tf.raw_ops.BoostedTreesCenterBias
Stay organized with collections Save and categorize content based on your preferences.
Calculates the prior from the training data (the bias) and fills in the first node with the logits' prior. Returns a boolean indicating whether to continue centering.
tf.raw_ops.BoostedTreesCenterBias(
tree_ensemble_handle, mean_gradients, mean_hessians, l1, l2, name=None
)
Args |
|---|

l1 | A Tensor of type float32. l1 regularization factor on leaf weights, per instance based. |
l2 | A Tensor of type float32. l2 regularization factor on leaf weights, per instance based. |
name | A name for the operation (optional). |
Returns |
|---|
A Tensor of type bool. |
