tf.nn.elu

Computes the exponential linear function.

The ELU function is defined as:

  • \( e ^ x - 1 \) if \( x < 0 \)
  • \( x \) if \( x >= 0 \)

Examples:

tf.nn.elu(1.0)
<tf.Tensor: shape=(), dtype=float32, numpy=1.0>
tf.nn.elu(0.0)
<tf.Tensor: shape=(), dtype=float32, numpy=0.0>
tf.nn.elu(-1000.0)
<tf.Tensor: shape=(), dtype=float32, numpy=-1.0>

Args
features A Tensor. Must be one of the following types: half, bfloat16, float32, float64.
name A name for the operation (optional).
Returns
A Tensor. Has the same type as features.
