When dealing with complex functions, we usually need to code a lot to build a complex Neural Network . Therefore, in order to make it easier for users to build complex network models, we provide some common basic function modules to simplify the user’s code and reduce development costs. These modules are usually composed of fine-grained functions combined based on certain logics. For implementation, please refer to nets .
simple_img_conv_pool is got by concatenating api_fluid_layers_conv2d with api_fluid_layers_pool2d . This module is widely used in image classification models, such as the MNIST number classification.

img_conv_group is composed of api_fluid_layers_conv2d , api_fluid_layers_batch_norm, api_fluid_layers_dropout and api_fluid_layers_pool2d. This module can implement the combination of multiple api_fluid_layers_conv2d , api_fluid_layers_batch_norm , api_fluid_layers_dropout and a single api_fluid_layers_pool2d. Among them, the number of api_fluid_layers_conv2d , api_fluid_layers_batch_norm and api_fluid_layers_dropout can be controlled separately, resulting in various combinations. This module is widely used in more complex image classification tasks, such as VGG.

sequence_conv_pool is got by concatenating api_fluid_layers_sequence_conv with api_fluid_layers_sequence_pool. The module is widely used in the field of natural language processing and speech recognition . Models such as the text classification model , TagSpace and Multi view Simnet.

The full name of
glu is Gated Linear Units, which originates from the paper Language Modeling with Gated Convolutional Networks . It consists of api_fluid_layers_split , api_fluid_layers_sigmoid and api_fluid_layers_elementwise_mul. It divides the input data into 2 equal parts, calculates the Sigmoid of second part, and then performs dot product of the sigmoid vlaue with the first part to get the output.

scaled_dot_product_attention originates from the paper Attention Is All You Need , mainly composed of api_fluid_layers_fc and api_fluid_layers_softmax . For the input data
Values, calculate the
Attention according to the following formula.
