Feature Based Distillation

Feature-based knowledge distillation aims to improve the performance of smaller, more efficient "student" neural networks by transferring knowledge from larger, more powerful "teacher" networks, focusing on the intermediate feature representations rather than just the final output. Current research explores various techniques to address challenges like architectural heterogeneity between teacher and student, handling uncertainty in teacher knowledge, and optimizing distillation for specific tasks (e.g., object detection, semantic segmentation, face recognition). This approach is significant because it enables the deployment of high-performing models on resource-constrained devices and improves the efficiency of training complex models, impacting diverse applications from image classification to speech processing.
