Data

The processed data for running the codes could be found in https://www.dropbox.com/sh/w3bh1crt6estijo/AAD9p5m5DceM0z63JOzFV7fxa?dl=0

Dependencies

This set of code was developed in python3 and pytorch. The packages and their respective versions are state in requirements.txt
To install the dependencies, run pip install -r requirements.txt

Training of model

The code for training the model is found in : ./codes
	- The python script that would be used to train the models would be ./train.py
	- Change the config file (./config.py) to change the parameters before training
	- The config file would allow you to change the path of the train, test and val data.
	- The config file would allow you to change the GPUs that would be used for training.
	- Parameters include:
	a. include_key_structure: Boolean, indicating if we should perform structure-aware attention
	b. include_val_structure: Boolean, indicating if we should propagate structure information in the MHA layers
	c. word_module_version: Either 0,1,2,3 or 4, {0: max_pooling, 1: average_pooling, 2: max_pooling_w_attention, 3: average_pooling_w_attention, 4: attention}. The version used in PLAN and STAPLAN is 2, HiT-STAPLAN is 4. 
	d. post_module_version: Either 0,1,2 or 3, {0: average_pooling, 1: condense_into_fix_vector, 2: first_vector, 3: attention}. The version used in all 3 models in the paper is 3. 
	e. vary_LR: Boolean, indicating if we should use increases the LR initially then decreases after a certain point
	f. ff_word: Boolean, indicating if we should finetune the token embedding
	g. ff_post: Boolean, indicating if we should finetune the post embedding
	- To run the training code, run the command "python train.py"

Testing model

The code for testing the model is found in : ./codes
- The ipython notebook that would be used to test the models would be ./testing_script.ipynb
- Change the config file (./config.py) to change the parameters before testing
- The config file would allow you to change the following:
    - The model to select 
        - Models to be selected could be found in ./logs after training
- The path of the testing data
- The path of the output from testing
