The passage around this formula

…out to roughly an eighth to a ninth of the original computation, for what the paper reports as a small accuracy cost [ 1 ] . MobileNet then added two further dials rather than shipping one fixed shape: a width multiplier α\alpha that uniformly thins the number of channels at every layer, and a resolution multiplier that shrinks the input image, letting a developer choose a point on an accuracy-versus-latency curve instead of accepting whatever a single published checkpoint offered [ 1 ] . That is the detail worth…
