Logistic Sigmoid Function Calculator Online

Explanation

The sigmoid function, which has the appearance of the letter "S," is a mathematical function that has the ability to transfer any real value to a range between 0 and 1. A logistic function is another name for the sigmoid function.
Y = 1 / 1+e -z
If z increases until it reaches a positive infinity, then the expected value of y will change to 1. But the expected value of y will be zero if the value of z decreases to negative infinity.
If the sigmoid function's result is more than 0.5, the label is classified as class 1 or positive, and if it is less than 0.5, it is classified as class 0 or negative.

How to calculate Signum Function with a calculator?

• You first need to enter the x₀(x-value of the sigmoid's midpoint) value in the input field with label "x₀"
• Then, enter the L (curve's maximum value) value in the input field with label "L"
• Then, enter the k (the steepness of the curve) value in the input field with label "k"
• Then, enter the x value in the input field with label "x"
• Then click on the submit button. The Logistic Sigmoid Function result will automatically appear in the specified result block.
