Geek Out Time: Knowledge Distillation in TensorFlow- Smaller, Smarter Models in Google Colab

In this Geek Out Time, we’ll explore knowledge distillation in TensorFlow, a technique that allows a smaller student model to learn from a larger teacher model — a concept widely used in cutting-edge AI models like DeepSeek-R1, which was distilled from the powerful DeepSeek-V3. We’ll demonstrate this using CIFAR-10, a standard computer vision dataset of 32×32 color images across 10 categories. Our teacher model achieves ~62.28% accuracy, and after distillation, the student model reaches ~54.67% — all while being much smaller and more efficient.

1. What is Knowledge Distillation?

Knowledge distillation is a technique where a large, well-trained model (the teacher) transfers its “dark knowledge” to a smaller, more efficient student model. Instead of just training the student with the dataset’s hard labels (like [0, 0, 1, 0, ..., 0] for class 2), we use the teacher model’s soft labels (the predicted probabilities for each class). These soft labels carry richer information about how the teacher ranks the classes—this guides the student model to learn more effectively than if it only had the one-hot ground truths.
