+# BERT-RTE Linear Classifier for EEE 486/586 Assignment
+
+This model is a fine-tuned version of `bert-base-uncased` on the RTE (Recognizing Textual Entailment) task from the GLUE benchmark. It was developed as part of the EEE 486/586 Statistical Foundations of Natural Language Processing course assignment.
+
+## Model Architecture
+
+Unlike the standard BERT classification approach, this model implements a custom architecture:
+
+- Uses BERT base model as the encoder for feature extraction
+- Replaces the standard single linear classification head with **multiple linear layers**:
+  - First expansion layer: hidden_size → hidden_size*2
+  - Intermediate layer with ReLU activation and dropout
+  - Final classification layer
+- Uses label smoothing of 0.1 in the loss function for better generalization
+
+## Performance
+
+The model achieves **70.40%** accuracy on the RTE validation set, with the following training dynamics:
+- Best validation accuracy: 70.40% (epoch 3)
+- Final validation accuracy: 69.68% (with early stopping)
+
+## Hyperparameters
+
+The model was optimized using Optuna hyperparameter search:
+
+| Hyperparameter | Value |
+|----------------|-------|
+| Learning rate | 1.72e-05 |
+| Max sequence length | 128 |
+| Dropout rate | 0.2 |
+| Hidden size multiplier | 2 |
+| Weight decay | 0.04 |
+| Batch size | 16 |
+| Training epochs | 6 (+2 for final model) |
+
+## Usage
+
+This model can be used for textual entailment classification (determining whether one text logically follows from another):
+
+```python
+from transformers import AutoTokenizer, AutoModelForSequenceClassification
+
+# Load model and tokenizer
+tokenizer = AutoTokenizer.from_pretrained("gal-lardo/BERT-RTE-LinearClassifier")
+model = AutoModelForSequenceClassification.from_pretrained("gal-lardo/BERT-RTE-LinearClassifier")
+
+# Prepare input texts
+premise = "The woman is sleeping on the couch."
+hypothesis = "There is a woman resting."
+
+# Tokenize and predict
+inputs = tokenizer(premise, hypothesis, return_tensors="pt", padding=True, truncation=True)
+outputs = model(**inputs)
+prediction = outputs.logits.argmax(-1).item()
+
+# Convert prediction to label
+label = "entailment" if prediction == 1 else "not_entailment"
+print(f"Prediction: {label}")
+```
