The answer entirely depends - "Deliberately altering the model to produce equal results despite unequal patterns in reality" is so vague as to be meaningless in this discussion. > Is the goal of the AI model to predict crime ra

You are correct about the distribution of certain crimes, but you've entirely missed the point.* Problems like violence have multiple causes, but are widely understood to be linked to problems of poverty, inequality, and marginalizatio

I think you've very severely missed the point. Differences like those you describe generally reflect biases in our socal structure, which are then (correctly, but problematically) reflected in statistical models and algorithms of all s

So, a mathematical/statistical tool which usefully describe a variety of phenomena. I have no issue with that kind of framing.

So long as there's a positive carbon return on adding the extra infrastructure. There very well may be, but adding pipes to burn off excess methane is way easier than generating and transporting electricity.

I think it's fun, but I HATE that it has such a strong pay to win component. If a video game let players spend thousands of dollars on high power abilities to completely dominate the lower paid tier players, they'd be ridiculed in

The post I was replying to was attempting to make a much more general point - I understand the default as applied to Scikit Learn.

I think you're taking a perspective which is too focused on ML, ignoring the widespread statistical use of logistic regression in lower dimensional settings with reasonable a-priori covariate structures. > Logistic regression withou

I'm having trouble visualizing how this would be stable - from their reference frame (orbiting a Lagrange point), the pressure is coming unidirectionally. They'd be accelerated in one direction constantly, which seems like it coul

The carbon cost of manufacture and transport seems like it would absolutely dwarf any benefit to such a scheme.

Wouldn't solar radiation pressure blow them all over the place?

This gets repeated a lot, but it directly contradicts another bit of common wisdom: security by obscurity isn't. Not only are we vulnerable to a few key districts tipping elections, nation state actors should find it absolutely trivial

True, though I do think it's worth looking for connections between the two. A rail trail running through an area could form a good route for many different short commutes all along its length. If it's all rural, then sure - there&

No argument there, I just think it's also worthwhile from a quality of life + tourism $ perspective.

There is a huge range of electric bike products. When I'm old and have difficulty tackling the big hills in my area, I fully intend to get an e-bike just to give me a boost in those spots.

When comparing two alternatives, we can most definitely conclude that the science is settled, at least until actual evidence to the contrary shows up. Being open to accepting new evidence in the future in no way means we can't act conf

Climate models are a perfect example of the above statement. They're not good enough to predict the detailed future with certainty (weather forecasts only go out for a few days), but they're useful and valid for reasoning about la

Depending on how you look at "improvement", that's not strictly true. Often, large data sources are slightly biased relative to the population we want to generalize to (say, a single regional company's customers, trying

The point is - I didn't "ask" anybody to upgrade, this was pushed harder than a time share. How about I rephrase: "I felt lied to and taken advantage of, and I decided not to bother being a customer any longer, given tha

Perhaps it was 60. As I mentioned, I explicitly asked if I had to take any action to get the refund, and I was lied to.

Maybe it was 60. I literally asked the cashier: "I will not remember to request a refund. Will it be automatically credited to me if I do not meet the threshold?", and they told me yes.

I'm well aware, just wanted to point out a fact about an underappreciated ecosystem. I feel the same way when people complain about swamps.

For sure, I just don't think we should gloss over the nature of such ecosystems, since many people really don't know.
