Translating Navigation Instructions in Natural Language to a High-Level Plan for Behavioral Robot Navigation

* equal contribution.

Setup

Run the following command to install dependencies and libraries, download glove embeddings and dataset for experiments.

sh get_started.sh

Usage

Training

python codes/main.py --experiment_name=[unique name for model folder] --data_dir data

You can also download the Trained model

Test

Evaluate the F1 score and Exact Match on the dev/test dataset, which can be decided by --file_in_path.

python codes/main.py --train_dir=experiments/[experiment name] --mode=official_eval --data_dir data --file_in_path [dev/test]

--file_out_path is needed if you want to write the prediction out to a file. [--write_out=True]

Run the following instruction to evaluate the result and plot the error analysis.

python codes/evaluate.py ground_truth_file prediction_file

Show examples

Show the predictions of some examples. --file_in_path decides the dataset to test with. There are three valid arguments: dev, test, test_diff_maps, which respectively mean validation set, test-repeated map set, test-new map set.

python codes/main.py --train_dir=experiments/[experiment name] --mode=show_examples --data_dir data --file_in_path [dev/test/test_diff_maps] --print_num 10

Examples

Example training commmand:

python codes/main.py --experiment_name=my_experiment --mode=train --data_dir my_data

Example test command:

python codes/main.py --train_dir experiments/my_experiment --mode=official_eval --data_dir my_data
