Final Review :
- The model has just memorized/overfitted on the data and is not working good on the samples outside the training data.
- Also looks like it has changed the base model weights by too much (catastrophic forgetting).
- Similar problems with the Epoch 6 model as well.
- Epoch 2 model couldn't find middle ground and not performing well on training data and not on new data as well and increasing just the Epochs is leading to memorization as stated above.
Conclusion :
- Need more quality data for the model to really learn the patterns. Increasing just the epochs with less data only leads to overfitting.
