What does it take to build an AI model that can accurately simulate human behavior?

You need to understand both what people do and why they do it.

On Sept 24, @msbernst is taking us under the hood of behavioral simulation. We’ll explore why neither behavioral data nor surveys and interviews are enough on their own, what each reveals about human behavior, and how Simile brings them together to model what people might do next.

I describe AI behavioral simulation as a “what-if” machine. I wrote about what a What-If Machine is, and how it works, at @simile_ai:
Simile @simile_ai Sep 2
Most big decisions are some version of a “what-if” question.

What if we launched this? What if we raised the price? What if we didn’t?

At Simile, we’re building a What-If Machine to simulate those decisions before making them for real. But getting the answer right requires understanding both what people do and why they do it.

@msbernst explains what it takes to build one.

Behavioral simulation requires confidence estimation. I'm 100% fine asking the system to simulate unlikely situations if it can signal lower confidence, so long as I can also get high confidence simulations and calibrate my trust.

Simile trains a simulation model. Also, we train another model that predicts the error of the simulation model (the “confidence model”). Tucked away in a secret dungeon below Mission Bay, we also have a “confidence confidence model” that predicts the error of the confidence model, but this one is saddled with a certain sinister statistical spirit that must be contained at all costs! To contain San Francisco’s crisis of confidence, Members of Technical Staff across the valley must come together and read Simile’s confidence blog post today!
