## 🚀 Project Overview
The **Genomic-Transformer-Aphasia-Recovery** model is a specialized Sequence-to-Scalar Transformer designed to **predict biological recovery potential in stroke survivors**. By decoding 1024-nucleotide windows focused on neuroplasticity markers, the model estimates a patient's **Western Aphasia Battery-Aphasia Quotient (WAB-AQ)**.



This model serves as the **Biological Modality** of a multi-modal fusion pipeline. It is intended to be integrated with MRI-based lesion volumetry to provide clinicians with a holistic "Recovery Forecast."

## 🔬 Advancing Precision Neuro-Rehabilitation
This work represents a shift from "one-size-fits-all" therapy to **Data-Driven Personalized Care**. 

### 🧬 The Genomic Signal
While clinical assessments focus on the "Physical Damage" (lesion location), research in 2026 emphasizes that the patient's **Genomic Backdrop** determines the internal rate and "ceiling" of neural repair.
* **Activity-Dependent Plasticity:** By identifying variants in **BDNF**, **COMT**, and **APOE**, this model quantifies the efficiency of a patient's synaptic strengthening.
* **Proactive Intervention:** Identifying a "Structural Reliance" profile allows for earlier introduction of advanced therapies like **tDCS** or **closed-loop neural interfaces**.

Fine-tuned on a curated subset of the **Aphasia Recovery Cohort (ARC)**, consisting of 902 subjects. The model focuses on genetic regions associated with neuroplasticity and neural growth factor regulation.



## 🖥️ Usage & Inference
```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_id = "assix-research/genomic-transformer-aphasia-recovery"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id, trust_remote_code=True)

dna_seq = "ATGC..." # 1024bp sequence
inputs = tokenizer(dna_seq, return_tensors="pt")
with torch.no_grad():
    prediction = model(**inputs).logits.item()

print(f"Predicted WAB-AQ: {prediction:.2f}/100")
```

## ⚠️ Clinical Disclaimer

This model is a Biomedical Research Tool. Predicted WAB-AQ scores are statistical estimates and must be interpreted by a qualified neurologist in conjunction with structural neuroimaging (MRI/DTI).

## 💙 Dedication

This project is dedicated to Simon K.
While this model is built on code, data, and Blackwell silicon, its heart is rooted in the hope for recovery and the belief that the intersection of AI and Genomics can light the path home for those navigating the challenges of aphasia.

## 🤝 Call to the Research Community
**To the research community:** Let’s keep advancing this field. We have the architecture, the data, and the computing power, now we must have the persistence to turn these biological signals into real-world recovery for every patient who needs it.
