tf.math.abs(
x, name=None
)
Given a tensor of integer or floating-point values, this operation returns a tensor of the same type, where each element contains the absolute value of the corresponding element in the input.
Given a tensor x of complex numbers, this operation returns a tensor of typefloat32 or float64 that is the absolute value of each element in x. All elements in x must be complex numbers of the form \(a + bj\). The absolute value is computed as \( \sqrt{a^2 + b^2}\). For example:
x = tf.constant([[-2.25 + 4.75j], [-3.25 + 5.75j]])
tf.abs(x) # [5.25594902, 6.60492229]
| Args | |
|---|---|
| x | A Tensor or SparseTensor of type float16, float32, float64,int32, int64, complex64 or complex128. |
| name | A name for the operation (optional). |
| Returns |
|---|
| A Tensor or SparseTensor the same size, type, and sparsity as x with absolute values. Note, for complex64 or complex128 input, the returned Tensor will be of type float32 or float64, respectively.If x is a SparseTensor, returnsSparseTensor(x.indices, tf.math.abs(x.values, ...), x.dense_shape) |
