rdnet 0.1.2

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.

Tradeoff with RDNet (ours) and SOTA models

Tradeoff with RDNet (ours) and mainstream models

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

Install rdnet package with pip install rdnet !

import timm
import rdnet  # this will register the RDNet models to timm

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

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