A Steiner deltoid maintains constant area across all boundary points of an ellipse.
Criteria for sharksfin and deltoid singularities from plane to plane, with applications.
Abstract: Deltoid map connects complex dynamics and algebra.
We introduce a new sub-linear space sketch---the Weight-Median Sketch---for learning compressed linear classifiers over data streams while supporting the efficient recovery of large-magnitude weights in the model. This enables memory-limited execution of several statistical analyses over streams, including online featu…
