This repository contains:

• curriculum algorithms (in auto_curri), i.e.:
  • the ones introduced in the "Teacher-Student Curriculum Learning" paper
  • the ones introduced in the "Mastering Rate based Curriculum Learning" paper
• curriculums (in curriculums), i.e.:
  • 3 SL curriculums: Addition3, Addition5, Addition9
  • 3 RL curriculums: BlockedUnlockPickup, KeyCorridor, ObstructedMaze
• scripts (in scripts) to easily:
  • train a model, using the curriculms and curriculum algorithms of the repository
  • evaluate it
  • visualize it (for RL only)

1. Clone this repository.
2. Execute: pip install requirements.txt

Curriculums are represented by directed acyclic graphs on tasks. For every task are given estimations of the minimum and maximum possible performances on them. They are useful for the mastering rate based curriculum algorithms.

This repository contains 3 versions of the Addition curriculum: Addition3, Addition5 and Addition9.

The Addition9 curriculum consists in learning how to sum two 9-digits numbers by first learning to sum two 1-digit number, then two 2-digits numbers, etc...

Addition3 and Addition5 curriculums are weaker versions of it, for respectively learning to sum two 3-digits numbers and two 5-digits numbers.

This repository contains:

• BlockedUnlockPickup: description and pictures.
• KeyCorridor: description and pictures.
• ObstructedMaze: description and pictures.

Two scripts (for SL and RL settings) are available for training a model, either on a task or on a curriculum of tasks.

For SL:

A command for training on the Addition4 data generator:

python -m scripts.train_sl --gen Addition4

A command for training on the Addition3 curriculum with the default curriculum algorithm and setting model's name to Addition3:

python -m scripts.train_sl --curriculum Addition3  --model Addition3

A lot of arguments are available to select the good curriculum algorithm, learning rate, etc...

For RL:

A command for training on the MiniGrid Unlock environment:

python -m scripts.train_sl --env MiniGrid-Unlock-v0

A command for training on the BlockedUnclockPickup curriculum with the default curriculum algorithm and setting model's name to BlockedUnlockPickup:

python -m scripts.train_rl --curriculum BlockedUnlockPickup --model BlockedUnlockPickup

Again, a lot of arguments are available to choose the correct default curriculum algorithm, learning rate, etc...

Visualization

For visualizing the training progress of a particular model, execute the following command:

tensorboard --logdir=storage/models/BlockedUnlockPickup

Two scripts (for SL and RL settings) are available for evaluating a model on a task.

For SL:

A command for evaluating the Addition3 model on the Addition3 task on 100 examples:

python -m scripts.evaluate_sl --gen Addition3 --model Addition3

For RL:

A command for evaluating the BlockedUnlockPickup model on the BlockedUnlockPickup task during 100 episodes:

python -m scripts.evaluate_rl --env MiniGrid-BlockedUnlockPickup-v0 --model BlockedUnlockPickup

A script for visualizing how the learner behaves is avaibable in the RL setting:

python -m scripts.visualize_rl --env MiniGrid-BlockedUnlockPickup-v0 --model BlockedUnlockPickup
