On-Demand Augmentation for Long-Tail Data Through Subset- and Topic-Driven Sparsity Identification Framework
Abstract Large-scale, multi-dimensional mixed datasets are characterized by the pervasive "long-tail distribution." This phenomenon results in data sparsity in subspaces defined by multi-dimensional attribute combinations. This sparsity severely hinders data-driven analysis and insights. Existing…
