📷 Introduction

We build a series of tiny hybrid vision Mamba called TinyViM by integrating mobile-friendly convolution and efficient Laplace mixer. The proposed TinyViM achieves impressive performance on several downstream tasks including image classification, semantic segmentation, object detection and instance segmentation. In particular, TinyViM outperforms Convolution, Transformer and Mamba-based models with similar scales, and the throughput is about 2-3 times higher than that of other Mamba-based models.

🏆 Performance

1️⃣ Classification

Model	Type	Params (M)	GMACs	Throughput (im/s)	Top-1(300e/1000e)
TinyViM-S	CNN-Mamba	5.6	0.9	2563	79.2/80.3
TinyViM-B	CNN-Mamba	11.0	1.5	1851	81.2/82.1
TinyViM-L	CNN-Mamba	31.7	4.7	843	83.3/83.6

We have provided the checkpoints and training logs in the table above!

2️⃣ Detection & Instance Segmentation

Model	Head	AP-box	AP-mask
