+        The spatial transformer network (STN) learns how to perform spatial transformations on the
+        input image in order to enhance the geometric invariance of the model. For example, it can
+        crop a region of interest, scale and correct the orientation of an image. It can be a useful
+        mechanism because CNNs are not invariant to rotation and scale and more general affine
+        transformations.
+
+        The spatial transformer network boils down to three main components:
+
+        - The localization network is a regular CNN which regresses the transformation parameters.
+          The transformation is never learned explicitly from this dataset, instead the network
+          learns automatically the spatial transformations that enhances the global accuracy.
+        - The grid generator generates a grid of coordinates in the input image corresponding
+          to each pixel from the output image.
+        - The sampler uses the parameters of the transformation and applies it to the input image.
+
+        Here, we are going to implement an STN that performs affine transformations on the input images.

+\section{计算题（15 分）}
+\subsection{
+已知某卷积层的输入为$X$(该批量中样本数目为1，输入样本通道数为1)，采用一个卷积核$W$，即卷积输出通道数为1，卷积核尺寸为$2\times 2$，卷积的步长为1，无边界延拓，偏置量为$b$：
+$$X=\left[ \begin{array}{ccc}
+    0.5 & -0.2 & 0.3 \\
+    0.6 & 0.4 & -0.1 \\
+    -0.4 & 0.5 & 0.2
+\end{array}\right],
+W=\left[ \begin{array}{cc}
+    0.1 & -0.2  \\
+    -0.3 & 0.4
+\end{array}\right], b=0.04$$
+}
+\subsubsection{请计算卷积层的输出$Y$。}
+\[\begin{cases}
+    Y_{11} = 0.5 \times 0.1 + (-0.2) \times (-0.2) + 0.6 \times (-0.3) +  0.4 \times 0.4 + 0.04 = 0.11\\
+    Y_{12} = (-0.2) \times 0.1 + 0.3 \times (-0.2) + 0.4 \times (-0.3) + (-0.1) \times 0.4  + 0.04 = -0.2\\
+    Y_{21} = 0.6 \times 0.1 + 0.4 \times (-0.2) + (-0.4) \times (-0.3) + 0.5 \times 0.4 + 0.04 = 0.34\\
+    Y_{22} = 0.4 \times 0.1 + (-0.1) \times (-0.2) + 0.5 \times (-0.3) + 0.2 \times 0.4 + 0.04 = 0.03
+\end{cases}\]
+
+\subsubsection{若训练过程中的目标函数为$L$，且已知$\frac{\partial L}{\partial Y}=\left[ \begin{array}{cc}
+    0.3 & 0.1 \\
+    -0.4 & 0.2
+\end{array} \right]$，请计算$\frac{\partial L}{\partial X}$。
+}
+
+注：本题的计算方式不限，但需要提供计算过程以及各步骤的结果。
+\vspace{6mm}
+
+\begin{proof}[解]
+    首先，
+    \[\frac{\partial L}{\partial Y} = \begin{bmatrix}
+        \frac{\partial L}{\partial Y_{11}} & \frac{\partial L}{\partial Y_{12}}\\
+        \frac{\partial L}{\partial Y_{21}} & \frac{\partial L}{\partial Y_{22}}
+    \end{bmatrix}\]
+    \[\frac{\partial L}{\partial X} = \begin{bmatrix}
+        \frac{\partial L}{\partial X_{11}} & \frac{\partial L}{\partial X_{12}} & \frac{\partial L}{\partial X_{12}}\\
+        \frac{\partial L}{\partial X_{21}} & \frac{\partial L}{\partial X_{22}} & \frac{\partial L}{\partial X_{23}}\\
+        \frac{\partial L}{\partial X_{31}} & \frac{\partial L}{\partial X_{32}} & \frac{\partial L}{\partial X_{33}}
+    \end{bmatrix}\]
+    同时，根据链式法则，
+    \[\frac{\partial L}{\partial X_{11}} = \frac{\partial Y_{11}}{\partial X_{11}} \frac{\partial L}{\partial Y_{11}} + \frac{\partial Y_{12}}{\partial X_{11}} \frac{\partial L}{\partial Y_{12}} + \frac{\partial Y_{21}}{\partial X_{11}} \frac{\partial L}{\partial Y_{21}} + \frac{\partial Y_{22}}{\partial X_{11}} \frac{\partial L}{\partial Y_{22}}\]
+    其它的$\frac{\partial L}{X_{12}}, \dots, \frac{\partial L}{\partial X_{33}}$的计算方式也是类似的。因此，
+    \[\frac{\partial L}{\partial X} = \sum_{i = 1}^2 \sum_{j = 1}^2
+    \begin{bmatrix}
+        \frac{\partial Y_{ij}}{\partial X_{11}} & \cdots & \frac{\partial Y_{ij}}{\partial X_{13}}\\
+        \vdots & \ddots & \vdots\\
+        \frac{\partial Y_{ij}}{\partial X_{31}} & \cdots & \frac{\partial Y_{ij}}{\partial X_{33}}
+    \end{bmatrix} \frac{\partial L}{\partial Y_{ij}} = \sum_{i = 1}^2 \sum_{j = 1}^2 \frac{\partial Y_{ij}}{\partial X} \frac{L}{\partial Y_{ij}}\]
+    式中的$\frac{\partial Y_{ij}}{\partial X}$与对应元是由哪几个$X$中的元素卷积得到有关，它们是$W$在$3 \times 3$矩阵中的平移。综合起来，有
+    \begin{align*}
+        \frac{\partial L}{\partial X} & =
+        \begin{bmatrix}

