Area of Science:

• Computer Science
• Artificial Intelligence
• Machine Learning

Background:

• Deep learning models achieve high accuracy but require significant computational resources, hindering deployment in constrained environments like mobile devices.
• Existing methods for improving deep learning performance often involve increasing network depth or ensembling models, further exacerbating resource demands.
• There is a critical need for methods that enhance network performance without scaling up model size or complexity.

Purpose of the Study:

• To propose a cross-architecture online distillation approach for improving deep learning model performance.
• To address the challenge of deploying deep learning models in resource-constrained scenarios.
• To enhance network performance without expanding network scale.

Main Methods:

• A cross-architecture online distillation technique is proposed, transmitting supplementary information between networks of different structures.
• An ensemble method aggregates diverse network structures to create superior 'teacher' models for distillation.
• Discontinuous distillation with progressively enhanced constraints replaces traditional fixed distillation to preserve information diversity.

Main Results:

• The proposed method significantly improves the performance of various deep learning models, including AlexNet, VGG, ResNet, and DenseNet.
• Accuracy improvements were observed on benchmark datasets such as CIFAR10, CIFAR100, and ImageNet.
• The approach demonstrated superior results compared to traditional knowledge distillation methods, validating its effectiveness.

Conclusions:

• The cross-architecture online distillation method effectively enhances deep learning model performance.
• The technique offers a viable solution for deploying high-performing models in resource-limited environments.
• This research contributes to the advancement of efficient deep learning model training and deployment.
