Great slide deck, thanks!

I am aware of papers where the graph is assumed to be known (e.g. arxiv.org/abs/2103.06392), and indeed I can construct one from the data that I have. But my concern is whether using the empirical graph ignores selection bias from customers choosing to form edges with certain products.

For outcomes, think of long-term customer spend, retail membership signup, or something else that is affected by the customer experience (the aggregate experience from products they interact with) but are not immediate consequences of a single product interaction.

Suppose an A/B test on a retail platform where products are randomly assigned into treatment or control, and outcomes are measured for customers. Edges are customer-product interactions (e.g. viewing a product). The treatment affects the desirability of the product, the likelihood it surfaces, etc.

it’s a weird partition of services: there’s a job board for serious folks and then a feed of cringey wannabe influencers peddling nonsense, phony inspirational stories, and infographics that remind you the difference between a left and right join as if that’s so freaking complicated

does this only work in december or can i put santa in a speedo out in july to signal my interest in having a neighborhood pool party

maybe exposure to the former drove demand for the latter, that’s how it works in my household

love matching my inks to my 3776s, they’re gorgeous pens

not sure how ergo it’d be to hit keys like “e”, seems like an awkward gesture

Slower is better. I left mastodon because it was just people relentlessly boosting the same posts I had already seen. Bluesky is small. We don’t need reposting. If your post was something I wanted to see, I’ll have seen it on one of my feeds already