+        & = \mathrm{zeropad}(W) \ast \frac{\partial L}{\partial Y}\\

+\section{编程作业报告}
+\subsection{探究batch normalization和dropout的作用}
+\begin{enumerate}
+    \item 使用默认配置训练模型：
+    \begin{lstlisting}[style=Bash]
+python train.py --ckpt_path checkpoints/default
+    \end{lstlisting}
+    \begin{figure}[H]
+        \centering
+        \includegraphics[width=\linewidth]{img/models/default/loss_and_acc.jpg}
+    \end{figure}
+    之后测试得到的正确率为90.8\%。
+    \item 启用batch normalization：
+    \begin{lstlisting}[style=Bash]
+python train.py --ckpt_path checkpoints/bn --bn
+    \end{lstlisting}
+    \begin{figure}[H]
+        \centering
+        \includegraphics[width=\linewidth]{img/models/bn/loss_and_acc.jpg}
+    \end{figure}
+    测试得到的正确率为95.9\%。
+    \item 启用dropout并设置概率为0.3：
+    \begin{lstlisting}[style=Bash]
+python train.py --ckpt_path checkpoints/dropout --dropout 0.3
+    \end{lstlisting}
+    \begin{figure}[H]
+        \centering
+        \includegraphics[width=\linewidth]{img/models/dropout/loss_and_acc.jpg}
+    \end{figure}
+    测试后得到的正确率为94.1\%。
+\end{enumerate}
+
+\subsection{探究数据增广的作用}
+考虑到在不同的视角下，交通标志可能有旋转或者变形，因此使用
+\begin{lstlisting}[style=Python]
+transforms.RandomAffine(degrees=30,shear=10)
+\end{lstlisting}
+来对数据进行随机的形变与旋转；另外，考虑到可能在不同的光线条件下导致对比度变化，因此使用
+\begin{lstlisting}[style=Python]
+transforms.RandomAutocontrast()
+\end{lstlisting}
+来对数据进行随机的对比度调整。
+
+执行
+\begin{lstlisting}[style=Bash]
+python unit_test.py data_loader
+\end{lstlisting}
+得到
+\begin{figure}[H]
+    \centering
+    \includegraphics[width=\linewidth]{img/augmentation.jpg}
+    \caption{数据增广后的结果}
+\end{figure}
+
+训练最优模型使用的命令为
+\begin{lstlisting}[style=Bash]
+python train.py --ckpt_path checkpoints/bn_aug --bn --augment --epoch 20
+\end{lstlisting}
+\begin{figure}[H]
+    \centering
+    \includegraphics[width=\linewidth]{img/models/bn_aug/loss_and_acc.jpg}
+\end{figure}
+测试得到的正确率为96.0\%，略微高于不使用数据增强时的结果。
+
+\subsection{探究空间变换网络（STN）的作用}
+运行
+\begin{lstlisting}[style=Bash]
+python train.py --ckpt_path checkpoints/stn --bn --stn
+\end{lstlisting}
+\begin{figure}[H]
+    \centering
+    \includegraphics[width=\linewidth]{img/models/stn/loss_and_acc.jpg}
+\end{figure}
+测试得到的正确率为94.6\%。正确率比不使用stn反而有所降低，可能是设计的网络结构不够理想导致的。
+
+\subsection{可视化}
+\begin{enumerate}
+    \item 可视化各层卷积核：

+        \caption{第4层的卷积核}
+    \end{figure}
+    \item 可视化各层卷积层的输出特征图
+    \begin{figure}[H]
+        \centering
+        \includegraphics[width=\linewidth]{img/feature/layer_0/feature_map.jpg}

+    \end{figure}
+    \begin{figure}[H]

+        \includegraphics[width=\linewidth]{img/feature/layer_2/feature_map.jpg}
+        \caption{第2层的卷积核特征图}
+    \end{figure}
+    \begin{figure}[H]

+        \includegraphics[width=\linewidth]{img/feature/layer_4/feature_map.jpg}
+        \caption{第4层的卷积核特征图}
+    \end{figure}
+    \item t-SNE可视化最后一层隐藏层的输出特征
+    \begin{figure}[H]
+        \centering
+        \includegraphics[width=\linewidth]{img/tsne/tsne.jpg}
+    \end{figure}
+    t-SNE最后一层的隐藏层的输出证明，不同类别的输入已经被通过非线性变换分类到了不同的聚类。
+    \item STN学习到的变换
+    \begin{figure}[H]
+        \centering
+        \includegraphics[width=\linewidth]{img/stn/stn.jpg}
+    \end{figure}
+    网络尽可能将所有的路牌都变换到了同样的倾斜角度。
+\end{enumerate}
+
+\section{遇到的问题与解决办法}
+在自定义STN网络的时候，我最开始使用了比较小的卷积核，使得STN的效果很差，使用之后会使得正确率只有80\%；之后，我分析认为STN主要要感知整个图片的倾斜以及旋转情况，需要较大的视野，因此选择了较大的卷积核，之后得到了比较理想的效果。
+
+完成作业没有使用大模型。
