🌀 What is it?
-----

The **unravelsports** package aims to aid researchers, analysts and enthusiasts by providing intermediary steps in the complex process of converting raw sports data into meaningful information and actionable insights.

This package currently supports:
- ⚽ 🏈 [**Polars DataFrame Conversion**](#polars-dataframes) 
- ⚽ 🏈 [**Graph Neural Network**](#graph-neural-networks) Training, Graph Conversion and Prediction <small>
  [[Bekkers & Sahasrabudhe (2023)](https://arxiv.org/pdf/2411.17450)]</small>
- ⚽ [**Pressing Intensity**](#pressing-intensity) 
  <small>[[Bekkers (2024)](https://arxiv.org/pdf/2501.04712)]</small>

🌀 Features
-----

### **Polars DataFrames**

⚽🏈 **Convert Tracking Data** into [Polars DataFrames](https://pola.rs/) for rapid data conversion and data processing. 

⚽ For soccer we rely on [Kloppy](https://kloppy.pysport.org/) and as such we support _Sportec_$^1$, _SkillCorner_$^1$, _PFF_$^{1, 2}$, _Metrica_$^1$, _StatsPerform_, _Tracab (CyronHego)_ and _SecondSpectrum_ tracking data.
```python
from unravel.soccer import KloppyPolarsDataset

from kloppy import sportec

kloppy_dataset = sportec.load_open_tracking_data()
kloppy_polars_dataset = KloppyPolarsDataset(
    kloppy_dataset=kloppy_dataset
)
```

$^1$ <small>Open data available through kloppy.</small>

$^2$ <small>Currently unreleased in kloppy, only available through kloppy master branch. [Click here for World Cup 2022 Dataset](https://www.blog.fc.pff.com/blog/enhanced-2022-world-cup-dataset)</small> 

🏈 For American Football we use [BigDataBowl Data](https://www.kaggle.com/competitions/nfl-big-data-bowl-2025/data) directly.

```python
from unravel.american_football import BigDataBowlDataset

bdb = BigDataBowlDataset(
    tracking_file_path="week1.csv",
    players_file_path="players.csv",
    plays_file_path="plays.csv",
)
```

### **Graph Neural Networks**

⚽🏈 Convert **[Polars Dataframes](#polars-dataframes)** into [Graphs](examples/graphs_faq.md) to train **graph neural networks**. These [Graphs](examples/graphs_faq.md) can be used with [**Spektral**](https://github.com/danielegrattarola/spektral) - a flexible framework for training graph neural networks. 
`unravelsports` allows you to **randomize** and **split** data into train, test and validation sets along matches, sequences or possessions to avoid leakage and improve model quality. And finally, **train**, **validate** and **test** your (custom) Graph model(s) and easily **predict** on new data.

```python
from unravel.soccer import SoccerGraphConverter

converter = SoccerGraphConverter(
    dataset=kloppy_polars_dataset,
    self_loop_ball=True,
    adjacency_matrix_connect_type="ball",
    adjacency_matrix_type="split_by_team",
    label_type="binary",
    defending_team_node_value=0.1,
    non_potential_receiver_node_value=0.1,
    random_seed=False,
    pad=False,
    verbose=False,
)
```

### **Pressing Intensity**

Compute [**Pressing Intensity**](https://arxiv.org/abs/2501.04712) for a whole game (or segment) of Soccer tracking data.

See [**Pressing Intensity Jupyter Notebook**](examples/pressing_intensity.ipynb) for an example how to create mp4 videos.

```python
from unravel.soccer import PressingIntensity

import polars as pl

model = PressingIntensity(
    dataset=kloppy_polars_dataset
)
model.fit(
    start_time = pl.duration(minutes=1, seconds=53),
    end_time = pl.duration(minutes=2, seconds=32),
    period_id = 1,
    method="teams",
    ball_method="max",
    orient="home_away",
    speed_threshold=2.0,
) 
```

🌀 Installation
----
The easiest way to get started is:

```bash
pip install unravelsports

tensorflow==2.14.0 
keras==2.14.0
kloppy==3.17.0
polars==1.2.1
```
These dependencies come pre-installed with the package. It is advised to create a [virtual environment](https://virtualenv.pypa.io/en/latest/).

This package is tested on the latest versions of Ubuntu, MacOS and Windows.
