In our new paper https://t.co/uwAtDIaJwu , @skdeshpande91 and I develop a framework for estimating the optimal swing decision of batters in Major League Baseball. We take a Bayesian approach to estimating the expected runs following a swing and take decision. (5/7)

Giving a talk at JSM tomorrow on ridgeBART!

This is a game-changer for sports analytics. Our method opens up new possibilities for modeling complex spatial data on large datasets, allowing us to tackle problems that simply weren't possible before with tree-based models.

[Ryan Yee @ryanyee98]

I'll be discussing the details of the method and demonstrating its capabilities on an NBA shot dataset.

As a preview, here is a comparison of FG% estimates by BART and ridgeBART for Stephen Curry:

Two thoughts: i) the way you use the tool matters, creativity and ingenuity continue to be rewarded; ii) demand for inference-time compute will continue to grow exponentially https://t.co/0NiMsbeeHY

@matteopelleg Not impressed. It’s very easy to predict crime in Chicago. Just predict yes and you should be right 99% of the time

I was talking to someone who works in real estate this weekend. He said discount rates on commercial properties are typically 10-20% but currently closer to 20-30%. Meanwhile, discount rates on residential are <10%, with a point estimate around 5%. Seems like a big opportunity.

Using our framework, teams can identify batters who consistently make optimal swing decisions and identify situations and pitch locations where specific batters tend to make sub-optimal decisions. These analyses can be conducted using our shiny app: https://t.co/p41l7G10md (7/7)

The notion of plate discipline in baseball refers to the idea that batters should be selective in the pitches they choose to swing at. Given this principle, the question arises: how should batters determine which pitches are worth a swing? (1/7)

[Ryan Yee @ryanyee98]

Our analysis finds that, indeed, there are other factors other than location that have an effect on the optimal swing decision. (6/7)
