The sigmoid function is often used in neural networks (artificial intelligence) to "squish" values into a range between zero and one.

Error Function Calculator Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. The sigmoid function yields the following plot: Figure 1: Sigmoid function. If z represents the output of the linear layer of a model trained with logistic regression, then sigmoid(z) will yield a value (a probability) between 0 and 1. In mathematical terms: Graph of the Sigmoid Function. Looking at the graph, we can see that the given a number n, the sigmoid function would map that number between 0 and 1. As the value of n gets larger, the value of the sigmoid function gets closer and closer to 1 and as n gets smaller, the value of the sigmoid function is get closer and closer to 0. I am learning about machine learning from coursera. I am trying to calculate the sigmoid function and i have the below code: function g = sigmoid(z) %SIGMOID Compute sigmoid functoon % J = SIGMOID(z) computes the sigmoid of z. Here’s how you compute the derivative of a sigmoid function First, let’s rewrite the original equation to make it easier to work … Continue reading "How to Compute the Derivative of a Sigmoid Function (fully worked example)"

Nevertheless, it is hard to guess the parameters for a given problem. So, people use software such as Origin [1] or QtiPlot to fit. Personally, I use Origin/QtiPlot only for plotting and Excel/OO–Calc for evaluation/calculation, because both programs are much more comfortable and powerful. However, both lack the LOGIT function Description. LOGIT(p) returns the logit of the proportion p: The argument p must be between 0 and 1.. Example. LOGIT(0.9) returns 2.197224577 Calculator
