The original assignment set forth instructed students to implement a feedforward artificial neural network (ANN) in a relatively low level language or framework. Although higher level scripting languages such as Python and Lua have wrapped heavily optimized libraries that perform the same functions, the goal of this assignment is to truly understand the theoretical underpinnings of feedforward neural networks by writing the routines from scratch (almost).
