We have implemented four LDL algorithms, namely IIS-LLD, BFGS-LLD, CPNN, LDSVR, aa. To help you start working with LDL, we provide three demos (See iisllddemo.m, bfgsllddemo.m, cpnndemo.m, ldsvrdemo.m) in this package. The readme.txt can help you start working with the package.Download LDL Matlab Package
Currently v1.2 [Adding AA-BP, AA-kNN, PT-Bayes and PT-SVM algorithm, updated 2016-5-1]
We have collected 15 real-world LDL data sets.Download Data Sets
