scfoundation-rde

Model Description

This is the RDE (Reaction-Diffusion Embedding) model from scFoundation. It provides specialized embeddings optimized for specific downstream tasks.

Model weights were originally from the biomap-research/scFoundation repository and have been re-uploaded here for ease of use with the perturblab library.

Model Details

• Model Type: RDE embedding model
• Architecture: xTrimoGene with MAE (Masked Autoencoder), Performer/Transformer modules
• Parameters: 100M parameters
• Training Data: 50M+ human single-cell transcriptomics data
• Input: Single-cell or bulk RNA-seq expression data (19,264 fixed genes)
• Output: RDE-optimized embeddings

Usage

from perturblab.model.scfoundation import scFoundationModel

# Load model
model = scFoundationModel.from_pretrained('scfoundation-rde', device='cuda')

# Generate embeddings
embeddings = model.predict_embedding(
    adata, 
    output_type='cell',
    pool_type='max'
)
