively workin…

Only perfect multicollinearity (correlation of 1.0 or -1.0) is a problem at the linear algebra level when fitting a statistical model. But theoretically speaking, in a scientific c…

In other words, as economists say, because OLS is provably the BLUE (Best Linear Unbiased Estimator) aka the Gauss-Markov Theorem.

You make a good point, though the difference between ML and statistics isn't just about interpreting and validating the model. It's about the "novel discoveries" part aka Doing Sci…

> A sailor is sailing her boat across the lake on a windy day. As the wind blows, she counters by turning the rudder in such a way so as to exactly offset the force of the wind. Ba…

Collider bias or "Berkson's Paradox" is a fun one, there lots of examples of it in everyday life: https://en.wikipedia.org/wiki/Berkson%27s_paradox

Indeed, causally linked variables need not be correlated in observed data; bias in the opposite direction of the causal effect may approximately equal or exceed it in magnitude and…

This. I bought toothpaste on Amazon, used it up, and the next time I went to buy the exact same toothpaste, the price had doubled.

USPA has a tested division now and it's been gaining in popularity--it will soon be more popular than the untested division if it isn't already. Most of the top untested powerlifte…

Which is based not on your ability to produce value, but your ability to capture value and charge a cut of every unit, and is thus a massive disincentive to produce public goods.

When I lived in South Korea, one of the things that struck me was how much "flatter" the generations there were in terms of pop culture and music taste and awareness, compared to t…

My friend (who's the same age as me) has a 14 year old son who's learning guitar and he asked me for a lesson. The first thing he wanted me to show him was some riffs from AC/DC so…

I use plotnine whenever I need to make (static) plots in Python. It's really quite well done, a close match to R's ggplot2, and more feature complete than any of the other Python g…

I'm not sure I've even seen a recent, large C++ project that didn't depend on Python or some other external scripting language just to build it, so it's kind of hard to imagine usi…

Ever had a dry-aged steak?

It's a lot easier to go distributed if you're append-only, that's for sure.

Substances affect different people differently. I can have 3-4 drinks in an evening without changing my eating or sleep habits at all and without feeling any different the next day…

Yeah. When I run out, I just add it to my grocery list and pick up some more the next time I go to the supermarket. Can't remember the last time I left my house specifically to buy…

A drinking problem isn't defined by quantity, it is when you have a problematic habit/dependence that you can't quit at will. There are plenty of people who enjoy a few drinks seve…

Except for those people who wake up and have a midnight snack. Cutting out the snacking is probably also a major factor in the effectiveness of intermittent fasting, especially giv…

Power Pivot is the name for the tabular data modeling feature in Excel. It works similarly to Power BI or SQL Server Analysis Services, sharing the underlying database technology. …

Assuming the company has a Microsoft 365 subscription, Mac users can just use the Excel web client in their browser to access the data via pivot tables.

I agree and I do this via Power BI. If you import data into a Power BI report, create a data model with calculated measures (in DAX, not MDX), and publish it to the online service,…

Darts isn't a specific model, it's a wrapper API for a wide variety of forecasting models, and Prophet is one of them. Other models may or may not outperform Prophet depending on t…
