Function sigmoid

Calculate the sigmoid (logistic function) for each element in a Tensor. There is a method version of this static function: Tensor.sigmoid.

$$\frac{1}{1 + e^{-x}} : \forall x \in T$$

Example

  const t = sm.randn([1337])

  // equivalent calls
  const a = t.sigmoid()
  const b = sm.sigmoid(t)

Returns

• A new Tensor
