Requirements

Python 3.7+
PyTorch 1.10+
Cuda 10.2+ (If you plan to use GPU)

Note:

Most models can be run quickly on CPU.
You are required to have a GPU with 12GB memory to run ConCare model on CDSL dataset.
TCN model may run much faster on CPU.

Usage

Install requirements.

pip install -r requirements.txt [-i https://pypi.tuna.tsinghua.edu.cn/simple] # [xxx] is optional

Download TJH dataset from An interpretable mortality prediction model for COVID-19 patients, unzip and put it in datasets/tongji/raw_data/ folder.
Run preprocessing notebook. (You can skip this step if you have already done this in the later training process)
(The CDSL dataset is also the same process.) You need to apply for the CDSL dataset if necessary. Covid Data Save Lives Dataset

Run following commands to train models.

python main.py --cfg configs/xxx.yaml [--train] [--cuda CUDA_NUM] [--db]
# Note:
# 1) use --train for training, only infererence stage if not
# 2) If you plan to use CUDA, use --cuda 0/1/2/...
# 3) If you have configured database settings, you can use --db to upload performance after training to the database.

Data Format

The shape and meaning of the tensor fed to the models are as follows:

x.pkl: (N, T, D) tensor, where N is the number of patients, T is the number of time steps, and D is the number of features. At $D$ dimention, the first $x$ features are demographic features, the next $y$ features are lab test features, where $x + y = D$
y.pkl: (N, T, 2) tensor, where the 2 values are [outcome, length-of-stay] for each time step.
visits_length.pkl: (N, ) tensor, where the value is the number of visits for each patient.
missing_mask.pkl: same shape as x.pkl, tell whether features are imputed. 1: existing, 0: missing.

Pre-processed data are stored in datasets/{dataset}/processed_data/ folder.

Database preparation [Optional]

Example db.yaml settings, put it in configs/_base_/db.yaml.

engine: postgresql # or mysql
username: db_user
password: db_password
host: xx.xxx.com
port: 5432
database: db_name

Create perflog table in your database:

-- postgresql example
create table perflog
(
	id serial
		constraint perflog_pk
			primary key,
	record_time integer,
	model_name text,
	performance text,
	hidden_dim integer,
	dataset text,
	model_type text,
	config text,
	task text
);

-- mysql example
create table perflog
(
	id int auto_increment,
	record_time int null,
	model_name text null,
	task text null,
	performance text null,
	hidden_dim int null,
	dataset text null,
	model_type text null,
	config text null,
	constraint perflog_id_uindex
		unique (id)
);

alter table perflog
	add primary key (id);
