在本教程中，您将学习如何通过使用来自预训练网络的迁移学习来对猫和狗的图像进行分类。
预训练模型是一个保存的网络，它之前是在大型数据集上进行训练的，通常用于大规模图像分类任务。您可以按原样使用预训练模型，也可以使用迁移学习针对特定任务对该模型进行定制。
图像分类中迁移学习背后的直觉是：如果一个模型是在足够大且通用的数据集上进行训练的，那么该模型将有效地充当视觉世界的通用模型。这样，您就可以利用这些已学习到的特征图，而无需通过在大型数据集上从头开始训练大型模型来重新开始。
在本笔记本中，您将尝试两种定制预训练模型的方法：
特征提取：使用先前网络学习到的表示形式从新样本中提取有意义的特征。您只需在预训练模型之上添加一个新的分类器（将从头开始训练），以便重新利用先前为该数据集学习到的特征图。
您不需要（重新）训练整个模型。基础卷积网络已经包含了对分类图片通用的特征。然而，预训练模型的最终分类部分是针对原始分类任务特定的，因此也是针对模型训练所用的那组类别的。
微调：解冻已冻结模型库顶部的几层，并联合训练新添加的分类器层和基础模型的最后几层。这使我们能够“微调”基础模型中高阶特征表示，使其与特定任务更加相关。
您将遵循通用的机器学习工作流程。
- 检查并理解数据
- 构建输入流水线，本例中使用 Keras ImageDataGenerator
- 组合模型
- 加载预训练的基础模型（及预训练权重）
- 在其之上堆叠分类层
- 训练模型
- 评估模型

由于原始数据集不包含测试集，您需要创建一个。为此，请使用 tf.data.experimental.cardinality 确定验证集中有多少批次数据可用，然后将其中 20% 移动到测试集中。
val_batches = tf.data.experimental.cardinality(validation_dataset)
test_dataset = validation_dataset.take(val_batches // 5)
validation_dataset = validation_dataset.skip(val_batches // 5)
print('Number of validation batches: %d' % tf.data.experimental.cardinality(validation_dataset))
print('Number of test batches: %d' % tf.data.experimental.cardinality(test_dataset))
Number of validation batches: 26 Number of test batches: 6
配置数据集以获得高性能
使用缓冲预取（buffered prefetching）从磁盘加载图像，以避免 I/O 阻塞。要了解有关此方法的更多信息，请参阅数据性能指南。
AUTOTUNE = tf.data.AUTOTUNE
train_dataset = train_dataset.prefetch(buffer_size=AUTOTUNE)
validation_dataset = validation_dataset.prefetch(buffer_size=AUTOTUNE)
test_dataset = test_dataset.prefetch(buffer_size=AUTOTUNE)
使用数据增强
当您没有大型图像数据集时，通过对训练图像应用随机但逼真的变换（例如旋转和水平翻转）来人为增加样本的多样性是一种很好的做法。这有助于模型接触训练数据的不同方面并减少过拟合。您可以在此教程中了解更多关于数据增强的信息。
data_augmentation = tf.keras.Sequential([
tf.keras.layers.RandomFlip('horizontal'),
tf.keras.layers.RandomRotation(0.2),
])
让我们重复地将这些层应用于同一张图像并查看结果。
for image, _ in train_dataset.take(1):
plt.figure(figsize=(10, 10))
first_image = image[0]
for i in range(9):
ax = plt.subplot(3, 3, i + 1)
augmented_image = data_augmentation(tf.expand_dims(first_image, 0))
plt.imshow(augmented_image[0] / 255)
plt.axis('off')
缩放像素值
稍后，您将下载 tf.keras.applications.MobileNetV2 用作您的基础模型。该模型期望像素值在 [-1, 1] 之间，但此时您的图像像素值在 [0, 255] 之间。要缩放它们，请使用模型中包含的预处理方法。
preprocess_input = tf.keras.applications.mobilenet_v2.preprocess_input
rescale = tf.keras.layers.Rescaling(1./127.5, offset=-1)
从预训练的卷积网络创建基础模型
您将从 Google 开发的 MobileNet V2 模型创建基础模型。该模型在 ImageNet 数据集上进行了预训练，这是一个包含 140 万张图像和 1000 个类别的大型数据集。ImageNet 是一个研究性训练数据集，包含各种各样的类别，如 波罗蜜 (jackfruit) 和 注射器 (syringe)。这种知识库将帮助我们根据特定的数据集对猫和狗进行分类。
首先，您需要选择要用于特征提取的 MobileNet V2 层。最后一个分类层（在“顶部”，因为大多数机器学习模型图都是从底向上绘制的）并不是很有用。相反，您将遵循通常的做法，依赖于展平操作（flatten）之前的最后一层。这一层被称为“瓶颈层 (bottleneck layer)”。与最终/顶部层相比，瓶颈层的特征保留了更多的通用性。
首先，实例化一个预加载了 ImageNet 训练权重的 MobileNet V2 模型。通过指定 include_top=False 参数，您加载的网络将不包含顶部的分类层，这非常适合特征提取。
# Create the base model from the pre-trained model MobileNet V2
IMG_SHAPE = IMG_SIZE + (3,)
base_model = tf.keras.applications.MobileNetV2(input_shape=IMG_SHAPE,
include_top=False,
weights='imagenet')

