Sigma W

Sigma W. The align environment is used for two or more equations when vertical alignment is desired usually binary relations such as equal signs are alignedAmerican Mathematical Society For all intents and purposes the align environment is a replacement for the eqnarray environment and all its warts Rather than \\begin{eqnarray*} x^2 + y^2 &=& 1 \\\\ y &=& \\sqrt{1 x^2}.

Instead it’s $\sigma(w \cdot x+b)$ where $\sigma$ is called the sigmoid function* *Incidentally $\sigma$ is sometimes called the logistic function and this new class of neurons called logistic neurons It’s useful to remember this terminology since these terms are used by many people working with neural nets However we’ll stick with the sigmoid terminology.

In statistics the Fano factor like the coefficient of variation is a measure of the dispersion of a probability distribution of a Fano noiseIt is named after Ugo Fano an Italian American physicist The Fano factor is defined as = where is the variance and is the mean of a random process in some time window WThe Fano factor can be viewed as a kind of noisetosignal ratio it is a.
