之前的教程，您应该有了一个常用模型，已经熟悉了数据读取接口。
现在可以自由创建优化器，写训练逻辑，用Pytorch很容易做到这些，而且能很容易让使用者看清训练逻辑。
同时，我们也提供标准训练器，是最简单的hook系统，帮助简化训练流程。
可以使用SimpleTrainer().train()做单损失，单优化器和单数据源训练。或者，也可以使用更多标准操作的DefaultTrainer().train()来优化训练。

基于Pre-trained模型，采用Post-training量化策略，能够在一定程度上弥补量化精度损失，并且避免了相对耗时的quantization-ware training或re-training过程。

WA与BC

"Data-Free Quantization through Weight Equalization and Bias Correction" 这篇文章提出了两种post-training策略，包括Weight Adjustment (WA)与Bias Correction (BC)。

Paper地址：

具体的WA策略如下所示，均衡调整通常在W1的output channel与W2的input channel之间进行：

调整系数计算如下，相邻tensors按channel均衡调整之后，分布范围将达到相一致的水平：

2. Bias Correction

Per-tensor或Per-channel量化的误差，直接体现在Conv2D等计算节点的输出产生了误差项：

沿channel c的误差项，可按前置BN层的参数予以估计：

将估计获得的误差项补偿回Bias，可提升一定的量化精度。

基于BN层的调整策略
"A Quantization-Friendly Separable Convolution for MobileNets" 这篇文章2提出了基于BN层的调整策略，即将BN层中趋于零的Variance替换为剩余Variance的均值，以消除对应通道输出的奇异性，从而获得对量化更为友好的Activation数值分布。

Batch Normalization: Accelerating Deep Network Training by Reducing Internal Covariate Shift
作者介绍了批次归一化，这是一种将单元激活归一化为网络中零均值和单元方差的技术。作者表明，在前馈和卷积网络中，批量归一化可加快训练速度并提高准确性。 BN还可以充当正则化器，从而减少对Dropout的需求。使用批标准化网络的集成，作者可以在ILSVRC上达到最先进的水平。
关键点

网络训练很复杂，因为随着较低层中的参数的变化，输入到较高层的值也会发生变化：内部协变量平移。解决方案：在网络内进行标准化。
BN：将输入归一化为非线性，以使均值和单位方差为零。然后，每单位添加两个附加参数（缩放和偏差）以保持网络的可表达性。统计数据是按小批量计算的。
网络参数增加，但幅度不大：每单位2个参数已应用批量归一化。
适用于完全连接和卷积的图层。作者没有尝试RNN。
添加BN时进行更改：提高学习率，删除/减少辍学率和l2正则化，加速学习率衰减，更彻底地整理训练示例。

DDR Training Motivation:As the clock frequency runs higher, the width of the data eye becomes narrower to sample data (channel signal integrity and jitter contribute to data eyereduction).
DDR training is introduced to remove static skew/noise so that the data eye is kept wider for better data sampling.
DDR Training动机：
随着时钟频率升高，数据眼的宽度变得更窄以采样数据（通道信号完整性和抖动有助于减少数据眼）。
引入了DDR Training以消除静态偏斜/噪声，从而使数据眼保持更大的范围，以进行更好的数据采样。
