What is prot_t5_xl_half_uniref50-enc?
This model is a specialized half-precision version of the ProtT5-XL-UniRef50, designed specifically for efficient protein sequence embedding generation. Based on the t5-3b architecture, it's been optimized to work with minimal GPU memory requirements while maintaining performance quality. The model processes uppercase amino acid sequences to create meaningful protein representations.
Implementation Details
The model implements a modified T5 architecture, trained using a Bart-like MLM denoising objective with a 15% amino acid masking probability. It's particularly notable for its efficient memory usage, requiring only 8GB of video RAM.
- Encoder-only architecture for efficient embedding generation
- Half-precision (float16) parameters for reduced memory footprint
- Trained on extensive UniRef50 protein sequence database
- Supports batch processing of protein sequences
Core Capabilities
- Generation of per-residue protein embeddings (1024-dimensional)
- Creation of whole-protein representations
- Efficient processing of large protein sequences
- Support for batch processing of multiple sequences
Frequently Asked Questions
Q: What makes this model unique?
This model's uniqueness lies in its optimized half-precision implementation while maintaining the full capabilities of the original ProtT5-XL-UniRef50 model. It provides the same quality of protein embeddings but with significantly reduced memory requirements.
Q: What are the recommended use cases?
The model is ideal for creating amino-acid or protein embeddings in memory-constrained environments. It's particularly useful for downstream tasks such as protein structure prediction, function annotation, and protein property prediction.
