Hey @MuaazOsaidTahir,
Thanks for bringing this question to the Google Cloud Community. I am learning alongside all of you! You can further fine-tune your existing model with a new batch of training material which is actually one of the game-changing benefits of fine-tuning. Here's why it works and how to approach it:
Why Fine-Tuning Works This Way:
- Knowledge Retention: When you fine-tune a model, you start with a pre-trained model that has already learned general patterns and features relevant to your task. Fine-tuning adjusts those existing weights rather than starting from completely random weights. This means your model retains the knowledge from the previous training.
- Efficiency: Further fine-tuning leverages the knowledge your model already has. This usually leads to faster convergence and better results with less data compared to training a new model from scratch.
How to Fine-Tune with New Data:
- Combine Datasets: Simply combine your original training data with your new batch of training material.
- Fine-Tune Again: Use the fine-tuning process on your existing fine-tuned model. Generally, you'll want to use a slightly lower learning rate than the initial fine-tuning as you're primarily making smaller adjustments.
- Save and Deploy: Save your further fine-tuned model for deployment or further use.
Important Considerations:
- Data Distribution: Ensure that your new data has a similar distribution to your original data. Significant differences in the data could potentially confuse the model and decrease performance.
- Overfitting: Be mindful of overfitting, especially if your new batch of data is small. You might need to adjust regularization or early stopping techniques.
I am by no means an expert in this area, so I encourage other's to jump in and share their perspective! Let me know if you have any specific scenarios or technologies in mind, and I can see if one of our internal SMEs can provide more tailored guidance!
