Soft shrink function.
activation_softshrink(x, lower = -0.5, upper = 0.5)
| x | A `Tensor`. Must be one of the following types: `float16`, `float32`, `float64`. |
|---|---|
| lower | `float`, lower bound for setting values to zeros. |
| upper | `float`, upper bound for setting values to zeros. Returns: A `Tensor`. Has the same type as `x`. |
A `Tensor`. Has the same type as `x`.
Computes soft shrink function: `x - lower if x < lower, x - upper if x > upper else 0`.
`x - lower if x < lower, x - upper if x > upper else 0`.
