tfr.keras.utils.log2_inverse

Computes 1./log2(1+x) element-wise for each label.

tfr.keras.utils.log2_inverse(
    rank: tfr.keras.model.TensorLike
) -> tf.Tensor

Can be used to define rank_discount_fn for tfr.keras.metrics.NDCGMetric.

Args
rank	A Tensor or anything that can be converted to a tensor using tf.convert_to_tensor.

Returns
A Tensor that has each input element transformed as x to 1./log2(1+x).