此特征提取器将每张 160x160x3 的图像转换为 5x5x1280 的特征块。让我们看看它对一批示例图像的处理效果。

feature_batch = base_model(image_batch)

特征提取
在此步骤中，您将冻结在上一步中创建的卷积基，并将其用作特征提取器。此外，您在其之上添加一个分类器并训练该顶层分类器。
冻结卷积基
在编译和训练模型之前冻结卷积基非常重要。冻结（通过设置 layer.trainable = False）可以防止给定层中的权重在训练期间被更新。MobileNet V2 有许多层，因此将整个模型的 trainable 标志设置为 False 将冻结所有层。
base_model.trainable = False
关于 BatchNormalization 层的注意事项
许多模型包含 tf.keras.layers.BatchNormalization 层。这是一个特殊情况，在微调上下文中需要采取预防措施，本教程稍后会展示。
当您设置 layer.trainable = False 时，BatchNormalization 层将以推理模式运行，并且不会更新其均值和方差统计信息。
当为了微调而解冻包含 BatchNormalization 层的模型时，您应该通过在调用基础模型时传入 training = False 来保持 BatchNormalization 层处于推理模式。否则，应用于不可训练权重的更新将破坏模型已学习到的内容。
有关更多详细信息，请参阅迁移学习指南。

添加分类头
为了根据特征块生成预测，使用 tf.keras.layers.GlobalAveragePooling2D 层对 5x5 空间位置进行平均，将每张图像的特征转换为一个 1280 元素的向量。
global_average_layer = tf.keras.layers.GlobalAveragePooling2D()
feature_batch_average = global_average_layer(feature_batch)
print(feature_batch_average.shape)
(32, 1280)
应用一个 tf.keras.layers.Dense 层将这些特征转换为每张图像的一个预测结果。这里不需要激活函数，因为此预测将被视为 logit，即原始预测值。正数预测为类别 1，负数预测为类别 0。
prediction_layer = tf.keras.layers.Dense(1, activation='sigmoid')
prediction_batch = prediction_layer(feature_batch_average)
print(prediction_batch.shape)
(32, 1)
通过使用 Keras 函数式 API 将数据增强、缩放、base_model 和特征提取器层链接起来构建模型。如前所述，由于我们的模型包含一个 BatchNormalization 层，请使用 training=False。
inputs = tf.keras.Input(shape=(160, 160, 3))
x = data_augmentation(inputs)
x = preprocess_input(x)
x = base_model(x, training=False)
x = global_average_layer(x)
x = tf.keras.layers.Dropout(0.2)(x)
outputs = prediction_layer(x)
model = tf.keras.Model(inputs, outputs)
model.summary()
MobileNet 中的 800 多万个参数是冻结的，但 Dense 层中有 1200 个可训练参数。这些参数分配在两个 tf.Variable 对象（权重和偏置）中。
len(model.trainable_variables)
2
tf.keras.utils.plot_model(model, show_shapes=True)
编译模型
在训练模型之前对其进行编译。由于有两个类别且输出为 Sigmoid，因此使用 BinaryAccuracy。
base_learning_rate = 0.0001
model.compile(optimizer=tf.keras.optimizers.Adam(learning_rate=base_learning_rate),
loss=tf.keras.losses.BinaryCrossentropy(),
metrics=[tf.keras.metrics.BinaryAccuracy(threshold=0.5, name='accuracy')])
训练模型
在训练 10 个周期 (epochs) 后，您应该在验证集上看到约 96% 的准确率。
initial_epochs = 10
loss0, accuracy0 = model.evaluate(validation_dataset)

