php sigmoid function 1

php sigmoid function

function sigmoid($t){
    return 1 / (1 + exp(-$t));
}

Here is what the above code is Doing:
1. We’re defining a function called sigmoid that takes in a number t and returns the value of the sigmoid function applied to t.
2. We’re using the built-in exp function to calculate the exponential of t.
3. We’re using the built-in exp function to calculate the exponential of -t.
4. We’re dividing 1 by the sum of 1 and the exponential of -t.
