# Binding Affinity Dataset |
|
|
|
|
|
## Overview |
|
|
|
|
|
This dataset is a comprehensive collection of protein-ligand binding affinity data, compiled from multiple sources. The dataset is structured with multiple splits, each corresponding to a specific source: |
|
|
|
|
|
- train split (glaser.parquet) |
|
|
- val split (pdbbind-2013-core.parquet) |
|
|
- davis split |
|
|
- davis_filtered split |
|
|
- kiba split |
|
|
- pdbbind_2020_general split |
|
|
- pdbbind_2020_refined split |
|
|
- pdbbind_2013_core split |
|
|
- bindingdb_ic50 split |
|
|
- bindingdb_ki split |
|
|
- bindingdb_kd_filtered split |
|
|
- bindingdb_kd split |
|
|
- glaser split |
|
|
|
|
|
## Training Dataset Composition |
|
|
|
|
|
The training split uses the Glaser dataset, while the validation split uses the PDBBind 2013 Core dataset. |
