The Home Office hosed up here by having and "expert" systems type thing which was obviously racist, rather than some black box ml model which was also obviously racist as it used a history of home office decisions to train on, but you could maybe convince a court otherwise

Wheeee!
in order to proactively address the forecasted scourge of bot-generated content that will sweep the internet some new rules will be introduced for pstoing:

- all p0sts must be over 2048 words long, the approximate context window gpt-3 can keep track of. this number will be increased in the future as technology progresses
- pists must always end with a logical conclusion based on premises introduced throughout that pot, to further test comprehension of your own text
- postos should reference recent events and knowledge, preferably newer than a week, to require continuous retraining of models
- pick a word and consistently misspell it throughout the pst but never repeat the same spelling twice, we believe this will be hard for the current models to replicate
- if possible have two trusted forums members vouch that they watched you type out your ospt
- any self-contradiction will now be bannable as these kind of logic errors are common in neural network generated texts
- be sure to attend your local pgp key signing party in prepratation for web of trust which will be mainstream any day now

thus pasts should from now have word count above or equal to us covid deaths last weekend, or 75% of the tons of ammonium nitrate exploded in beirut, in order to combat bots and computer generated text

just fit a l1 regularized logistic regression model to whatever they want, thats machine learning and is far more likely to give accurate results than whatever deep learning neural network stuff they probalby have in mind

the whole "logits correspond to confidence levels" thing is pretty suspect

like you train the model to output 1 for the correct label and 0 for the other ones, usually with some sort of mean squared error. that's extremely not the same as outputting actual probabilities

nah that's a fine interpretation for a logit - you're explicitly modelling Pr(Y = 1 | X).

But is your model any good? Just cause you predict probabilities doesn't mean that your predictions aren't terrible.

ofc, but "is your model appropriate for the situation you're applying it to" and "assuming the model is appropriate and correctly specified, how do you interpret its output" are two separate questions.

I think there's still a lot going on in the planning and decision making categories, but a lot of that stuff isn't branded so much as AI. I don't really follow specifics but I think that recent advances in algebraic topology have had a big impact on route planning and similar problems.
