用python代码实现:除了导入Keras库,还需要导入Sequential、Conv3D、MaxPooling3D、Dropout、Flatten和Dense等具体的Keras库。根据下列代码:def createModel(): input_shape=(1, 22, 59, 114) model = Sequential() #C1 model.add(Conv3D(16, (22, 5, 5), strides=(1, 2, 2), padding='valid',activation='relu',data_format= "channels_first", input_shape=input_shape)) model.add(keras.layers.MaxPooling3D(pool_size=(1, 2, 2),data_format= "channels_first", padding='same')) model.add(BatchNormalization()) #C2 model.add(Conv3D(32, (1, 3, 3), strides=(1, 1,1), padding='valid',data_format= "channels_first", activation='relu'))#incertezza se togliere padding model.add(keras.layers.MaxPooling3D(pool_size=(1,2, 2),data_format= "channels_first", )) model.add(BatchNormalization()) #C3 model.add(Conv3D(64, (1,3, 3), strides=(1, 1,1), padding='valid',data_format= "channels_first", activation='relu'))#incertezza se togliere padding model.add(keras.layers.MaxPooling3D(pool_size=(1,2, 2),data_format= "channels_first", )) model.add(BatchNormalization()) model.add(Flatten()) model.add(Dropout(0.5)) model.add(Dense(256, activation='sigmoid')) model.add(Dropout(0.5)) model.add(Dense(2, activation='softmax')) opt_adam = keras.optimizers.Adam(lr=0.00001, beta_1=0.9, beta_2=0.999, epsilon=1e-08, decay=0.0) model.compile(loss='categorical_crossentropy', optimizer=opt_adam, metrics=['accuracy']) return model

Python-简单的Keras模型
这段代码定义了一个名为createModel()的函数。在函数内部,首先定义了一个五维输入张量的形状(即input_shape)。接下来,创建了一个名为model的Sequential对象,这是一个Keras模型容器,可以顺序堆叠多个网络层。除此之外,还需要导入Conv3D(三维卷积)、MaxPooling3D(三维最大池化)、Dropout(随机失活)等库,以及Flatten(扁平化)和Dense(全连接)等具体的Keras库来搭建这个模型。
