Within the modern ConvNet framework, we tailor the two feature mixers with conceptually simple yet effective depthwise convolutions to facilitate middle-order information across spatial and channel spaces respectively. We propose MogaNet, a new family of efficient ConvNets, to pursue informative context mining with preferable complexity-performance trade-offs, which shows excellent scalability and attains competitive results among state-of-the-art models with more efficient use of parameters on ImageNet and multifarious typical vision benchmarks, including COCO object detection, ADE20K semantic segmentation, 2D&3D human pose estimation, and video prediction.

Catalog

We plan to release implementations of MogaNet in a few months. Please watch us for the latest release. Currently, this repo is reimplemented according to our official implementations in OpenMixup, and we are working on cleaning up experimental results and code implementations. Models are released in GitHub / Baidu Cloud / Hugging Face.

• ImageNet-1K Training and Validation Code [code] [models] [Hugging Face 🤗]
• Downstream Transfer to Object Detection and Instance Segmentation on COCO [code] [models]
• Downstream Transfer to Semantic Segmentation on ADE20K [code] [models]
• Downstream Transfer to 2D Human Pose Estimation on COCO [code] (baseline models are supported)
• Downstream Transfer to 3D Human Pose Estimation [code] (baseline models will be supported)
• Downstream Transfer to Video Prediction on MMNIST [code] (baseline models are supported)
• Image Classification on Google Colab and Notebook Demo [here]

Image Classification

1. Installation

Please check INSTALL.md for installation instructions.

2. Training and Validation

See TRAINING.md for ImageNet-1K training and validation instructions, or refer to our OpenMixup implementations. We released pre-trained models on OpenMixup in moganet-in1k-weights. We have also reproduced ImageNet results with this repo and released args.yaml / summary.csv / model.pth.tar in moganet-in1k-weights. The parameters in the trained model can be extracted by code.

Here is a notebook demo of MogaNet which run the steps to perform inference with MogaNet for image classification.
