  1. 去除全连接层: 传统的卷积神经网络(CNN)通常包含卷积层和全连接层。在这篇论文中,作者认识到全连接层会导致输出固定大小的特征向量,从而限制了CNN在图像语义分割任务中的应用。 因此,作者去除了CNN中的全连接层,将其替换为全卷积层,使得网络能够接受任意大小的输入图像,并输出相同尺寸的像素级别的分类结果。

激活函数(Activation Function),负责将神经元的输入映射到输出端,激活函数将神经网络中将输入信号的总和转换为输出信号。激活函数大多是非线性函数,才能将多层感知机的输出转换为非线性,使得神经网络可以任意逼近任何非线性函数,进而可以应用到众多的非线性模型中。

ARIMA (Autoregressive Integrated Moving Average)

It is a popular statistical analysis model used for forecasting time series data. ARIMA models are especially well-suited for short to medium-term forecasting models that have data with trends, seasonality, or cyclic patterns. The model aims to describe the autocorrelations in the data.
