**DetNet** is a backbone convolutional neural network for object detection. Different from traditional pre-trained models for ImageNet classification, DetNet maintains the spatial resolution of the features even though extra stages are included. DetNet attempts to stay efficient by employing a low complexity dilated bottleneck structure.

**Channel-wise Soft Attention** is an attention mechanism in computer vision that assigns "soft" attention weights for each channel $c$. In soft channel-wise attention, the alignment weights are learned and placed "softly" over each channel. This would contrast with hard attention which would only selects one channel to attend to at a time.

**DenseNAS-B** is a mobile convolutional neural network discovered through the [DenseNAS](https://paperswithcode.com/method/densenas) [neural architecture search](https://paperswithcode.com/method/neural-architecture-search) method. The basic building block is MBConvs, or inverted bottleneck residuals, from the [MobileNet](https://paperswithcode.com/method/mobilenetv2) architectures.
