The finish to the Night of Champions main event got me thinking, as a portion of the WWE fan base grumbled over another overbooked and overpopulated conclusion to a premium live event.

Power flow (PF) is one of the most important calculations in power systems. The widely-used PF methods are the Newton-Raphson PF (NRPF) method and the fast-decoupled PF (FDPF) method. In smart grids, ...

A Scientist Says Human Tissue Can Compute Complex Equations Our tissue can serve as a “biophysical reservoir” for data processing, blurring the line between man and machine.

Linear regression is a powerful and long-established statistical tool that is commonly used across applied sciences, economics and many other fields. Linear regression considers the relationship ...

The purpose of this tutorial is to continue our exploration of regression by constructing linear models with two or more explanatory variables. This is an extension of Lesson 9. I will start with a ...

The equation can be written as follows: 1/v^2 * ∂^2y/∂t^2= ∂^2y/∂x^2 In this equation, v is the velocity of a wave, and the other parts describe the displacement of the wave in one direction.

Astrophysicists modeled the solar system’s behavior in two ways. First, they used decades of NASA data to train a neural network. They then used a symbolic regression algorithm to further distill that ...

Through the magic of least sums regression, and with a few simple equations, we can calculate a predictive model that can let us estimate grades far more accurately than by sight alone. Regression ...

The least-squares criterion is a method of measuring the accuracy of a line in depicting the data that was used to generate it. That is, the formula determines the line of best fit.
