There are times when the framework's Random() class may not be considered random enough, given that it is based on a psuedo-random number generator. The framework's Crypto classes do, however, provide something more robust in the form of RNGCryptoServiceProvider. The following code samples demonstr...

Acknowledgement This example is adapted from this article on type inference What is type Inference? Type Inference is the mechanism that allows the compiler to deduce what types are used and where. This mechanism is based on an algorithm often called “Hindley-Milner” or “HM”. See below some of th...

The machine has to automatically determine the ideal behavior to maximize its performance. For example: Using reinforcement learning you can also make a computer program that can complete a Mario level (MarI/O - Machine Learning for Video Games).

Many modern Image Processing algorithms use patches are their basic element to work on. For instance one could denoise patches (See BM3D Algorithm). Yet when building the image form the processed patches we have many results for the same pixel. One way to deal with it is taking the average (Empir...
