Research Type Theoretical In this work we theoretically study the trade-off between computational complexity and statistical accuracy in Nyström approximate kernel principal component analysis (KPCA), wherein we show that the Nyström approximate KPCA matches the statistical performance of (non-approximate) KPCA while remaining computationally beneficial.
