Maximum Likelihood Estimation
The method of maximum likelihood estimation allows to estimate point parameters for a given distribution underlying some observed data. Let’s look at an example to understand what this means:Imagine you

The Sigmoid and its Derivative
The sigmoid function, \(\sigma(x)\), is also called the logistic function, or expit [1]. It is the inverse of the logit function. Its function definition is: \[ \sigma(x) = \frac{1}{1+e^{-x}} \tag{1}\]

What is a Logit?
The term logit has different meanings in math and in the TensorFlow library. In TensorFlow it means “Per-label activations, typically a linear output. These activation energies are interpreted as unnormalized

How to create a random variable with a Beta distribution from scratch, using only Uniform random variables
You can use software, like scipy.stats.beta if you want to sample from a Beta distribution. But you can also create a Beta distribution yourself — from scratch. The only thing you need
