Lunar Lander
LunarLanderExperiment
— ModuleLunarLanderExperiment
Experiment module for running experiments in Lunar Lander.
LunarLanderExperiment.main_experiment
— Functionmain_experiment
Run an experiment from config. See LunarLanderExperiment.working_experiment
for details on running on the command line and LunarLanderExperiment.default_config
for info about the default configuration.
LunarLanderExperiment.working_experiment
— Functionworking_experiment
Creates a wrapper experiment where the main experiment is called with progress=true, testing=true and the config is the default_config with the addition of the keyword arguments.
LunarLanderExperiment.default_config
— FunctionAutomatically generated docs for LunarLanderExperiment config.
Experiment details.
seed::Int
: seed of RNGsteps::Int
: Number of steps taken in the experiment
Logging Extras
By default the experiment will log and save (depending on the synopsis flag) the logging group :EXP
. You can add extra logging groups and [group, name] pairs using the below arguments. Everything added to save_extras
will be passed to the save operation, and will be logged automatically. The groups and names added to log_extras
will be ommited from save_results but still passed back to the user through the data dict.
<log_extras::Vector{Union{String, Vector{String}}>
: which group and <name> to log to the data dict. This will not be passed to save.<save_extras::Vector{Union{String, Vector{String}}>
: which groups and <names> to log to the data dict. This will be passed to save.
Environment details
This experiment uses the DirectionalTMaze environment. The usable args are:
size::Int
: Size of the hallway in directional tmaze.
agent details
RNN
The RNN used for this experiment and its total hidden size, as well as a flag to use (or not use) zhu's deep action network. See
cell::String
: The typeof cell. Many types are possible.deepaction::Bool
: Whether to use Zhu et. al.'s deep action 4 RNNs idea. -internal_a::Int
: the size of the action representation layer whendeepaction=true
numhidden::Int
: Size of hidden state in RNNs.
Optimizer details
Flux optimizers are used. See flux documentation and ExpUtils.Flux.get_optimizer
for details.
opt::String
: The name of the optimizer used- Parameters defined by the particular optimizer.
Learning update and replay details including:
Replay:
replay_size::Int
: How many transitions are stored in the replay.warm_up::Int
: How many steps for warm-up (i.e. before learning begins).
Update details:
lupdate::String
: Learning update namegamma::Float
: the discount for learning update.batch_size::Int
: size of batchtruncation::Int
: Length of sequences used for training.update_wait::Int
: Time between updates (counted in agent interactions)target_update_wait::Int
: Time between target network updates (counted in agent interactions)hs_strategy::String
: Strategy for dealing w/ hidden state in buffer.
