class dlpy.layers.OutputLayer(name=None, act='softmax', fcmp_act=None, fcmp_err=None, error=None, init=None, std=None, mean=None, truncation_factor=None, init_bias=None, n=None, n_softmax_samples=None, include_bias=None, target_std=None, full_connect=None, src_layers=None, **kwargs)

Output layer

Parameters

namestring, optional

Specifies the name of the layer.

actstring, optional

Specifies the activation function. Valid Values: AUTO, IDENTITY, LOGISTIC, SIGMOID, TANH, RECTIFIER, RELU, SOFPLUS, ELU, LEAKY, FCMP Default: AUTO

fcmp_actstring, optional

Specifies the FCMP activation function for the layer.

fcmp_errstring, optional

Specifies the FCMP error function for the output layer.

errorint, optional

Specifies the error function. This function is also known as the loss function. Valid Values: AUTO, GAMMA, NORMAL, POISSON, ENTROPY, CTC, FCMPERR, CTC_ALT Default: AUTO

initstring, optional

Specifies the initialization scheme for the layer. Valid Values: XAVIER, UNIFORM, NORMAL, CAUCHY, XAVIER1, XAVIER2, MSRA, MSRA1, MSRA2 Default: XAVIER

stdfloat, optional

Specifies the standard deviation value when the init parameter is set to NORMAL.

meanfloat, optional

Specifies the mean value when the init parameter is set to NORMAL.

truncation_factorfloat, optional

Specifies the truncation threshold (truncationFactor x std), when the init parameter is set to NORMAL

init_biasfloat, optional

Specifies the initial bias for the layer.

nint, optional

Specifies the number of neurons in the output layer. By default, the number of neurons is automatically determined when the model training begins. The specified value cannot be smaller than the number of target variable levels.

n_softmax_samplesint, optional

Specifies the number of samples used in sampled Softmax.

include_biasbool, optional

Includes bias neurons. Default: True

target_stdint, optional

Specifies how to standardize the variables in the output layer. Valid Values: MIDRANGE, NONE, STD Default: NONE

full_connectbool, optional

In default, the output layer is fully connected to all the previous layers. When it is false, the output layer becomes a loss function layer. Default: True

src_layersiter-of-Layers, optional

Specifies the layers directed to this layer.
