What is a hyperparameter? A model hyperparameter is a configuration external to the model and whose value cannot be estimated from data. They are often used in processes to help estimate model parameters and are specified by the practitioner. They can often be set using heuristics, and they are often tuned for a given predictive […]


What is a heuristic? A heuristic is a technique to solve a problem faster than classic methods or find an approximate solution when classic methods cannot. It is a kind of a shortcut as we often trade one of completeness, optimality, precision, or accuracy for speed. A heuristic looks at search algorithms. Each branching step […]
