  1. (geometry) A superellipse: a curve in two dimensions of a certain type, a generalization of the ellipse.

      The hyperellipse is defined by (x/a)n + (y/b)n = 1 with b ≤ a, where n is the shape parameter and a and b are the axes along the x and y axes, respectively.
  2. (geometry) Specifically, a superellipse with an exponent (shape parameter) greater than that of the ellipse (two).
  3. (geometry) A multi-dimensional manifold of a certain type, a generalization of the ellipse and ellipsoid.

      This algorithm extends the model of RNS by incorporating multiple hypershape (hypersphere, hyperrectangle, or hyperellipse) detector representation in the unit hypercube [0, 1]n (Balachandran et al., 2007).
