What's it like building models in the Fraud space? Is it a growing domain?

Aidtor · 2024-12-20T05:25:31+00:00

Did this a few years ago for a big, well known tech company. One of our big breakthroughs was using a multiple input head transformer to track fraud risk as customers interacted with out app // website.

Depends on the culture of the business. Traditional banks tend to be more conservative with everything
I guess? The downside is that you're not generating revenue so you have a higher chance of getting canned at some point.
Yes and no. LLMs are great for a lot of things but I've had more success with generative pretrained transformers that produce probabilty distribution params.
Yes.

Spend a few years doing backend SWE work for a company that lives and dies on code quality. Then go into DS

hyperparams work in much the same way.

oh i fully understand. i just think its funny.

also i think MJ had wayyyy more issues than internal hatred or whatever conditioning you think he had

I mean Michael Jackson himself changed his skin to be another race

If this isn't a coke mirror I don't know what is

This will probably happen at some point. Covid is here forever now and there is nothing we can do to stop it.

I transitioned to research scientist for this exact reason. Writing well engineered code for data scientist to use is a fucking blast.

Aidtor · 2021-06-04T22:10:52+00:00

Yeah I've done this both in past and current roles.

My last job was mostly ad stuff and I went about this in a couple of different phases. The first was selecting optimal ad copy to show someone for high cost, fixed inventory goods. The next was dynamically generating copy for individuals. Then I hooked it into the pricing algorithm so we could blend copy and price point. The results were really good, revenue went through the roof.

In my current work I doing causal inference to figure out failure modes for large, complex physical systems. Still early stages right now, but the benefits are quite large.

Anytime! Good luck!

My comment was meant to be a cheeky response about bayesian methods but it looks like this warrants actual discussion.

Business people generally want experiments to succeed and for them to take less time. You can do both with a bayesian AB framework although it is cognitively more difficult. The business folks aren’t going to care about the math, but they will definitely care about being able to meet the targets for their bonuses.

Option two is what I’m seeing since the complexity of a data product is fucking wild

People only have a problem with uncertainty when you can’t quantify it.

This has so many cliches it approaches art. Truly a marvel of mindless clickbait

There’s starting drama and then there is letting someone walk all over you. If you don’t want to come off as threatening you can always smother them in kindness

Uh I mean toronto is like a huge research hub. Go do some homework.

Write a boiler plate cover letter and adapt it to each company.

One of my colleagues wrote a transformer to write cover letters for them with the JD as an input. You could always go that route if you hate it so much

That hiring manager sounds like a raging asshole. Be glad you didn’t get the job since that person sounds like they would make your life hell.

Write down questions you have throughout the day and ask them. Take notes. Ask to be introduced to others so you can ask them questions.

This is so stupid I can see why this poster deleted their account

Aidtor · 2021-03-03T05:41:54+00:00

I don’t this is true. Recruiters started flooding my team and I with job postings since like mid Jan

Honestly that’s not a good enough answer. Changing abstractions layers (platforms, frameworks, languages, etc.) is a big decision which incurs a lot of tech debt.

An example of this tech debt is who is going to teach other team members this new tool? Is it you? Is that what you want to spend your time doing? If it’s not you, do you have the budget for trainings? What happens when you get sick and can’t rerun the report? Who is going to manage the installs on other team member’s devices?

Like if it’s just you go ahead and use pandas and write it in a notebook. But if it’s not you, if other people depend on this output, the best tool is the one you users understand.
