### Dataset Summary
**DiTEC-WDN Dataset** consists of 36 Water Distribution Networks (WDNs). Each network has unique 1,000 *scenarios* with distinct characteristics.
*Scenario* represents a timeseries of directed shared-topology *graphs*, referred to as *states* or *snapshots*. In terms of `graph-ml`, it can be seen as a spatiotemporal graph where nodes and edges are multivariate time series. 

A *node* can represent a *reservoir*, *junction*, or *tank*, while an *edge* refers to a *pipe*, *pump*, or *valve*. Notably, this dataset specifies concrete valve types, including *PSV*, *PBV*, *FCV*, *TCV*, and *GPV*. In addition, pump has two distinct types: *head pump* and *power pump*.   
Each component has its own parameters, as listed in the below table:

¹ SIFU stands for SI Flow Units including LPS, LPM, MLD, CMH, and CMD.  
² DW refers to Darcy-Weisbach headloss equation.  

#### Parameter-oriented dataset

For general usage, user may want to download a single parameter of a specific component in a concrete network. This can be done in this example code:
```python
from datasets import load_dataset
raw_dataset = load_dataset(path="rugds/ditec-wdn", data_files="EXN_2GB_24H/junction_elevation*")
```
The downloaded subset is *pressure* values of all *junctions* in network *EXN*. 
User should check out the [file structure](https://huggingface.co/datasets/rugds/ditec-wdn/tree/main) to observe available parameters in each WDN folder.

#### Component-based dataset

For those who download all parameters w.r.t. a generic component type (*node* or *link*), we recommend the list of 72 configs in this `README.md`. 
The naming format is `<network_name>_<storage_size>_<duration>_<general_component>`. 
Please ensure sufficient storage before processing the dataset.
Let's see this example:
```python
from datasets import load_dataset
raw_dataset = load_dataset(path="rugds/ditec-wdn", name="EXN_2GB_24H_node")
```
This will download `parquet` files containing nodal features of the network *EXN*. 
Note that this action merges all parameters regardless of their type, so user should pay attention to the shape.

#### PyTorch(PyG) dataset

We also support a data interface to provide a parameter-mergable and ready-to-use dataset for PyTorch users. 
The interface and examples can be found in our official [GitHub](https://github.com/DiTEC-project/DiTEC_WDN_dataset). 

#### Miscellaneous information
All metadata, such as profiler info, simulation and optimization configurations, and network topology, is included in every Parquet file for a given WDN.
To access it, user should retrieve a target WDN folder, pick a (light-weight) parquet file, and read its metadata using *pyarrow* libary.
We provide a snippet supporting this as follows:
```python
import tempfile
from huggingface_hub import hf_hub_download
import pyarrow.parquet as pq
def get_metadata(parquet_path: str, path: str = "rugds/ditec-wdn", key: str = "attrs") -> dict:
    with tempfile.TemporaryDirectory(dir="data", ignore_cleanup_errors=True) as dirpath:
        parquet_path = hf_hub_download(repo_id=path, repo_type="dataset", filename=parquet_path, local_dir=dirpath)
        metadata = pq.read_metadata(parquet_path)
        binary_meta_dict = metadata.metadata
        bkey = key.encode()
        if bkey in binary_meta_dict:
            attrs = binary_meta_dict[bkey].decode()
            return attrs
        else:
            print("Error! Key not found!")
            return {}
```


### Supported Tasks and Leaderboards

* `graph-ml`: The dataset can be used to train a model for graph-related tasks, including node-level, link-level, and graph-level regressions.  
* `time-series-forecasting`: The dataset can be used to train a model for time series forecasting tasks, including multivariate state estimation and next state forecasting.

Success on both tasks is typically measured by achieving:\
(1) low Mean Absolute Error (MAE)\
(2) low Mean Absolute Percentage Error (MAPE)\
(3) low (Root) Mean Squared Error (RMSE/MSE)\
(4) high coefficient of determination (R**2)\
(5) high Nash–Sutcliffe Efficiency (NSE)

## Dataset Creation
### Curation Rationale
The dataset is designed to (1) encourage open scientific research in the fundamental field of water, (2) eliminate the risk of exposing sensitive data while addressing strict privacy concerns that hinder advancements in machine learning, and (3) fulfill the need for a large-scale water distribution network benchmark for study comparisons and scenario analysis.
### Source Data
The source data consists of simulation metadata files (.INP) collected from public resources. However, we retain only topology and component names, discarding all hydraulic-related values (e.g., elevation, demand time series, diameter, etc). These discarded values are later re-synthesized by our generator. As a result, the dataset contains no real or sensitive information from the original metadata or real-world systems.

Their INPs are available [here](https://github.com/DiTEC-project/DiTEC_WDN_dataset/tree/main/ditec_wdn_dataset/inputs/public).
Please note that the files were employed exclusively for optimization, not included in the dataset, as each scenario corresponds to a distinct INP file theoretically.

#### Who are the source language producers?
The dataset was machine-generated. The process detail could be found in the co-existence paper (see [Citation Information](#citation-information)).
