|
|
|
### Dataset Summary |
|
|
|
The `ZINC` dataset is a "curated collection of commercially available chemical compounds prepared especially for virtual screening" (Wikipedia). |
|
|
|
### Supported Tasks and Leaderboards |
|
|
|
`ZINC` should be used for molecular property prediction (aiming to predict the constrained solubility of the molecules), a graph regression task. The score used is the MAE. |
|
|
|
The associated leaderboard is here: [Papers with code leaderboard](https://paperswithcode.com/sota/graph-regression-on-zinc). |
|
|
|
## External Use |
|
### PyGeometric |
|
To load in PyGeometric, do the following: |
|
|
|
```python |
|
from datasets import load_dataset |
|
|
|
from torch_geometric.data import Data |
|
from torch_geometric.loader import DataLoader |
|
|
|
dataset_hf = load_dataset("graphs-datasets/<mydataset>") |
|
# For the train set (replace by valid or test as needed) |
|
dataset_pg_list = [Data(graph) for graph in dataset_hf["train"]] |
|
dataset_pg = DataLoader(dataset_pg_list) |
|
|
|
``` |
|
|
|
|
|
## Dataset Structure |
|
|
|
### Data Properties |
|
|
|
| property | value | |
|
|---|---| |
|
| scale | big | |
|
| #graphs | 220011 | |
|
| average #nodes | 23.15 | |
|
| average #edges | 49.81 | |
|
|
|
### Data Fields |
|
|
|
Each row of a given file is a graph, with: |
|
- `node_feat` (list: #nodes x #node-features): nodes |
|
- `edge_index` (list: 2 x #edges): pairs of nodes constituting edges |
|
- `edge_attr` (list: #edges x #edge-features): for the aforementioned edges, contains their features |
|
- `y` (list: 1 x #labels): contains the number of labels available to predict (here 1, equal to zero or one) |
|
- `num_nodes` (int): number of nodes of the graph |
|
|
|
### Data Splits |
|
|
|
This data comes from the PyGeometric version of the dataset, and follows the provided data splits. |
|
This information can be found back using |
|
```python |
|
from torch_geometric.datasets import ZINC |
|
|
|
dataset = ZINC(root = '', split='train') # valid, test |
|
``` |
|
|
|
