Diverse Genomic Embedding Benchmark

Installation | Usage | Leaderboard | Citing

DGEB is a benchmark for evaluating biological sequence models on functional and evolutionary information.

DGEB is designed to evaluate model embeddings using:

• Diverse sequences accross the tree of life.
• Diverse tasks that capture different aspects of biological function.
• Both amino acid and nucleotide sequences.

The current version of DGEB consists of 18 datasets covering all three domains of life (Bacteria, Archaea and Eukarya). DGEB evaluates embeddings using six different embedding tasks: Classification, BiGene mining, Evolutionary Distance Similarity (EDS), Pair Classification, Clustering, and Retrieval.

We welcome contributions of new tasks and datasets.

Installation

Install DGEB using pip.

pip install dgeb

Usage

• Launch evaluation using the python script (see cli.py):

dgeb --model facebook/esm2_t6_8M_UR50D

• To see all supported models and tasks:

dgeb --help

• Using the python API:

import dgeb

model = dgeb.get_model("facebook/esm2_t6_8M_UR50D")
tasks = dgeb.get_tasks_by_modality(dgeb.Modality.PROTEIN)
evaluation = dgeb.DGEB(tasks=tasks)
evaluation.run(model, output_folder="results")

Using a custom model

Custom models should be wrapped with the dgeb.models.BioSeqTransformer abstract class, and specify the modality, number of layers, and embedding dimension. See models.py for additional examples on custom model loading and inference.

import dgeb
from dgeb.models import BioSeqTransformer
from dgeb.tasks.tasks import Modality

class MyModel(BioSeqTransformer):

    @property
    def modality(self) -> Modality:
        return Modality.PROTEIN

    @property
    def num_layers(self) -> int:
        return self.config.num_hidden_layers

    @property
    def embed_dim(self) -> int:
        return self.config.hidden_size


model = MyModel(model_name='path_to/huggingface_model')
tasks = dgeb.get_tasks_by_modality(model.modality)
evaluation = dgeb.DGEB(tasks=tasks)
evaluation.run(model)

Evaluating on a custom dataset

We strongly encourage users to contribute their custom datasets to DGEB. Please open a PR adding your dataset so that the community can benefit!

To evaluate on a custom dataset, first upload your dataset to the Huggingface Hub. Then define a Task subclass with TaskMetadata that points to your huggingface dataset. For example, a classification task on a custom dataset can be defined as follows:

import dgeb
from dgeb.models import BioSeqTransformer
from dgeb.tasks import Dataset, Task, TaskMetadata, TaskResult
from dgeb.tasks.classification_tasks import run_classification_task

class MyCustomTask(Task):
    metadata = TaskMetadata(
        id="my_custom_classification",
        display_name="...",
        description="...",
        type="classification",
        modality=Modality.PROTEIN,
        datasets=[
            Dataset(
                path="path_to/huggingface_dataset",
                revision="...",
            )
        ],
        primary_metric_id="f1",
    )

    def run(self, model: BioSeqTransformer) -> TaskResult:
        return run_classification_task(model, self.metadata)

model = dgeb.get_model("facebook/esm2_t6_8M_UR50D")
evaluation = dgeb.DGEB(tasks=[MyCustomTask])
evaluation.run(model)

Leaderboard

To add your submission to the DGEB leaderboard, proceed through the following instructions.

1. Fork the DGEB repository by following GitHub's instruction Forking Workflow.

2. Add your submission .json file to the leaderboard/submissions/<HF_MODEL_NAME>/ directory.

mv /path/to/<SUBMISSION_FILE>.json /path/to/DGEB/leaderboard/submissions/<HF_MODEL_NAME>/

4. Update your fork with the new submission:

git add leaderboard/submissions/<HF_MODEL_NAME>/<SUBMISSION_FILE>.json
git commit -m "Add submission for <HF_MODEL_NAME>"
git push

5. Open a pull request to the main branch of the repository via the Github interface.

6. Once the PR is review and merged, your submission will be added to the leaderboard!
