如何在tf.keras.Sequential()中调用网络?

在tf.keras.Sequential()中调用网络可以通过添加层的方式来构建网络模型。tf.keras.Sequential()是一个顺序模型,可以按照添加的顺序依次构建网络层。

首先,需要导入相关的库和模块:

代码语言:txt
复制
import tensorflow as tf
from tensorflow.keras.layers import Dense, Conv2D, MaxPooling2D, Flatten

然后,可以创建一个空的Sequential模型:

代码语言:txt
复制
model = tf.keras.Sequential()

接下来,可以通过add()方法逐层添加网络层。例如,添加一个全连接层:

代码语言:txt
复制
model.add(Dense(units=64, activation='relu'))

再添加一个卷积层:

代码语言:txt
复制
model.add(Conv2D(filters=32, kernel_size=(3, 3), activation='relu'))

继续添加其他层,如池化层、Flatten层等。

最后,可以通过compile()方法编译模型,并指定损失函数、优化器等参数:

代码语言:txt
复制
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])

完成以上步骤后,就可以使用该模型进行训练和预测了。

  • Building deep retrieval models

    In the featurization tutorial we incorporated multiple features into our models, but the models consist of only an embedding layer. We can add more dense layers to our models to increase their expressive power. In general, deeper models are capable of learning more complex patterns than shallower models. For example, our user model incorporates user ids and timestamps to model user preferences at a point in time. A shallow model (say, a single embedding layer) may only be able to learn the simplest relationships between those features and movies: a given movie is most popular around the time of its release, and a given user generally prefers horror movies to comedies. To capture more complex relationships, such as user preferences evolving over time, we may need a deeper model with multiple stacked dense layers.
