Axis-Aligned Decomposition of Linear Projections.

Project description


Axis-Aligned Decomposition of Linear Projections


pip install axisproj

From source:

pip install -e . or python


from axisproj import LPPObjective, optiomal

objective = LPPObjective(knn=12,sigma=0.3)
lp, ap = optimal(X, objective)

Three linear projection objectives are defined in axisproj.objective

  • LDEObjective
  • LPPObjective
  • PCAObjective

optimal() also accepts an optional histogram function. The default value is generated using the precision_recall.histogram functor.


This package is a rewrite of the LLNL code described in

"Exploring High-Dimensional Structure via Axis-Aligned Decomposition of Linear Projections Linear Axis-Aligned", J. J. Thiagarajan, S. Liu, K. N. Ramamurthy and P.-T. Bremer, EuroVis 2018
