multi-armed bandit

← all terms

Definition

Plain language

A classic decision puzzle about when to keep using what already works versus trying something new that might be better.

As stated in the literature

A reinforcement-learning framework formalizing the explore-exploit tradeoff over actions with unknown payoffs; LoopTrap's strategy selection uses bandit-style exploration weighted by behavioral priors.

Also called: bandit

Why it matters: It captures the universal explore-versus-exploit tradeoff, guiding systems that must balance using what works against discovering something better.

For example, it's like deciding each night whether to revisit your favorite restaurant or try a new one that might be even better.

Heard on the show

“The strategy selection underneath is exploration-exploitation, the multi-armed bandit kind of logic.”
