In questo articolo dimostriamo come la struttura di una rete autoencoder può essere utilizzata per produrre l’outpunt di una analisi che riducail computational effort.
Archetypal Analysis as an autoencoder
Archetypal Analysis (AA) is a data approximation method which approximates data points by convex (positive coefficients with unitary sum) combination of prototypes, denoted as 'archetypes'. 'Archetypes' themselves are a convex combination of the original data points.
AA was introduced as a dimensional reduction method in [1, 2] with more interpretable results when compared to Principal Component Analysis (PCA). The original comparison study had the goal of designing facemasks for the Swiss Army, starting from a dataset consisting of 6 head dimensions for 200 soldiers.
