Oh goody. Just thought of another amazing use for ai! You could use it to figure out the maximum length and interest a single borrower would be expected to pay and set the terms on that! Wunderbar!

You know there are people in bank and credit institutions that have been doing this for centuries? Probably millennia... EU explicitly requires that some of this is done by what you call AI (i.e. mathematical models) because they are fairer than humans and safer for customers and society

Check basel III for an intro on the topic

Just a small correction because I worked around that area (not for loans but for investment), it's all Algorithms rather than AI.

Algorithms are basically mathematical formulas turned into code, whilst AI is a totally different beast that can produce quite different results on slightly different inputs and it's not really made by turning mathematical models into code but rather it's trained with real world data containing inputs and outputs and "somehow" finds the patterns in that data and can predict the correct outputs if given fresh, never seen before inputs.

AI is probably used for fraud detection (and I expect nowadays it's likely used in algorithmic trading to try and predict market movements) but unless a lot has changed since I was in the business, it's not used for valuations.

It was just to give an idea that what OP mentioned is already an established thing, fairer than alternatives.

Most of the time trivial linear logistic regression is used in this context. Nowadays decision tree ensambles are pretty heavily used, which are ML. Simply they perform better with fewer data than neural networks on structured tabular data.

What you refer to as AI is probably methods based on deep learning. The truth is that they work exactly as any other algorithm that you are referring to. They are used for regression and classification, same way as a standard linear regression. The difference is that the models are non linear, and their complexity is so that a lot of data are needed to train them.

But conceptually one can absolutely create a credit score with deep neural networks. It is just an overkill, for performances that are likely worst than a random forest on relatively small training datasets

Neural networks-based methods are indeed used in fraud detection

Well, I learn something every day!

Cheers!

Ummm… no. Not in tune with that, so interesting to know that I’m not the first! Haha, thanks!

We don't need more discrimination in loan approval. A few years ago, Amazon built an AI that would look at resumes and rate how likely the candidate would be hired. The AI trained itself to recognize female sounding resumes (went to women's only college, is involved in women's organizations, does not use manly enough language) and flag those as undesirables.

Jesus christ that's dystopian

[–] [email protected] 2 points 1 year ago (2 children)

It's not so much dystopian as it is just buggy software

[–] [email protected] 2 points 1 year ago (3 children)

Ah ok. I don't know much about it, but I've heard that AI could sometimes be negative toward commonly discriminated against groups because the data that it's trained with is. (Side note: is that true? someone pls correct me if it's not). I jumped to the conclusion that this was the same thing. My bad

[–] [email protected] 3 points 1 year ago

what it did it expose just how much inherent bias there is in hiring. even just name and gender alone.

[–] [email protected] 3 points 1 year ago

That is both true and pivotal to this story

It's a major hurdle in some uses of AI

[–] [email protected] 1 points 1 year ago

An AI is only as good as its training data. If the data is biased, then the AI will have the same bias. The fact that going to a women's college was considered a negative (and not simply marked down as an education of unknown quality) is proof against the idea that many in the STEM field hold (myself included) that there is a lack of qualified female candidates but not an active bias against them.

When buggy software is used by unreasonably powerful entities to practise (and defend) discrimination that's dystopian...

[–] [email protected] 2 points 1 year ago

Except it wasn't actually launched, and they didn't defend its discrimination but rather ended the project.

We don’t need but we’re going to get!!!!
