## 📊 Hybrid Model Results (HMDB51)

The hybrid model (TimeSformer + RetNet) was also trained on the **HMDB51 dataset**.

Due to Kaggle’s runtime limitation, training was interrupted at **Epoch 12**, so results are reported up to **Epoch 11**. Training will be resumed in a later stage.

## 🏆 Best Performance (Current)

- **Validation Accuracy:** **66.14%**
- **F1 Score:** 0.6512  
- Achieved at **Epoch 10**

---

## ⚠️ Training Status

- Training **interrupted at Epoch 12** due to runtime limit
- Model will be **resumed from best checkpoint**
- Final performance may improve after full training

---

## ⚡ Efficiency

- Peak GPU Memory: **~7.2 GB**
- ~25% lower than standard TimeSformer
- Faster training per epoch

---

## 📌 Observations

- Steady improvement until Epoch 10  
- Slight plateau after that (possible early convergence)  
- Lower accuracy compared to UCF101 (expected due to dataset complexity)

---

## 🔄 Next Steps

- Resume training from Epoch 11 checkpoint  
- Complete remaining epochs  
- Compare final performance with baseline model
