Description:

The Maja Machine Learning Framework (MMLF) is a general framework for problems in the domain of Reinforcement Learning (RL) written in python. It provides a set of RL related algorithms and a set of benchmark domains. Furthermore it is easily extensible and allows to automate benchmarking of different agents. Among the RL algorithms are TD(lambda), CMA-ES, EANT, Fitted R-Max, and Monte-Carlo learning. MMLF contains different variants of the maze-world and pole-balancing problem class as well as the mountain-car testbed.

Changes to previous version:
  • Monitor can now also be configured in MMLF Explorer
  • MMLF Experimenter can now also load results of a prior experiment
  • MMLF Experimenter allows to specify whether world runs should be conducted sequentially or concurrently
  • Added simple LinearMarkovChain environment
  • Added "Writing an experiment" tutorial
  • Removed EANT and CGE from MMLF

0.9.9
  • Configuration files for worlds (i.e. for agents and environments) are now in the yaml syntax (and no longer in xml)
  • MMLF GUI can now load and store world configuration files
  • Experiments in the MMLF Experimenter can now consist of arbitrary many worlds (and not just two agents in the same world)
  • MMLF Experimenter supports now parallel execution of experiments (each world in a separate process). This is based on the multiprocessing framework.
  • Logging to files and providing information for the GUI is now handled both using Observables. This reduces code duplication.
  • Added Actor-Critic agent
  • Added Pinball Maze environment
  • Added Discrete BRIO Labyrinth environment
  • Added model for discrete environments which stores the transition probabilities for each (state, action, successor state) in a dict entry
  • Added planner interface and refactored dynamic programming, prioritized sweeping etc. such that they implement this interface
  • Added several viewers (both environment-specific as well as general purpose viewers for trajectories, value functions, policies etc.)

0.9.8
  • Added "Experimenter" GUI to MMLF that allows to compare the performance of different agents
  • Various small improvements of the GUI
  • Added a simple two-player card game environment called "Seventeen and Four"
June 4, 2010, 11:39:55
0.9.7

Added model-based learning algorithms DYNA-TD and model-based direct policy search (MBDPS). Added an initial version of a graphical user interface
