Understanding the Effective Receptive Field in Deep Convolutional Neural Networks 理解深度卷积神经网络中的有效感受野 Abstract摘要 We study characteristics of receptive fields of units in deep convolutional networks. The receptive field size is a crucial issue in many vis…
Setting up the data and the model 前面我们介绍了一个神经元的模型,通过一个激励函数将高维的输入域权值的点积转化为一个单一的输出,而神经网络就是将神经元排列到每一层,形成一个网络结构,这种结构与我们之前介绍的线性模型不太一样,因此score function也需要重新定义,神经网络实现了一系列的线性映射与非线性映射,这一讲,我们主要介绍神经网络的数据预处理以及score function的定义. data processing 给定一个训练集,S={xi∈RD|i…
