- Access the model at boltuix/NeuroBERT-Pro.
- Download the model files (~150MB) or clone the repository:
```
git clone https://huggingface.co/boltuix/NeuroBERT-Pro
```

Via Transformers Library:

Load the model directly in Python:

from transformers import AutoModelForMaskedLM, AutoTokenizer
model = AutoModelForMaskedLM.from_pretrained("boltuix/NeuroBERT-Pro")
tokenizer = AutoTokenizer.from_pretrained("boltuix/NeuroBERT-Pro")

Manual Download:
- Download quantized model weights from the Hugging Face model hub.

Quickstart: Masked Language Modeling

Predict missing words in IoT-related sentences with masked language modeling:

from transformers import pipeline

# Unleash the power
mlm_pipeline = pipeline("fill-mask", model="boltuix/NeuroBERT-Pro")

# Test the magic
result = mlm_pipeline("Please [MASK] the door before leaving.")
print(result[0]["sequence"])  # Output: "Please open the door before leaving."

Quickstart: Text Classification

Perform intent detection or text classification for IoT commands:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# 🧠 Load tokenizer and classification model
model_name = "boltuix/NeuroBERT-Pro"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)
model.eval()

# 🧪 Example input
text = "Turn off the fan"

# ✂️ Tokenize the input
inputs = tokenizer(text, return_tensors="pt")

# 🔍 Get prediction
with torch.no_grad():
    outputs = model(**inputs)
    probs = torch.softmax(outputs.logits, dim=1)
    pred = torch.argmax(probs, dim=1).item()

# 🏷️ Define labels
labels = ["OFF", "ON"]

# ✅ Print result
print(f"Text: {text}")
print(f"Predicted intent: {labels[pred]} (Confidence: {probs[0][pred]:.4f})")

Output:

Text: Turn off the fan
Predicted intent: OFF (Confidence: 0.8921)

Note: Fine-tune the model for specific classification tasks to further enhance accuracy.

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. With its flagship architecture, NeuroBERT-Pro achieves near-perfect performance.
