# RNAElectra: Single-Nucleotide ELECTRA-Style Pre-training for RNA Representation Learning
|
| 18 |
|
| 19 |
+
RNAElectra is a nucleotide-resolution RNA language model trained using an ELECTRA-style objective for efficient and discriminative representation learning. The model produces contextualized embeddings for RNA sequences and is designed for downstream transcriptomic and regulatory modeling tasks.
|
| 20 |
+
|
| 21 |
+
## Model Details
|
| 22 |
+
|
| 23 |
+
- **Model Type**: Transformer-based discriminator model
|
| 24 |
+
- **Training Objective**: ELECTRA-style replaced-token detection
|
| 25 |
+
- **Resolution**: Single-nucleotide
|
| 26 |
+
- **Domain**: RNA and transcriptomic sequences
|
| 27 |
+
- **Architecture**: ModernBERT-style backbone adapted for nucleotide sequences
|
| 28 |
+
|
| 29 |
+
RNAElectra focuses on efficient pre-training by learning to discriminate corrupted tokens rather than reconstruct them, leading to strong representations with improved training efficiency.
|
| 30 |
+
|
| 31 |
+
## Key Features
|
| 32 |
+
|
| 33 |
+
- Single-nucleotide tokenization
|
| 34 |
+
- Contextual RNA sequence embeddings
|
| 35 |
+
- ELECTRA-style discriminative pre-training
|
| 36 |
+
- Suitable for RNA function prediction, RBP binding modeling, stability prediction, regulatory element analysis, and downstream fine-tuning tasks
|
| 37 |
+
|
| 38 |
+
## Usage
|
| 39 |
+
|
| 40 |
+
### Basic Feature Extraction
|
| 41 |
|
| 42 |
```python
|
| 43 |
import torch
|
|
|
|
| 50 |
"FreakingPotato/RNAElectra",
|
| 51 |
trust_remote_code=True
|
| 52 |
).to(device)
|
| 53 |
+
model.eval()
|
| 54 |
|
| 55 |
tokenizer = NucEL_Tokenizer.from_pretrained(
|
| 56 |
"FreakingPotato/RNAElectra",
|
|
|
|
| 58 |
)
|
| 59 |
|
| 60 |
sequence = "AUGCAUGCAUGCAUGC"
|
| 61 |
+
|
| 62 |
inputs = tokenizer(sequence, return_tensors="pt")
|
| 63 |
inputs = {k: v.to(device) for k, v in inputs.items()}
|
| 64 |
|
|
|
|
| 66 |
outputs = model(**inputs)
|
| 67 |
|
| 68 |
embeddings = outputs.last_hidden_state
|
| 69 |
+
print(f"Sequence embeddings shape: {embeddings.shape}")
|
| 70 |
+
```
|
| 71 |
+
|
| 72 |
+
## Installation
|
| 73 |
+
|
| 74 |
+
```bash
|
| 75 |
+
pip install transformers torch
|
| 76 |
+
```
|
| 77 |
+
|
| 78 |
+
## Requirements
|
| 79 |
+
|
| 80 |
+
- transformers >= 5.0.0
|
| 81 |
+
- torch >= 2.10.0
|
| 82 |
+
- Python >= 3.12.3
|
| 83 |
+
|
| 84 |
+
GPU is recommended for large-scale inference.
|
| 85 |
+
|
| 86 |
+
## Pre-training Overview
|
| 87 |
+
|
| 88 |
+
RNAElectra was trained using an ELECTRA-style generator–discriminator framework. A generator predicts corrupted tokens, and a discriminator learns to detect replaced tokens. Only the discriminator weights are released in this repository. This objective improves training efficiency compared to masked language modeling while preserving strong contextual representations.
|
| 89 |
+
|
| 90 |
+
## Intended Use
|
| 91 |
+
|
| 92 |
+
RNAElectra is intended for feature extraction, downstream fine-tuning, and representation learning in RNA and transcriptomic modeling tasks. It is not intended for clinical decision-making or medical diagnostics.
