deepxde.nn.paddle.deeponet module¶
-
class
deepxde.nn.paddle.deeponet.
DeepONet
(layer_sizes_branch, layer_sizes_trunk, activation, kernel_initializer, use_bias=True)[source]¶ Bases:
deepxde.nn.paddle.nn.NN
Deep operator network.
Parameters: - layer_sizes_branch – A list of integers as the width of a fully connected network, or (dim, f) where dim is the input dimension and f is a network function. The width of the last layer in the branch and trunk net should be equal.
- layer_sizes_trunk (list) – A list of integers as the width of a fully connected network.
- activation – If activation is a
string
, then the same activation is used in both trunk and branch nets. If activation is adict
, then the trunk net uses the activation activation[“trunk”], and the branch net uses activation[“branch”].

DeepONetCartesianProd
(layer_sizes_branch, layer_sizes_trunk, activation, kernel_initializer, regularization=None)[source]¶ Bases:
deepxde.nn.paddle.nn.NN
Deep operator network for dataset in the format of Cartesian product.
Parameters: - layer_sizes_branch – A list of integers as the width of a fully connected network, or (dim, f) where dim is the input dimension and f is a network function. The width of the last layer in the branch and trunk net should be equal.
- layer_sizes_trunk (list) – A list of integers as the width of a fully connected network.
- activation – If activation is a
string
, then the same activation is used in both trunk and branch nets. If activation is adict
, then the trunk net uses the activation activation[“trunk”], and the branch net uses activation[“branch”].
deepxde.nn.paddle.fnn module¶
-
class
deepxde.nn.paddle.fnn.
FNN
(layer_sizes, activation, kernel_initializer)[source]¶ Bases:
deepxde.nn.paddle.nn.NN
Fully-connected neural network.
-
class
deepxde.nn.paddle.fnn.
PFNN
(layer_sizes, activation, kernel_initializer)[source]¶ Bases:
deepxde.nn.paddle.nn.NN
Parallel fully-connected network that uses independent sub-networks for each network output.
Parameters: - layer_sizes – A nested list that defines the architecture of the neural network (how the layers are connected). If layer_sizes[i] is an int, it represents one layer shared by all the outputs; if layer_sizes[i] is a list, it represents len(layer_sizes[i]) sub-layers, each of which is exclusively used by one output. Note that len(layer_sizes[i]) should equal the number of outputs. Every number specifies the number of neurons in that layer.
- activation – A string represent activation used in fully-connected net.
- kernel_initializer – Initializer for the kernel weights matrix.
deepxde.nn.paddle.msffn module¶
-
class
deepxde.nn.paddle.msffn.
MsFFN
(layer_sizes, activation, kernel_initializer, sigmas, dropout_rate=0)[source]¶ Bases:
deepxde.nn.paddle.nn.NN
Multi-scale fourier feature networks.
Parameters: sigmas – List of standard deviation of the distribution of fourier feature embeddings. References

STMsFFN
(layer_sizes, activation, kernel_initializer, sigmas_x, sigmas_t, dropout_rate=0)[source]¶ Bases:
