+# ESNet系列
+
+## 概述
+
+ESNet(Enhanced ShuffleNet)是百度自研的一个轻量级网络，该网络在ShuffleNetV2的基础上融合了MobileNetV3、GhostNet、PPLCNet的优点，组合成了一个在ARM设备上速度更快、精度更高的网络，由于其出色的表现，所以在PaddleDetection推出的[PP-PicoDet](https://github.com/PaddlePaddle/PaddleDetection/tree/release/2.3/configs/picodet)使用了该模型做backbone，配合更强的目标检测算法，最终的指标一举刷新了目标检测模型在ARM设备上的SOTA指标。
+
+## 精度、FLOPs和参数量
+
+| Models | Top1 | Top5 | FLOPs<br>(M) | Params<br/>(M) |
+|:--:|:--:|:--:|:--:|:--:|
+| ESNet_x0_25 | 62.48 | 83.46 | 30.9 | 2.83 |
+| ESNet_x0_5 | 68.82 | 88.04 | 67.3 | 3.25 |
+| ESNet_x0_75 | 72.24 | 90.45 | 123.7 | 3.87 |
