Performance of SamSPECTRAL on synthetic data. (a) This synthetic two dimensional data consists of a normal distribution with 30,000
points, four normal distribution each with 300 points and a uniform background noise
with 4000 points. (b) Around 3000 sample points are picked up by faithful sampling.
These are distributed almost uniformly in the space, therefore, almost all information
about density will be lost if one considers only the samples points. (c) The final
outcome of SamSPECTRAL confirms that the information about density could be retrieved
by properly assigning weights to the edges of the graph. The high density cluster
is shown in red and the surrounding sparser clusters are shown in yellow, light blue,
green and black.
