TurboQuant: Redefining AI efficiency with extreme compression

I did not understand what polarQuant is.

Is is something like pattern based compression where the algorithm finds repeating patterns and creates an index of those common symbols or numbers?

TurboQuant Animated: Watch Vector Quantization Happen

Interactive 2D and 3D animations showing every step of TurboQuant: normalize, rotate, quantize, reconstruct. Add your own points and see the compression error in real time.

I like the visualization, but I don’t understand the grid quantization. If every point is on the unit circle aren’t all the center grid cords unused?
i think grid can be a surface of the unit sphere
