TRPO-GAE (Version 0) Writeup

Code used to obtain these results can be found at the url https://github.com/joschu/modular_rl, commit 50cdfdf375e69d86e3db6eb2ad0218ea6aebf371. The command line expression used for all the environments can be found in the text file below. Note that the same exact parameters and policies were used for all tasks, except for timesteps_per_batch, which was varied based on the difficulty of the task. The important parameters are:

  • gamma=0.995: discount
  • lam=0.97: see GAE paper for explanation
  • agent=TrpoAgent: name of the class, which specifies policy and value function architecture. In this case, we used two hidden layers of size 64, with tanh activations
  • cg_damping: multiple of the identity added for conjugate gradient

Super simple python script that uses boto to connect to amazon mturk. If you use the sandbox, you'll see a balance of $10,000! Otherwise, you'll see your normal balance.
import boto.mturk.connection
sandbox_host = 'mechanicalturk.sandbox.amazonaws.com'
real_host = 'mechanicalturk.amazonaws.com'
mturk = boto.mturk.connection.MTurkConnection(
aws_access_key_id = 'XXX',
aws_secret_access_key = 'XXX',
host = sandbox_host,
debug = 1 # debug = 2 prints out all requests. but we'll just keep it at 1

git utility to move/rename file or folder and retain history with it.
#!/bin/bash
#
# git-mv-with-history -- move/rename file or folder, with history.
#
# Moving a file in git doesn't track history, so the purpose of this
# utility is best explained from the kernel wiki:
#
# Git has a rename command git mv, but that is just for convenience.
# The effect is indistinguishable from removing the file and adding another
# with different name and the same content.
