tf.contrib.learn.poisson_regression_head

Creates a Head for poisson regression. (deprecated)

tf.contrib.learn.poisson_regression_head(
    label_name=None, weight_column_name=None, label_dimension=1,
    enable_centered_bias=False, head_name=None
)

Args
label_name	String, name of the key in label dict. Can be null if label is a tensor (single headed models).
weight_column_name	A string defining feature column name representing weights. It is used to down weight or boost examples during training. It will be multiplied by the loss of the example.
label_dimension	Number of regression labels per example. This is the size of the last dimension of the labels Tensor (typically, this has shape [batch_size, label_dimension]).
enable_centered_bias	A bool. If True, estimator will learn a centered bias variable for each class. Rest of the model structure learns the residual after centered bias.
head_name	name of the head. If provided, predictions, summary and metrics keys will be suffixed by "/" + head_name and the default variable scope will be head_name.

Returns
An instance of Head for poisson regression.
