DictProbabilityDistribution

class maze.distributions.dict.DictProbabilityDistribution(distribution_dict: Dict[str, maze.distributions.distribution.ProbabilityDistribution])

Dictionary probability distribution.

The respective functions either return

• the per key distribution properties or

• aggregate the properties across the sub-distributions using a reduce_fun such as mean or sum.

Parameters

distribution_dict – dictionary holding sub-probability distributions.

deterministic_sample() → Dict[str, torch.Tensor]

entropy(reduce_fun: callable = torch.mean) → torch.Tensor
