d3rlpy.metrics.scorer.dynamics_prediction_variance_scorer¶
- d3rlpy.metrics.scorer.dynamics_prediction_variance_scorer(dynamics, episodes)[source]¶
Returns prediction variance of ensemble dynamics.
This metrics suggests how dynamics model is confident of test sets. If the variance is large, the dynamics model has large uncertainty.
- Parameters
dynamics (d3rlpy.metrics.scorer.DynamicsProtocol) – dynamics model.
episodes (List[d3rlpy.dataset.Episode]) – list of episodes.
- Returns
variance.
