23-limit tuning and intervals | Equal temperaments

A12 is a non-octave-repeating scale or musical tuning featuring twelve steps to the tritave. As twelve steps to the octave is based on a triad of harmonics 4:5:6 (root, major third, perfect fifth), A12 is based on a triad of harmonics 4:7:10 (root, harmonic seventh, and compound major third). Discovered by Heinz Bohlen between 1972 and 1973, it was named "A12" by Enrique Moreno. Bohlen considered this scale less logically consistent than the Bohlen–Pierce scale, which has thirteen steps in the twelfth. (Wikipedia).

A Gentle Introduction To Math Behind Neural Networks and Deep Learning (nested composite function)

In this video, we explain the basic mathematics behind neural networks and deep learning through a simple classification example. We start by defining a threshold logic unit or TLU, also known as neuron. We then discuss the concept of a weight sum or linear combination followed by applying
