“…The focus of constructive algorithms has primarily been on growing the width of a single hidden layer. Examples of applications with this focus include regression problems [32,33], classification [12,13,20,[34][35][36][37][38][39][40][41][42][43][44][45][46], and image segmentation [47] to name a few (for a list of more applications, see [19]). Conversely, approaches based on cascade correlation have offered a constructive approach that focused on growing network depth instead of width.…”
