Hierarchical sparse representation based Multi-Instance Semi-Supervised Learning with application to image categorization
We propose a hierarchical sparse representation based MISSL algorithm. Instance disambiguation is solved via instance-level sparse representation. Weighted multi-instance kernel based ?1-graph ? 1 - graph is constructed at bag-level. Experiments conducted on image data sets show the effectiveness of our method.
