Streaming Deep Reinforcement Learning

Streaming Deep RL (wip)

Explorations into the proposed Streaming Deep Reinforcement Learning, from University of Alberta.

Once completed, if it checks out, will reach to integrate the Stream Q(λ) with Q-Transformer.

A recent testimony to Streaming AC(λ) variant can be found here. Will be incorporated into the repository as well with a few improvements.

Paper reading by Youtube AI/ML educator @hu-po.

The official repository can be found here.

Install

$ pip install streaming-deep-rl

Usage

import torch

from streaming_deep_rl import StreamingACLambda
from x_mlps_pytorch.normed_mlp import MLP

# actor and critic

actor = MLP(
    8, 128, 128, 128,
    norm_elementwise_affine = False,
    activate_last = True
)

critic = MLP(
    8, 128, 128, 1,
    norm_elementwise_affine = False
)

# agent

agent = StreamingACLambda(
    actor = actor,
    critic = critic,
    dim_state = 8,
    dim_actor = 128,
    num_discrete_actions = 4
)

# get action distr

state = torch.randn(8)
action_dist = agent(state)

# sample action

action = agent.sample_action(action_dist)

# environment gives back

next_state = torch.randn(8)
reward = torch.tensor(1.)
done = torch.tensor(False)

# update at each timestep, "streaming"

agent.update(
    state = state,
    action = action,
    next_state = next_state,
    reward = reward,
    is_terminal = done
)
