Possibly unexpected behaviour of decision function about contextualbandits

[david-cortes]

Key there is the parameter beta_prior. If you don't want any randomization in a call to predict, you can pass parameter exploit=True. However, the whole point of BootstrappedTS is to use that randomization in making choices. If you want reproducible results across multiple calls on the same data, you can also try resetting the random number generators before each call (this is not documented and not part of the public attributes so you'll have to look into the source code).
