Hey there,
I believe you want a custom task. In DSO, a Task
is largely defined by a search space and a reward function. Both can be arbitrarily/custom designed. For symbolic regression (regression
task), the search space is the space of mathematical expressions, and the reward function is fitness of that expression to a dataset. For the control
task, the search space is the same, but the reward function is how well that expression performs when instantiated as a policy in an RL environment.
It sounds like you want to define another Task
with that same search space (expressions) but a different reward function.
Can't say much else without knowing more, but take a look at the custom example we have and how to configure it. Basically, you'll want to (1) mimic part of the regression
/control
task (namely, inherit from dso.task.HierarchicalTask
and have a dso.library.Library
consisting of mathematical operators... the combination of these two essentially gives you the expression search space), then (2) implement reward_function()
however you want.
Thanks,
