## Quickstart: Masked Language Modeling

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

```python
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:

```python
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**:
```plaintext
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.

| Please [MASK] the door before leaving. | shut |
| The drone collects data using onboard [MASK]. | sensors |
| The fan will turn [MASK] when the room is empty. | off |
| Turn [MASK] the coffee machine at 7 AM. | on |
| The hallway light switches on during the [MASK]. | night |
| The air purifier turns on due to poor [MASK] quality. | air |
| The AC will not run if the door is [MASK]. | open |
| Turn off the lights after [MASK] minutes. | five |
| The music pauses when someone [MASK] the room. | enters |

*Note*: Metrics vary based on hardware (e.g., Raspberry Pi 4, Android devices) and fine-tuning. Test on your target device for accurate results.

## Use Cases

NeuroBERT-Pro is designed for **cutting-edge intelligence** in **edge and IoT scenarios**, delivering unparalleled NLP accuracy on resource-constrained devices. Key applications include:

- **Smart Home Devices**: Parse highly nuanced commands like “Turn [MASK] the coffee machine” (predicts “on”) or “The fan will turn [MASK]” (predicts “off”).
- **IoT Sensors**: Interpret intricate sensor contexts, e.g., “The drone collects data using onboard [MASK]” (predicts “sensors”).
- **Wearables**: Real-time intent detection with high precision, e.g., “The music pauses when someone [MASK] the room” (predicts “enters”).
- **Mobile Apps**: Offline chatbots or semantic search with near-BERT-base accuracy, e.g., “She is a [MASK] at the hospital” (predicts “nurse”).
- **Voice Assistants**: Local command parsing with exceptional accuracy, e.g., “Please [MASK] the door” (predicts “shut”).

Fine-tuning on domain-specific data is recommended for optimal results.

## Fine-Tuning Guide

To adapt NeuroBERT-Pro for custom IoT tasks (e.g., specific smart home commands):

1. **Prepare Dataset**: Collect labeled data (e.g., commands with intents or masked sentences).
2. **Fine-Tune with Hugging Face**:
   ```python
   #!pip uninstall -y transformers torch datasets
   #!pip install transformers==4.44.2 torch==2.4.1 datasets==3.0.1

   import torch
   from transformers import BertTokenizer, BertForSequenceClassification, Trainer, TrainingArguments
   from datasets import Dataset
   import pandas as pd

   # 1. Prepare the sample IoT dataset
   data = {
       "text": [
           "Turn on the fan",
           "Switch off the light",
           "Invalid command",
           "Activate the air conditioner",
           "Turn off the heater",
           "Gibberish input"
       ],
       "label": [1, 1, 0, 1, 1, 0]  # 1 for valid IoT commands, 0 for invalid
   }
   df = pd.DataFrame(data)
   dataset = Dataset.from_pandas(df)

   # 2. Load tokenizer and model
   model_name = "boltuix/NeuroBERT-Pro"  # Using NeuroBERT-Pro
   tokenizer = BertTokenizer.from_pretrained(model_name)
   model = BertForSequenceClassification.from_pretrained(model_name, num_labels=2)

   # 3. Tokenize the dataset
   def tokenize_function(examples):
       return tokenizer(examples["text"], padding="max_length", truncation=True, max_length=64)  # Short max_length for IoT commands

   tokenized_dataset = dataset.map(tokenize_function, batched=True)

   # 4. Set format for PyTorch
   tokenized_dataset.set_format("torch", columns=["input_ids", "attention_mask", "label"])

   # 5. Define training arguments
   training_args = TrainingArguments(
       output_dir="./iot_neurobert_results",
       num_train_epochs=5,  # Increased epochs for small dataset
       per_device_train_batch_size=2,
       logging_dir="./iot_neurobert_logs",
       logging_steps=10,
       save_steps=100,
       evaluation_strategy="no",
       learning_rate=1e-5,  # Adjusted for NeuroBERT-Pro
   )

   # 6. Initialize Trainer
   trainer = Trainer(
       model=model,
       args=training_args,
       train_dataset=tokenized_dataset,
   )

   # 7. Fine-tune the model
   trainer.train()

   # 8. Save the fine-tuned model
   model.save_pretrained("./fine_tuned_neurobert_iot")
   tokenizer.save_pretrained("./fine_tuned_neurobert_iot")

   # 9. Example inference
   text = "Turn on the light"
   inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True, max_length=64)
   model.eval()
   with torch.no_grad():
       outputs = model(**inputs)
       logits = outputs.logits
       predicted_class = torch.argmax(logits, dim=1).item()
   print(f"Predicted class for '{text}': {'Valid IoT Command' if predicted_class == 1 else 'Invalid Command'}")
   ```
3. **Deploy**: Export the fine-tuned model to ONNX or TensorFlow Lite for edge devices.
