garage.np.embeddings.encoder module

Base class for context encoder.

class Encoder[source]

Bases: abc.ABC

Base class of context encoders for training meta-RL algorithms.

input_dim

Dimension of the encoder input.

Type:int
output_dim

Dimension of the encoder output (embedding).

Type:int
reset(do_resets=None)[source]

Reset the encoder.

This is effective only to recurrent encoder. do_resets is effective only to vectoried encoder.

For a vectorized encoder, do_resets is an array of boolean indicating which internal states to be reset. The length of do_resets should be equal to the length of inputs.

Parameters:do_resets (numpy.ndarray) – Bool array indicating which states to be reset.
spec

Input and output space.

Type:garage.InOutSpec
class StochasticEncoder[source]

Bases: garage.np.embeddings.encoder.Encoder

An stochastic context encoders.

An stochastic encoder maps an input to a distribution, but not a deterministic vector.

distribution

Embedding distribution.

Type:object
