NOISE dataset
The NOISE dataset is a semi-synthetic dataset constructed from the matrix A∗, where the data is generated from y = A∗x + ζ, where ζ is the noise. -
NEG dataset
The NEG dataset is a semi-synthetic dataset constructed from the matrix A∗, where the entries of A∗ are i.i.d. samples from the uniform distribution on [−0.5, 0.5). -
CTM dataset
The CTM dataset is a semi-synthetic dataset constructed from the matrix X, whose columns are drawn from the logistic normal prior in the correlated topic model. -
DIR dataset
The DIR dataset is a semi-synthetic dataset constructed from the matrix X, whose columns are from a Dirichlet distribution with parameters (0.05, 0.05,..., 0.05).
