But also, stop telling people how good it is up north, the southerners will ruin it

How on earth do you make it up north the exact week I go on holiday?

If you can, go it to roker beach and fausto coffee shop, especially if you have the dog with you

I couldn’t wait to get back to my wild rogue rampage of hitching rides on bot-piloted transports and watching my serials.

If you're still dichotomising continuous variables, stop.

Dichotomising your exposure &/or outcome wastes power.

Dichotomising confounders introduces residual confounding.

If a variable has non-linear effects, use splines!

If you want 'clinically relevant' threshold effects, use marginalisation.

That's a decent expectation - that priors get sharper with more experience - but it's an assumption that's fairly easy to violate.

The first one absolutely, the second one depends on your model of the world and the priors in it IMO

And a below inflation pay rise hurts like a kick up the posterior

6 days ago 1 0 1 0

The classic example I like to use to illustrate this is that I expect a pay rise every year, and if I don't get one I am disappointed.

My prior is on the trajectory, not the absolute value. And I don't like it when I get data that contradicts my prior πŸ˜…

Previous active inference formulations focused on stationary distributions, but more recent path based formulations handle dynamic environments much better.

Whether they actually correspond to human behaviour in my opinion the jury is still out

Rob I did not expect active inference to come up in a uk politics thread! πŸ™ŒπŸΎ

I would challenge that we are default biased away from change - we are default biased by our priors, which could be for a changing environment (but they don't have to be)

It would be nice if they interviewed 1400 people who don't have a house but would like one

I finally thought I understood the Monty Hall problem (kinda) and then I saw it in DAG form and now I'm pretty sure I neither understand the Monty Hall problem nor DAGs.

It makes sense if:
- you might want to swap one of those sub-functions out for another (e.g. a different algorithm implementation)
- it makes it easier to write tests (likely but not guaranteed)

But I think it really needs to be an extended period of time, one where it's long enough that there is actually a system in place to continue your work whilst you're gone, rather than you just be anxious that there will just be a larger pile waiting for you when you return

Double-take detail in this interview with Edith Heard, head of the Crick

Her French husband decided against getting a spouse visa because of the UK's "intrusive" immigration rules

If that's happening with one of the UK's most senior scientists, how many others are being put off completely?

I think I can offer a partial explanation, as yer resident anti-AI understander.

Programming is wizardry: you go to school, you read the books, you learn the arcane languages.

Using AI is like being a warlock, making a deal with a demon to do the things you can’t do. And who knows the cost?

This is something I used to do - intellectually someone might know that self-harm is bad, yet they still feel an overwhelming urge to do it.

Swapping to physical discomfort was (for me) a way of tricking my own mind into accepting the urge was satisfied without doing permanent damage
