Using Neural Networks to Build Robust Hourly Models
February 14, 2018
Our first brown bag seminar of the year is entitled, “Using Neural Networks to Build Robust Hourly Models.” Neural networks are flexible functional forms that learn about nonlinear relationships from the data. These models can be used to identify nonlinearities and variable interactions and to construct x variables that embody these relationships. Learn more about these variables and how they can be used in regression models that have rich relationships that are also simple and robust.

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
