TANet: A Tiny Plankton Classification Network for Mobile Devices

الملخص EN

This paper is devoted to a lightweight convolutional neural network based on the attention mechanism called the tiny attention network (TANet).

The TANet consists of three main parts termed as a reduction module, self-attention operation, and group convolution.

The reduction module alleviates information loss caused by the pooling operation.

The new parameter-free self-attention operation makes the model to focus on learning important parts of images.

The group convolution achieves model compression and multibranch fusion.

Using the main parts, the proposed network enables efficient plankton classification on mobile devices.

The performance of the proposed network is evaluated on the Plankton dataset collected by Oregon State University’s Hatfield Marine Science Center.

The results show that TANet outperforms other deep models in speed (31.8 ms per image), size (648 kB, the size of the hard disk space occupied by the model), and accuracy (Top-1 76.5%, Top-5 96.3%).
