BiconvexIncrementalDataGenerator

public BiconvexIncrementalDataGenerator(int nusers,
                                        int nfeatures,
                                        int ntasks,
                                        double sparcity,
                                        double xsparcity,
                                        boolean indw,
                                        boolean indu,
                                        int seed,
                                        double noise)

Parameters:

nusers - The number of users (U is users x tasks, X is features x users)

nfeatures - The number of features (W is features x tasks)

ntasks - The number of tasks (Y is 1 x tasks)

sparcity - The chance that a row of U or W is zeros

xsparcity - The chance that a column of U or W is zeros

indw - If true, there is a column of W per task

indu - If true, there is a column of U per task

seed - If greater than or equal to zero, the rng backing this generator is seeded

noise - The random noise added to Y has random values for each Y ranging from -noise to noise
