We revitalize Densely Connected Convolutional Networks (DenseNets) and reveal their untapped potential to challenge the prevalent dominance of ResNet-style architectures. Our research indicates that DenseNets were previously underestimated, primarily due to conventional design choices and training methods that underexploited their full capabilities.

Key Highlights:

Pilot study (§5.1) reveals concatenations' effectiveness.
We have meticulously upgraded various aspects of DenseNets (§3.2) through architectural tweaks and block redesigns.
Our revitalized DenseNets (RDNets) outperform mainstream architectures such as Swin Transformer, ConvNeXt, and DeiT-III (§4.1).

Our work aims to reignite interest in DenseNets by demonstrating their renewed relevance and superiority in the current architectural landscape. We encourage the community to explore and build upon our findings, paving the way for further innovative contributions in deep learning architectures.

We believe that various architectural designs that have been popular recently would be combined with dense connections successfully.

Easy to use

RDNet is available on timm. You can easily use RDNet by installing the timm package.

import timm

model = timm.create_model('rdnet_large', pretrained=True)

For detailed usage, please refer to the huggingface model card.

Updates

(2024.07.24): Pip installable pacakge added.
(2024.04.19): Initial release of the repository.
(2024.03.28): Paper is available on arXiv.
