+# Emotion Detection Model for MindPadi (`emotion_model`)
+
+This model is part of the **MindPadi** ecosystem — a mental health chatbot designed to offer empathetic, context-aware responses. `emotion_model` is a transformer-based sequence classification model trained to detect a range of emotional states from user input. It helps personalize chatbot responses by understanding the emotional tone of each message.
+
+
+
+## 🧠 Model Summary
+
+- **Task:** Emotion Classification
+- **Architecture:** Transformer-based (likely BERT or DistilBERT)
+- **Labels:** `happy`, `sad`, `angry`, `neutral`, `fearful`, `disgust`, `surprised`, etc.
+- **Framework:** 🤗 Transformers (PyTorch backend)
+- **Use Case:** Core emotion recognition module in `app/chatbot/emotion.py`
+
+
+
+## 🧾 Intended Use
+
+### ✔️ Primary Use Cases
+- Detect user emotions in chat messages.
+- Adjust response tone and therapy prompts in MindPadi.
+- Support emotional trend tracking in mood analytics.
+
+### 🚫 Not Recommended For
+- Clinical diagnosis or treatment decisions.
+- Emotion detection in highly formal or technical language (e.g., legal, medical).
+- Non-English inputs (English-only training data).
+
+
+
+## 📚 Training Details
+
+- **Training Script:** `training/train_emotion_model.py`
+- **Datasets:** A mix of publicly available emotion corpora (e.g., GoEmotions) and proprietary datasets stored in `training/datasets/`
+- **Preprocessing:**
+  - Cleaned for offensive language and class imbalance.
+  - Tokenized using `AutoTokenizer` from Hugging Face Transformers.
+- **Hyperparameters:**
+  - Epochs: ~4–6
+  - Batch Size: 16–32
+  - Learning Rate: 2e-5 to 3e-5
+- **Loss Function:** CrossEntropyLoss
+- **Optimizer:** AdamW
+
+
+
+## ✅ Evaluation
+
+- **Metrics:** Accuracy, F1-score (micro, macro), confusion matrix
+- **Evaluation Script:** `training/evaluate_model.py`
+- **Performance:**
+  - Accuracy: ~87%
+  - Macro F1: ~85%
+  - Robust across common emotional states like `sad`, `happy`, `angry`
+- **Visualization:** See `lstm_accuracy_bert.png` for comparisons

+## 📦 Files
+
+The model directory includes:
+
+| File | Purpose |
+|------|---------|
+| `config.json` | Model architecture configuration |
+| `model.safetensors` | Trained model weights |
+| `tokenizer.json`, `vocab.txt` | Tokenizer config |
+| `merges.txt` (if BPE-based) | Byte-pair encoding rules |
+| `checkpoint-*/` (optional) | Intermediate training checkpoints |
+
+
+
+## 🔍 Example Usage
+
+```python
+from transformers import AutoTokenizer, AutoModelForSequenceClassification
+import torch
+
+model_name = "mindpadi/emotion_model"
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = AutoModelForSequenceClassification.from_pretrained(model_name)
+
+text = "I feel so overwhelmed and tired."
+inputs = tokenizer(text, return_tensors="pt")
+outputs = model(**inputs)
+predicted_class = torch.argmax(outputs.logits, dim=1).item()
+
+print("Predicted emotion class:", predicted_class)
+````
+
+
+
+## 💡 Integration
+
+Integrated in:
+
+* `app/chatbot/emotion.py`: Emotion detection during each chat turn.
+* `app/utils/analytics.py`: Aggregates emotions for weekly mood charts.
+* `LangGraph`: Used in flow state personalization nodes.
+
+
+
+## ⚠️ Limitations
+
+* **Bias:** May inherit cultural or gender biases from training data.
+* **Language:** English only.
+* **False Positives:** Sarcasm or ambiguous text may confuse predictions.
+* **Not Clinical:** Should not be relied upon for medical-level emotional assessments.
+
+
+
+## 🧑‍⚖️ Ethical Considerations
+
+* MindPadi informs users that they are interacting with AI.
+* Emotion analysis is used only to guide and personalize chatbot responses.
+* All usage must respect user privacy (see `app/tools/encryption.py` for encryption methods).