学习曲线
让我们看看在使用 MobileNetV2 基础模型作为固定特征提取器时，训练和验证准确率/损失的学习曲线。
acc = history.history['accuracy']
val_acc = history.history['val_accuracy']
loss = history.history['loss']
val_loss = history.history['val_loss']
plt.figure(figsize=(8, 8))
plt.subplot(2, 1, 1)
plt.plot(acc, label='Training Accuracy')
plt.plot(val_acc, label='Validation Accuracy')
plt.legend(loc='lower right')
plt.ylabel('Accuracy')
plt.ylim([min(plt.ylim()),1])
plt.title('Training and Validation Accuracy')
plt.subplot(2, 1, 2)
plt.plot(loss, label='Training Loss')
plt.plot(val_loss, label='Validation Loss')
plt.legend(loc='upper right')
plt.ylabel('Cross Entropy')
plt.ylim([0,1.0])
plt.title('Training and Validation Loss')
plt.xlabel('epoch')
plt.show()
在较小程度上，这也是因为训练指标报告的是一个周期内的平均值，而验证指标是在周期结束后评估的，因此验证指标看到的是一个经过了更长一点训练的模型。
微调
在特征提取实验中，您只训练了 MobileNetV2 基础模型之上的一些层。预训练网络的权重在训练期间没有被更新。
进一步提高性能的一种方法是训练（或“微调”）预训练模型顶层的权重，并与您添加的分类器的训练一起进行。训练过程将强制权重从通用特征图调整为特定于该数据集的特征。
此外，您应该尝试微调少量的顶层，而不是整个 MobileNet 模型。在大多数卷积网络中，层数越高，其专业性就越强。最初的几层学习的是非常简单和通用的特征，这些特征适用于几乎所有类型的图像。随着层数升高，特征会越来越针对模型训练所用的数据集。微调的目标是使这些专用特征适应新数据集，而不是覆盖通用的学习内容。
解冻模型的顶层
您所需要做的就是解冻 base_model 并设置底层为不可训练。然后，您应该重新编译模型（这对于这些更改生效是必要的），并恢复训练。
base_model.trainable = True
# Let's take a look to see how many layers are in the base model
print("Number of layers in the base model: ", len(base_model.layers))
# Fine-tune from this layer onwards
fine_tune_at = 100
# Freeze all the layers before the `fine_tune_at` layer
for layer in base_model.layers[:fine_tune_at]:
layer.trainable = False
Number of layers in the base model: 154
编译模型
由于您正在训练一个大得多的模型并希望重新适应预训练权重，因此在此阶段使用较低的学习率非常重要。否则，您的模型可能会非常迅速地出现过拟合。
model.compile(loss=tf.keras.losses.BinaryCrossentropy(),
optimizer = tf.keras.optimizers.RMSprop(learning_rate=base_learning_rate/10),
metrics=[tf.keras.metrics.BinaryAccuracy(threshold=0.5, name='accuracy')])
model.summary()
len(model.trainable_variables)
56
继续训练模型
如果您之前训练到了收敛点，这一步将使您的准确率提高几个百分点。
fine_tune_epochs = 10
total_epochs = initial_epochs + fine_tune_epochs
history_fine = model.fit(train_dataset,
epochs=total_epochs,
initial_epoch=len(history.epoch),
validation_data=validation_dataset)

让我们看看在微调 MobileNetV2 基础模型的最后几层并训练顶层分类器时，训练和验证准确率/损失的学习曲线。验证损失远高于训练损失，因此您可能会得到一些过拟合。
由于新的训练集相对较小且类似于原始的 MobileNetV2 数据集，您也可能会遇到一些过拟合。
微调后，模型在验证集上的准确率几乎达到 98%。
acc += history_fine.history['accuracy']
val_acc += history_fine.history['val_accuracy']
loss += history_fine.history['loss']
val_loss += history_fine.history['val_loss']

plt.subplot(2, 1, 1)
plt.plot(acc, label='Training Accuracy')
plt.plot(val_acc, label='Validation Accuracy')
plt.ylim([0.8, 1])

评估与预测
最后，您可以使用测试集验证模型在新数据上的性能。
loss, accuracy = model.evaluate(test_dataset)
print('Test accuracy :', accuracy)
6/6 ━━━━━━━━━━━━━━━━━━━━ 0s 29ms/step - accuracy: 0.9600 - loss: 0.0837 Test accuracy : 0.96875
现在，您已经准备好使用此模型来预测您的宠物是猫还是狗了。
# Retrieve a batch of images from the test set
image_batch, label_batch = test_dataset.as_numpy_iterator().next()
predictions = model.predict_on_batch(image_batch).flatten()
predictions = tf.where(predictions < 0.5, 0, 1)
print('Predictions:\n', predictions.numpy())
print('Labels:\n', label_batch)
plt.figure(figsize=(10, 10))
for i in range(9):
ax = plt.subplot(3, 3, i + 1)
plt.imshow(image_batch[i].astype("uint8"))
plt.title(class_names[predictions[i]])
plt.axis("off")
Predictions: [1 0 0 0 1 1 1 1 0 1 1 1 0 1 1 0 1 1 1 1 1 0 0 1 1 1 1 1 1 0 0 0] Labels: [1 0 0 0 1 1 1 1 0 1 1 1 0 1 1 0 1 1 1 1 1 0 0 1 1 1 1 1 1 0 0 0]
总结
使用预训练模型进行特征提取：处理小数据集时，利用在同一领域较大数据集上训练的模型所学到的特征是一种常见的做法。这是通过实例化预训练模型并在其之上添加一个全连接分类器来完成的。预训练模型被“冻结”，训练期间只有分类器的权重会被更新。在这种情况下，卷积基提取了与每张图像相关的所有特征，您只是训练了一个分类器，根据那组提取出的特征来确定图像类别。
微调预训练模型：为了进一步提高性能，人们可能希望通过微调将预训练模型的顶层重新用于新数据集。在这种情况下，您调整了权重，使模型学习到了特定于该数据集的高级特征。当训练数据集较大且与预训练模型最初训练所用的数据集非常相似时，通常建议使用此技术。
