- 非常深的神经网络的问题

  • 非常深度网络的主要好处是它可以表示非常复杂的功能。它还可以学习许多不同抽象级别的特征,从边缘(在较浅的层,更接近输入)到非常复杂的特征(在更深的层,更接近输出)。
  • 但是,使用更深的网络并不总是有帮助。训练梯度的一个巨大障碍是梯度消失:非常深的网络通常有一个梯度信号,很快就会归零,从而使梯度下降变得非常慢。
  • 更具体地说,在梯度下降期间,当您从最后一层反向传播回第一层时,您将乘以每一步的权重矩阵,因此梯度可以呈指数级迅速减小到零(或者在极少数情况下,指数级快速增长并“爆炸”,因为获得非常大的值)。
  • 因此,在训练过程中,您可能会看到随着训练的进行,较浅层的梯度的大小(或范数)会非常迅速地减小到零,如下所示:

构建一个残差网络

深度学习之残差网络插图1

 

 

  • 左图显示了通过网络的“主要路径”。右侧的图像将快捷方式添加到主路径。通过将这些 ResNet 块堆叠在一起,您可以形成一个非常深的网络。
  • 讲座提到,使用带有快捷方式的 ResNet 块也使其中一个块学习恒等函数变得非常容易。这意味着您可以堆叠额外的 ResNet 块,而几乎没有损害训练集性能的风险。
  • 在这一点上,还有一些证据表明,学习恒等函数的便利性解释了ResNets的卓越性能,甚至超过了跳过连接对梯度消失的帮助。
  • ResNet 中使用两种主要类型的块,主要取决于输入/输出尺寸是相同还是不同。您将实现它们:“标识块”和“卷积块”。

恒等块(Identity block)

恒等块是 ResNet 中使用的标准块,对应于输入激活(例如a[L])与输出激活(例如a[L+!])具有相同维度的情况。为了充实 ResNet 身份块中发生的不同步骤,下面是一个显示各个步骤的替代图表:

深度学习之残差网络插图2

 

 

 上面的路径是“捷径”。较低的路径是“主要路径”。在此图中,请注意每层中的 CONV2D 和 ReLU 步骤。为了加快训练速度,添加了 BatchNorm 步骤。不要担心这很难实现 - 你会看到BatchNorm只是Keras中的一行代码!

在本练习中,您将实际实现此标识块的一个功能稍微强大的版本,其中跳过连接“跳过”3 个隐藏层而不是 2 个层。它看起来像这样:

深度学习之残差网络插图3

 

 

主路径的第一部分:

  • 第一个 CONV2D 具有F1形状为 (1,1) 和步幅为 (1,1) 的过滤器。它的填充是“有效的”。使用 0 作为随机统一初始化的种子:kernel_initializer = initializer(seed=0).
  • 第一个 BatchNorm 是规范化“channel”轴。
  • 然后应用 ReLU 激活函数。这没有超参数。

主路径的第二部分:

  • 第二个 CONV2D 具有F2形状(f,f)和步幅为 (1,1) 的过滤器。它的填充是“相同的”。使用 0 作为随机统一初始化的种子:kernel_initializer = initializer(seed=0)
  • 第二个 BatchNorm 是规范化“channel”轴。
  • 然后应用 ReLU 激活函数。这没有超参数。

主路径的第三部分:

  • 第三个 CONV2D 具有F3形状 (1,1) 和步幅为 (1,1) 的过滤器。它的填充是“相同的”。使用 0 作为随机统一初始化的种子:kernel_initializer = initializer(seed=0)
  • 第三个 BatchNorm 是规范化“channel”轴。
  • 然后应用 ReLU 激活函数。这没有超参数。

主路径的最后一部分:

  • 第 3 层 X 的X_shortcut和输出相加。
  • 提示:语法看起来像 Add()([var1,var2])
  • 然后应用 ReLU 激活函数。这没有超参数。

接下来我们就要实现残差网络的恒等块了

我们已将初始值设定项参数添加到函数中。此参数接收一个初始值设定项函数,类似于包 tensorflow.keras.initializers 或任何其他自定义初始值设定项中包含的函数。默认情况下,它将设置为random_uniform

请记住,这些函数接受种子参数,该参数可以是所需的任何值,但在此笔记本中必须将其设置为 0 才能进行评分。

下面是实际使用函数式 API 的强大功能来创建快捷方式路径的地方:

卷积块

ResNet“卷积块”是第二种块类型。当输入和输出维度不匹配时,可以使用这种类型的块。与标识块的区别在于快捷方式路径中有一个 CONV2D 层:

深度学习之残差网络插图4

 

 

