update ghostnet docs

MobileNetV3 is a new and lightweight network based on NAS proposed by Google in 2019. In order to further improve the effect, the activation functions of relu and sigmoid were replaced with hard_swish and hard_sigmoid activation functions, and some improved strategies were introduced to reduce the amount of network computing.
GhosttNet is a brand-new lightweight network structure proposed by Huawei in 2020. By introducing the ghost module, the problem of redundant calculation of features in traditional deep networks is greatly alleviated, which greatly reduces the amount of network parameters and calculations.

MobileNetV3是Google于2019年提出的一种基于NAS的新的轻量级网络,为了进一步提升效果,将relu和sigmoid激活函数分别替换为hard_swish与hard_sigmoid激活函数,同时引入了一些专门减小网络计算量的改进策略。
GhosttNet是华为于2020年提出的一种全新的轻量化网络结构,通过引入ghost module,大大减缓了传统深度网络中特征的冗余计算问题,使得网络的参数量和计算量大大降低。
