About Visual Backpropagation
Visual Backpropagation is an open source(Apache 2.0 license), functional programming specification of backpropagation that yields a visual and transparent implementation within spreadsheets. This backpropagation implementation exploits array worksheet formulas, manual calculation, and has a sequential order of computation similar to the processing of a systolic array. The implementation uses no hidden macros nor user-defined functions; there are no loops, assignment statements, or links to any procedural programs written in conventional languages.
