# 为什么SSD要比YOLO快？

SSD原文中说The fundamental improvement in speed comes from eliminating bounding box proposals and the subsequent pixel or feature resampling stage.能否详细说明下

penguin企 - 学习深度学习

fully connected layer for predictions instead of our convolutional predictors, and do not
explicitly consider multiple aspect ratios, we can approximately reproduce YOLO
yolo要再整个最顶层featuremap上预测，ssd只预测默认的anchor。另外，yolo后面还有一层全连接，ssd后面是卷积，应该卷积比较快
