I thought this too- working with Shapley values is quite intuitive, and the article does an excellent job of this- but how do we derive the synergy values to plug-in in the first place? How do we know that Liam + Emma’s synergy = 0?
Liam alone makes $10
Emma alone makes $20
Liam + Emma make $30
$30 - ($10 + $20) = $0, their synergy.
In general: the synergy is how much more or less the coalition gets than each member’s individual contribution plus all subset synergies.
