)
Defined in tensorflow/contrib/learn/python/learn/estimators/head.py.
Creates a Head for linear regression. (deprecated)
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 labelsTensor(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_nameand the default variable scope will behead_name.link_fn: link function to convert logits to predictions. If provided, this link function will be used instead of identity.
Returns:
An instance of Head for linear regression.
