The world of technology is ever changing and keeping up is sometimes both a grand challenge and a lot of fun. At Orbifold we love to keep up and to delve at the frontier. In this category you will find some of our findings.

What is computational science?

Computational science (also scientific computing or scientific computation (SC)) is a rapidly growing multidisciplinary field that uses advanced computing capabilities to understand and solve complex problems. It is an area of science which spans many disciplines, but at its core it involves the development of models and simulations to understand natural systems. Algorithms (numerical and [...]

Avoid Overfitting Using a Hold-Out Set

‹›Neural Networks Avoid Overfitting Using a Hold-Out Set Use the ValidationSet option to NetTrain to ensure that the trained net does not overfit the input data. This is commonly referred to as a test or hold-out dataset. Create synthetic training data based on a Gaussian curve. In[1]:= data = Table[ x -> Exp[-x^2] + RandomVariate[NormalDistribution[0, [...]