  •  快捷路径中的 CONV2D 层用于将输入调整为不同的维度,以便尺寸在将快捷方式值添加回主路径所需的最终添加中匹配。(这与讲座中讨论的矩阵的作用类似。)
  • 例如,要将激活维度的高度和宽度减少 2 倍,可以使用步幅为 2 的 1x1 卷积。
  • 快捷方式路径上的 CONV2D 层不使用任何非线性激活函数。它的主要作用是仅应用一个(学习的)线性函数来减小输入的维度,以便维度与后面的加法步骤相匹配。
  • 对于前面的练习,出于评分目的需要额外的初始值设定项参数,并且默认情况下已将其设置为 glorot_uniform

主路径的第一个组成部分:

  • 第一个 CONV2D 具有F1个形状为 (1,1) 和步幅为 (s,s) 的过滤器。它的填充是“有效的”。使用 0 作为种子glorot_uniform kernel_initializer = 初始值设定项(seed=0)。
  • 第一个 BatchNorm 是规范化“通道”轴。
  • 然后应用 ReLU 激活函数。这没有超参数。

主路径的第二个组成部分:

  • 第二个 CONV2D 具有F2个形状 (f,f) 和步幅为 (1,1) 的过滤器。它的填充是“相同的”。使用 0 作为种子glorot_uniform kernel_initializer = 初始值设定项(seed=0)。
  • 第二个 BatchNorm 是规范化“通道”轴。
  • 然后应用 ReLU 激活函数。这没有超参数。

主路径的第三个组成部分:

  • 第三个 CONV2D 具有F3个形状为 (1,1) 和步幅为 (1,1) 的过滤器。它的填充是“有效的”。使用 0 作为种子glorot_uniform kernel_initializer = 初始值设定项(seed=0)。
  • 第三个 BatchNorm 是规范化“通道”轴。请注意,此组件中没有 ReLU 激活函数。

快捷方式路径:

  • CONV2D 具有F3个形状为 (1,1) 和步幅为 (s,s) 的过滤器。它的填充是“有效的”。使用 0 作为种子glorot_uniform kernel_initializer = 初始值设定项(seed=0)。
  • BatchNorm正在规范化“通道”轴。

最后一步:

  • 快捷方式和主路径值相加。
  • 然后应用 ReLU 激活函数。这没有超参数。

from outputs import ResNet50_summary

model = ResNet50(input_shape = (64, 64, 3), classes = 6)

实体化结束,下面我们对模型进行编译

model.compile(optimizer='adam', loss='categorical_crossentropy', metrics=['accuracy'])

接下来我们就是加载数据集并进行训练

X_train_orig, Y_train_orig, X_test_orig, Y_test_orig, classes = load_dataset()

# Normalize image vectors
X_train = X_train_orig / 255.
X_test = X_test_orig / 255.

# Convert training and test labels to one hot matrices
Y_train = convert_to_one_hot(Y_train_orig, 6).T
Y_test = convert_to_one_hot(Y_test_orig, 6).T

print ("number of training examples = " + str(X_train.shape[0]))
print ("number of test examples = " + str(X_test.shape[0]))
print ("X_train shape: " + str(X_train.shape))
print ("Y_train shape: " + str(Y_train.shape))
print ("X_test shape: " + str(X_test.shape))
print ("Y_test shape: " + str(Y_test.shape))
number of training examples = 1080
number of test examples = 120
X_train shape: (1080, 64, 64, 3)
Y_train shape: (1080, 6)
X_test shape: (120, 64, 64, 3)
Y_test shape: (120, 6)
model.fit(X_train, Y_train, epochs = 10, batch_size = 32)

我们对模型进行评估
preds = model.evaluate(X_test, Y_test)
print ("Loss = " + str(preds[0]))
print ("Test Accuracy = " + str(preds[1]))
4/4 [==============================] - 1s 31ms/step - loss: 0.4844 - accuracy: 0.8417
Loss = 0.4843602478504181
Test Accuracy = 0.8416666388511658
博主已经在手势数据集上训练了自己的RESNET50模型的权重,你可以使用下面的代码载并运行博主的训练模型,
pre_trained_model = tf.keras.models.load_model('resnet50.h5')

然后测试一下博主训练出来的权值:

preds = pre_trained_model.evaluate(X_test, Y_test)
print ("Loss = " + str(preds[0]))
print ("Test Accuracy = " + str(preds[1]))

使用自己的图片做测试

img_path = 'C:/Users/Style/Desktop/kun.png'
img = image.load_img(img_path, target_size=(64, 64))
x = image.img_to_array(img)
x = np.expand_dims(x, axis=0)
x = x/255.0
print('Input image shape:', x.shape)
imshow(img)
prediction = model.predict(x)
print("Class prediction vector [p(0), p(1), p(2), p(3), p(4), p(5)] = ", prediction)
print("Class:", np.argmax(prediction))
Input image shape: (1, 64, 64, 3)
Class prediction vector [p(0), p(1), p(2), p(3), p(4), p(5)] =  [[0.01301673 0.8742848  0.00662233 0.05449386 0.02079306 0.03078919]]
