Teacher Promotion and Progressive Shrinking: a Framework for Iterative Distillation

Abstract

Deep neural networks often achieve high accuracy, but their compute, memory, and power demands can hinder deployment on resource-constrained edge devices. This paper proposes an iterative, constraint-aware knowledge distillation framework that compresses a large model into a small one under an explicit model-size budget and a maximum allowable accuracy drop. Starting from user-specified constraints, the method trains candidate students, checks feasibility, and adjusts capacity across generations; oversized students may be promoted to intermediate teachers for subsequent distillation stages. Experiments on MNIST and Speech Commands validate the approach: on MNIST, a 100 KB target with a 2-point accuracy-drop budget yields a 55 KB student achieving 97.28% accuracy; on Speech Commands, a 4-point drop yields a 197.5 KB student reaching 94.08% accuracy. These results demonstrate predictable tradeoffs between compactness and accuracy, and show that multistage teacher promotion can bridge large capacity gaps while preserving performance within user-defined tolerances.

Architectural Inductive Bias in Knowledge Distillation: Disentangling Representational Similarity from Performance Transfer

Deploying deep learning models on resource-constrained edge devices necessitates a trade-off between computational efficiency and robustness. While Knowledge Distillation (KD) is widely used to compress large models into lightweight students, the impact of the Teacher’s architectural inductive bias on the Student’s saf...

Single-Teacher View Augmentation: Enhancing Knowledge Distillation with Student-Guided Perturbations

Shift-Augmented Knowledge Distillation (SAKD) is proposed, a simple yet effective framework that leverages the student's evolving features as a dynamic condition for perturbation generation, enabling single-stage training while producing adaptive, diverse views through a parameter-free cyclic shift.

Too much of a good thing -- when knowledge distillation promotes overfitting, and how to avoid it

This work proposes a student design based on simple, homogeneous blocks mirroring those of the teacher, distilling knowledge between corresponding blocks, showing that intermediate block-wise distillation, guided appropriately, is key to building compact data-efficient models without sacrificing accuracy.
