Dimension Reduction on Measures of Impulsivity
… technique known as Local Linear Embedding (LLE). LLE is an analysis of dimension reduction for nonlinear, high dimensional data. By computing neighborhood preserving embeddings, LLE aims to map newly constructed coordinates into a global coordinate structure of a lower dimension. Past …

A Fuzzy/Neural Approach to Cost Prediction with Small Data Sets
… cost estimate uses the locally linear embedding (LLE) algorithm for a nonlinear reduction method that is then put through an adaptive network based fuzzy inference system (ANFIS). The second method is a two stage system that uses various ANFIS with either single or multiple inputs for a cost …

Search for R-parity violating supersymmetry in multilepton final states with the DŸ detector
… followed by R-parity violating decays via an LLE-operator with one dominant coupling lambda_122. An LLE-operator couples two weak isospin doublet and one singlet (s)lepton fields and thus violates lepton number conservation. The data, collected with the D0 detector at the Fermilab …
