Two Equal Size Clusters

Two gaussians with equal size and bandwidth, from "How to Use t-SNE Effectively".

Usage

two_clusters_data(n, dim = 50)

Arguments

n

Number of points per gaussian.

dim

Dimension of the gaussians. You may pass a vector of length 2 to create clusters of different dimensionalities, with the smaller cluster having zeros in the extra dimensions.

Value

Data frame with coordinates in the X1, X2 ... Xdim columns, and color in the color column.

Details

Creates a dataset consisting of two symmetric gaussian distributions with equal number of points and standard deviation 1, separated by a distance of 10 units. Points are colored depending on which cluster they belong to.

Examples

df <- two_clusters_data(n = 50, dim = 2)
# two clusters with 10 members each, first 10 sampled from a 3D gaussian,
# second 10 are sampled from a 4D gaussian
df <- two_clusters_data(n = 10, dim = c(3, 4))
