📥 Loading the Model

You can load the model directly using the Hugging Face Transformers library:

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForMaskedLM.from_pretrained(model_name)

🚀 Quickstart Examples

1. Masked Language Modeling
Predict missing words in sentences:

from transformers import pipeline

mask_filler = pipeline("fill-mask", model="boltuix/NeuroBERT-Pro", tokenizer="boltuix/NeuroBERT-Pro")
sentence = "The smart fan will [MASK] automatically when it gets hot."
results = mask_filler(sentence)

for r in results:
    print(f"Prediction: {r['token_str']}, Score: {r['score']:.4f}")

# Example Output:
# Prediction: turn, Score: 0.4600

🧪 Evaluation

NeuroBERT-Pro was evaluated on a masked language modeling task using 10 IoT-related sentences. The model predicts the top-5 tokens for each masked word, and a test passes if the expected word is in the top-5 predictions.

Sample Results:

Sentence: "She is a [MASK] at the local hospital."
Expected: nurse
Top-5 Predictions: nurse, doctor, surgeon, technician, assistant
Result: ✅ PASS

Sentence: "Turn off the lights after [MASK] minutes."
Expected: five
Top-5 Predictions: five, ten, three, fifteen, twenty
Result: ✅ PASS

Total Passed: ~10/10 (depends on fine-tuning, highest accuracy in the NeuroBERT family due to largest capacity).

💡 Use Cases

Smart Home Devices: Parse complex commands like “Turn [MASK] the coffee machine” (predicts “on”) or “The fan will turn [MASK]” (predicts “off”).
IoT Sensors: Interpret detailed sensor contexts, e.g., “The drone collects data using onboard [MASK]” (predicts “sensors”).
Wearables: Real-time intent detection, e.g., “The music pauses when someone [MASK] the room” (predicts “enters”).
Mobile Apps: Advanced offline chatbots or semantic search, e.g., “She is a [MASK] at the hospital” (predicts “nurse”).
Voice Assistants: Sophisticated local command parsing, e.g., “Please [MASK] the door” (predicts “shut”).

🖥️ Hardware Requirements

Processors: High-performance CPUs, GPUs, or advanced NPUs (e.g., NVIDIA Jetson Xavier, high-end servers)
Storage: ~400MB for model weights (quantized for reduced footprint)
Memory: ~800MB RAM for inference
Environment: Offline or cloud-edge hybrid settings

🚀 Notes on Fine-Tuning and Dataset Requirements for NeuroBERT-Pro

🔧 Fine-tuning is optional:
The base NeuroBERT-Pro model is pretrained on extensive language tasks and performs exceptionally well out-of-the-box but can be fine-tuned for specific tasks like NER or QA.
You may fine-tune it on labeled task-specific data to further enhance accuracy.
📊 Dataset size and quality:
- For quick tests, very small datasets (tens of samples) can yield good results due to the model’s capacity.
- For optimal accuracy, aim for 100–500 labeled examples (e.g., 100–500 for NER, 500+ for QA).
- Diverse datasets enhance model generalization, though NeuroBERT-Pro requires less data than smaller models.
⏳ Training considerations:
- Minimal epochs (e.g., 2–3) are often sufficient due to the model’s robust capacity, with low risk of overfitting.
- Use a validation set to monitor progress.
- Apply early stopping or checkpoints to save the best model.
🛠️ Custom datasets:
- If public datasets don’t fit your needs (e.g., IoT domain), create your own labeled dataset.
- Quality annotation and clear labeling remain important.
🧠 Model architecture:
- NeuroBERT-Pro is the largest BERT variant in the NeuroBERT family, designed for high-performance edge devices or cloud-edge hybrids.
- Requires minimal fine-tuning, offering top-tier accuracy with high resource demands.
- Optimized for maximum performance, with unmatched accuracy potential.
📏 Recommended minimum dataset sizes (approximate):
- NER: 100–500 annotated sentences
- QA: 500+ question-context-answer triplets
🎯 Summary:
Fine-tuning on a high-quality dataset can further enhance NeuroBERT-Pro’s already exceptional performance. For domain-specific tasks, custom datasets are recommended. Always validate and use early stopping for best results.
