Abstract

In recent years, deep neural networks have been successful in both industry and academia, especially for computer vision tasks. The great success of deep learning is mainly due to its scalability to encode large-scale data and to maneuver billions of model parameters. However, it is a challenge to deploy these cumbersome deep models on devices with limited resources, e.g., mobile phones and embedded devices, not only because of the high computational complexity but also the large storage requirements. To this end, a variety of model compression and acceleration techniques have been developed. As a representative type of model compression and acceleration, knowledge distillation effectively learns a small student model from a large teacher model. It has received rapid increasing attention from the community. This paper provides a comprehensive survey of knowledge distillation from the perspectives of knowledge categories, training schemes, teacher–student architecture, distillation algorithms, performance comparison and applications. Furthermore, challenges in knowledge distillation are briefly reviewed and comments on future research are discussed and forwarded.

TL;DR

This paper surveys knowledge distillation (KD), covering knowledge categories, distillation schemes, teacher-student architectures, algorithms, performance comparisons, and applications. It concludes that KD is an effective and efficient model-compression technique, while identifying open challenges in theory, architecture design, and unified knowledge modeling.

Key findings

  • KD systems are organized around three knowledge types—response-based, feature-based, and relation-based—and three training schemes: offline, online, and self-distillation.
  • Performance comparisons on CIFAR10 and CIFAR100 show student improvements; for example, on CIFAR10 ACNs improve AlexNet from 73.24 to 78.57 (5.33↑), and on CIFAR100 TOFD improves ResNet50 from 77.42 to 84.74 (7.32↑).
  • Online collaborative learning and self-knowledge distillation are reported to significantly improve deep-model performance, and KD is widely applied in visual recognition, NLP, speech recognition, recommender systems, privacy, and adversarial defense.
  • The survey identifies challenges including insufficient theoretical/empirical understanding, poorly investigated teacher-student architecture design, and difficulty modeling different knowledge types in a unified complementary framework.

Methods

  • Design: a comprehensive survey of knowledge distillation from the perspectives of knowledge categories, training schemes, teacher-student architecture, distillation algorithms, performance comparison, and applications.
  • Data: reviews existing KD literature and compiles classification performance from original papers on CIFAR10 and CIFAR100, which contain 32×32 RGB images, 50,000 training images, and 10,000 testing images each, with 10 and 100 classes respectively.
  • Analysis: performance tables report accuracies and improvements over individually trained teacher/student baselines; the paper states these accuracies are directly derived from the corresponding original papers.

Limitations

  • Stated in the paper: theoretical and empirical understanding of KD remains insufficient, teacher-student architecture design is poorly investigated, and modeling different knowledge types in a unified complementary framework is still challenging.
  • Stated in the paper: the performance comparison relies on results directly taken from original papers rather than re-running all methods under one controlled experimental setup.
  • Evident from the text: the survey explicitly excludes a comprehensive review of model compression and acceleration outside knowledge distillation, and it does not describe a systematic literature-search protocol.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-06.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-06.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
