    enable_centered_bias=False,
    head_name=None,
    thresholds=None
)

Defined in tensorflow/contrib/learn/python/learn/estimators/head.py.

Creates a Head for binary classification with SVMs.

The head uses binary hinge loss.

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.
• 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.
• thresholds: thresholds for eval metrics, defaults to [.5]

Returns:

An instance of Head for binary classification with SVM.
