# Overview
Cardea is a machine learning library built on top of *schemas* that support electronic health records (EHR). The library uses a number of AutoML tools developed under [The Human Data Interaction Project](https://github.com/HDI-Project) at [Data to AI Lab at MIT](https://dai.lids.mit.edu/).
Our goal is to provide an easy to use library to develop machine learning models from electronic health records. A typical usage of this library will involve interacting with our API to develop prediction models.
A series of sequential processes are applied to build a machine learning model. These processes are triggered using our following APIs to perform the following:
* loading data using the automatic **data assembler**, where we capture data from its raw format into an entityset representation.
* **data labeling** where we create label times that generates (1) the time index that indicates the timespan for which I create my features (2) the encoded labels of the prediction task. this is essential for our feature engineering phase.
* **featurization** for which we automatically feature engineer our data to generate a feature matrix.
* lastly, we build, train, and tune our machine learning model using the **modeling** component.
to learn more about how we structure our machine learning process and our data structures, read our documentation [here](https://MLBazaar.github.io/Cardea).
# Quickstart
## Install with pip
The easiest and recommended way to install **Cardea** is using [pip](https://pip.pypa.io/en/stable/):
```bash
pip install cardea
```
This will pull and install the latest stable release from [PyPi](https://pypi.org/).
## Quickstart
In this short tutorial we will guide you through a series of steps that will help you get Cardea started.
First, load the core class to work with:
```python3
from cardea import Cardea
cardea = Cardea()
```
We then seamlessly plug in our data. Here in this example, we are loading a pre-processed version of the [Kaggle dataset: Medical Appointment No Shows](https://www.kaggle.com/joniarroba/noshowappointments).
To use this dataset download the data from here then unzip it in the root directory, or run the command:
```bash
curl -O https://dai-cardea.s3.amazonaws.com/kaggle.zip && unzip -d kaggle kaggle.zip
```
To load the data, supply the ``data`` to the loader using the following command:
```python3
cardea.load_entityset(data='kaggle')
```
> :bulb: To load local data, pass the folder path to ``data``.
To verify that the data has been loaded, you can find the loaded entityset by viewing ``cardea.es`` which should output the following:
```bash
Entityset: kaggle
Entities:
Address [Rows: 81, Columns: 2]
Appointment_Participant [Rows: 6100, Columns: 2]
Appointment [Rows: 110527, Columns: 5]
CodeableConcept [Rows: 4, Columns: 2]
Coding [Rows: 3, Columns: 2]
Identifier [Rows: 227151, Columns: 1]
Observation [Rows: 110527, Columns: 3]
Patient [Rows: 6100, Columns: 4]
Reference [Rows: 6100, Columns: 1]
Relationships:
Appointment_Participant.actor -> Reference.identifier
Appointment.participant -> Appointment_Participant.object_id
CodeableConcept.coding -> Coding.object_id
Observation.code -> CodeableConcept.object_id
Observation.subject -> Reference.identifier
Patient.address -> Address.object_id
```
The output shown represents the entityset data structure where ``cardea.es`` is composed of entities and relationships. You can read more about entitysets [here](https://mlbazaar.github.io/Cardea/basic_concepts/data_loading.html).
From there, you can select the prediction problem you aim to solve by specifying the name of the class, which in return gives us the ``label_times`` of the problem.
```python3
label_times = cardea.select_problem('MissedAppointment')
```
``label_times`` summarizes for each instance in the dataset (1) what is its corresponding label of the instance and (2) what is the time index that indicates the timespan allowed for calculating features that pertain to each instance in the dataset.
```bash
cutoff_time instance_id label
0 2015-11-10 07:13:56 5030230 noshow
1 2015-12-03 08:17:28 5122866 fulfilled
2 2015-12-07 10:40:59 5134197 fulfilled
3 2015-12-07 10:42:42 5134220 noshow
4 2015-12-07 10:43:01 5134223 noshow
```
You can read more about ``label_times`` [here](https://mlbazaar.github.io/Cardea/basic_concepts/machine_learning_tasks.html).
Then, you can perform the AutoML steps and take advantage of Cardea.
Cardea extracts features through automated feature engineering by supplying the ``label_times`` pertaining to the problem you aim to solve
```python3
feature_matrix = cardea.generate_features(label_times[:1000])
```
> :warning: Featurizing the data might take a while depending on the size of the data. For demonstration, we only featurize the first 1000 records.
Once we have the features, we can now split the data into training and testing
```python3
y = list(feature_matrix.pop('label'))
X = feature_matrix.values
X_train, X_test, y_train, y_test = cardea.train_test_split(
X, y, test_size=0.2, shuffle=True)
```
Now that we have our feature matrix properly divided, we can use to train our machine learning pipeline, Modeling, optimizing hyperparameters and finding the most optimal model
```python3
cardea.select_pipeline('Random Forest')
cardea.fit(X_train, y_train)
y_pred = cardea.predict(X_test)
```
Finally, you can evaluate the performance of the model
```python3
cardea.evaluate(X, y, test_size=0.2, shuffle=True)
```
which returns the scoring metric depending on the type of problem
```bash
{'Accuracy': 0.75,
'F1 Macro': 0.5098039215686274,
'Precision': 0.5183001719479243,
'Recall': 0.5123528436411872}
```
