摘要: 深度学习已经广泛应用到各个领域, 如计算机视觉和自然语言处理等, 并都取得了明显优于早期机器学习算法的效果. 在信息技术飞速发展的今天, 训练数据逐渐趋于大数据集, 深度神经网络不断趋于大型化, 导致训练越来越困难, 速度和精度都有待提升. 2013年, Ioffe等指出训练深度神经网络过程中存在一个严重问题: 中间协变量迁移(Internal covariate shift), 使网络训练过程对参数初值敏感、收敛速度变慢, 并提出了批归一化(Batch normalization, BN)方法, 以减少中间协变量迁移问题, 加快神经网络训练过程收敛速度. 目前很多网络都将BN作为一种加速网络训练的重要手段, 鉴于BN的应用价值, 本文系统综述了BN及其相关算法的研究进展. 首先对BN的原理进行了详细分析. BN虽然简单实用, 但也存在一些问题, 如依赖于小批量数据集的大小、训练和推理过程对数据处理方式不同等, 于是很多学者相继提出了BN的各种相关结构与算法, 本文对这些结构和算法的原理、优势和可以解决的主要问题进行了分析与归纳. 然后对BN在各个神经网络领域的应用方法进行了概括总结, 并且对其他常用于提升神经网络训练性能的手段进行了归纳. 最后进行了总结, 并对BN的未来研究方向进行了展望.Abstract: Deep learning has been widely applied to various fields, such as computer vision and natural language processing, and has achieved much better results than earlier machine learning. Today, with the rapid development of information technology, deep neural networks are trained with larger data sets, and the network depth is deepening, making training complicated and speed or accuracy need to be improved. In 2013, Ioffe et al. pointed out that there is a serious problem in the training process of deep neural network, i.e., internal covariate shift. It slows down the training for requiring careful parameter initialization and smaller learning rate. Ioffe et al. put forward batch normalization (BN) to reduce the effect of internal covariate shift, to accelerate the convergence speed of training neural networks. At present, many networks use BN as an important approach to accelerate training. In view of the application value of BN, this paper systematically reviews the research progress of BN and its related algorithms. Firstly, the theory of BN is analyzed. Although BN is simple and helpful, there are also some problems, such as relying on the size of mini-batch, training and inference process are in different ways. Therefore, many scholars have proposed a variety of algorithms based on BN, the advantages and main function of those algorithms are analyzed and summarized. Then, the applications of BN in various neural network fields are summarized. And we sum up other methods to improve the training performance of neural network. At last, we give a summation to whole paper, and point out the future development tendency and research direction of BN.

归一化方法 收敛速度
(训练周期)计算量 优势 缺点 应用领域 未加归一化的
网络– – – – – 批归一化 (BN) 相比于未加批归一化的网络, 收敛速度加快10倍以上 适中 减少网络训练过程中的中间协变量迁移问题, 使网络训练过程对参数初始值不再敏感, 可以使用更高的学习率进行训练, 加快网络训练过程收敛速度 依赖 mini-batch 数据集的大小, 训练和推理时计算过程不同 在CNN、分片线性神经网络等FNN中效果较好, 对RNN促进效果相对较差 归一化传播 (NormProp) 比BN更稳定、收敛速度明显更快 少于BN 减少中间协变量迁移现象, 不依赖于mini-batch数据集大小, 网络中每一层的输出都服从正态分布, 训练和推理阶段计算过程相同 没有正则化效果, 也不能和其他正则化手段如Dropout
共用理论上可以应用到使用任何激活函数、目标函数的网络, 网络可以使用任何梯度传播算法进行训练, 但具体效果还需要进一步
证实批量重归一化 (BR) mini-batch数据集中含有的数据量很少或包含服从非独立同分布的样本时, 比BN更稳定, 收敛更快 计算量稍多于BN 减少中间协变量迁移现象, 使网络训练对参数初值不再敏感, 可以使用更高的学习率进行训练, mini-batch中数据量很少或服从非独立同分布时, 使用BR的网络性能明显优于使用BN的网络,收敛速度更快, 训练精度更高 计算量稍多于BN 在mini-batch数据量很少或包含服从非独立同分布的样例时, 应用效果优于BN 逐步归纳批量归一化 (DBN) 比BN更稳定, 收敛速度类似BN 计算量多于BN 减少中间协变量迁移, 将神经网络的训练和推理过程关联起来, 使得网络在训练时不仅考虑当前使用的mini-batch数据集, 会同时考虑过去网络训练使用过的mini-batch数据集 对mini-batch数据集仍有一定的依赖性 理论上可以应用BN的网络, 都可以应用DBN, 但是因为没有从根本上克服BN的问题, 在应用上同样会受到一定的限制 层归一化 (LN) 比BN鲁棒性强, 收敛速度更快 计算量少于BN LN对每一层内的神经元使用单一样例进行归一化, 在训练和推理阶段计算过程相同, 应用到在线学习任务和RNN中的效果明显优于其他归一化方法, 可减少训练时间, 提升网络性能 在CNN等神经网络中的效果不如BN 层归一化对于稳定RNN中的隐层状态很有效, 可进一步推广, 但在CNN等前馈神经网络中的效果不如BN 连接边权值行向量归一化 (WN) 比BN收敛速度更快 计算量少于BN 对mini-batch数据集没有依赖性, 不需要对过去处理过的情况进行记忆, 计算复杂度低. 网络训练和推理时计算过程相同, 不会像BN一样引入过多噪声 对网络没有正则化效果 可以更好地应用到RNN和一些对噪声敏感的网络中, 如深度强化学习和深度生成式模型, 这些模型中使用BN的效果都不够好 自归一化神经网络 (SNN) – 适中 使用SeLU构造网络, 输入数据经过SNN的多层映射后, 网络中每一层输出的均值和方差可以收敛到固定点, 具有归一化特性, 网络鲁棒性强 需要使用特定的激活函数SeLU才能构成网络, 在网络中使用dropout等手段会破坏网络结构, 使网络失去自归一化特性 理论上可以构建任何前馈神经网络和递归神经网络, 但网络需要使用SeLU激活函数, 且不能破坏对数据均值和方差的逐层特征映射
