Artificial intelligence is poised to reshape therapeutic science. Therapeutics Data Commons is a coordinated initiative to access and evaluate artificial intelligence capability across therapeutic modalities and stages of discovery. It supports the development of AI methods and aims to establish the foundation of which AI methods are most suitable for drug discovery applications and why.
Researchers across disciplines can use TDC for numerous applications. AI-solvable tasks, AI-ready datasets, and curated benchmarks in TDC serve as a meeting point between biochemical and AI scientists. TDC facilitates algorithmic and scientific advances and accelerates machine learning method development, validation, and transition into biomedical and clinical implementation.
TDC is an open-science initiative. We welcome contributions from the community.

TDC has a unique three-tiered hierarchical structure, which to our knowledge, is the first attempt at systematically organizing machine learning for therapeutics. We organize TDC into three distinct problems. For each problem, we provide a collection of learning tasks. Finally, for each task, we provide a series of datasets.
In the first tier, after observing a large set of therapeutics tasks, we categorize and abstract out three major areas (i.e., problems) where machine learning can facilitate scientific advances, namely, single-instance prediction, multi-instance prediction, and generation:
- Single-instance prediction
single_pred: Prediction of property given individual biomedical entity. - Multi-instance prediction
multi_pred: Prediction of property given multiple biomedical entities. - Generation
generation: Generation of new desirable biomedical entities.
The second tier in the TDC structure is organized into learning tasks. Improvement in these tasks can result in numerous applications, including identifying personalized combinatorial therapies, designing novel classes of antibodies, improving disease diagnosis, and finding new cures for emerging diseases.
Finally, in the third tier of TDC, each task is instantiated via multiple datasets. For each dataset, we provide several splits into training, validation, and test sets to simulate the type of understanding and generalization (e.g., the model's ability to generalize to entirely unseen compounds or to granularly resolve patient response to a polytherapy) needed for transition into production and clinical implementation.
TDC provides a collection of workflows with intuitive, high-level APIs for both beginners and experts to create machine learning models in Python. Building off the modularized "Problem -- Learning Task -- Data Set" structure (see above) in TDC, we provide a three-layer API to access any learning task and dataset. This hierarchical API design allows us to easily incorporate new tasks and datasets.
For a concrete example, to obtain the HIA dataset from the ADME therapeutic learning task in the single-instance prediction problem:
from tdc.single_pred import ADME
data = ADME(name = 'HIA_Hou')
# split into train/val/test with scaffold split methods
split = data.get_split(method = 'scaffold')
# get the entire data in the various formats
data.get_data(format = 'df')You can see all the datasets that belong to a task as follows:
from tdc.utils import retrieve_dataset_names
retrieve_dataset_names('ADME')See all therapeutic tasks and datasets on the TDC website!
To retrieve the training/validation/test dataset split, you could type
data = X(name = Y)
data.get_split(seed = 42)
# {'train': df_train, 'val': df_val, 'test': df_test}You can specify the function's splitting method, random seed, and split fractions by, e.g., data.get_split(method = 'scaffold', seed = 1, frac = [0.7, 0.1, 0.2]). Check the data split page for details.
We provide various evaluation metrics for the tasks in TDC, described in model evaluation page on the website. For example, to use metric ROC-AUC, you could type
from tdc import Evaluator
evaluator = Evaluator(name = 'ROC-AUC')
score = evaluator(y_true, y_pred)TDC provides numerous data processing functions, including label transformation, data balancing, pairing data to PyG/DGL graphs, negative sampling, database querying, and so on. For function usage, see our data processing page on the TDC website.
For molecule generation tasks, we provide 10+ oracles for both goal-oriented and distribution learning. For detailed usage of each oracle, please have a look at the oracle page on the website. For example, we want to retrieve the GSK3Beta oracle:
from tdc import Oracle
oracle = Oracle(name = 'GSK3B')
oracle(['CC(C)(C)....'
'C[C@@H]1....',
'CCNC(=O)....',
'C[C@@H]1....'])
# [0.03, 0.02, 0.0, 0.1]Every dataset in TDC is a benchmark, and we provide training/validation and test sets for it, together with data splits and performance evaluation metrics. To participate in the leaderboard for a specific benchmark, follow these steps:
-
Use the TDC benchmark data loader to retrieve the benchmark.
-
Use training and/or validation set to train your model.
-
Use the TDC model evaluator to calculate your model's performance on the test set.
-
Submit the test set performance to a TDC leaderboard.
As many datasets share a therapeutics theme, we organize benchmarks into meaningfully defined groups, which we refer to as benchmark groups. Datasets and tasks within a benchmark group are carefully curated and centered around a theme (for example, TDC contains a benchmark group to support ML predictions of the ADMET properties). While every benchmark group consists of multiple benchmarks, it is possible to separately submit results for each benchmark. Here is the code framework to access the benchmarks:
from tdc import BenchmarkGroup
group = BenchmarkGroup(name = 'ADMET_Group', path = 'data/')
predictions_list = []
for seed in [1, 2, 3, 4, 5]:
benchmark = group.get('Caco2_Wang')
# all benchmark names in a benchmark group are stored in group.dataset_names
predictions = {}
name = benchmark['name']
train_val, test = benchmark['train_val'], benchmark['test']
train, valid = group.get_train_valid_split(benchmark = name, split_type = 'default', seed = seed)
# --------------------------------------------- #
# Train your model using train, valid, test #
# Save test prediction in y_pred_test variable #
# --------------------------------------------- #
predictions[name] = y_pred_test
predictions_list.append(predictions)
results = group.evaluate_many(predictions_list)
# {'caco2_wang': [6.328, 0.101]}For more information, visit here.
