Creates a Head
for binary classification with SVMs. (deprecated)
tf.contrib.learn.binary_svm_head(
label_name=None, weight_column_name=None, enable_centered_bias=False,
head_name=None, thresholds=None
)
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.
