An effective approach to visualize multidimensional data — Background Andrews curves, also known as Andrews plot, are a visualization technique used to identify underlying structure in multidimensional data. Similar to principal component analysis and T-distributed stochastic neighbor embedding, Andrews curves reduce multiple features into low dimensional space to display relationships with target variables or classifications. Andrews curves work by…
