Description: The package includes the MATLAB code of the multi-instance learning algorithms miVLAD and miFV, which are efficient and scalable MIL algorithms. miVLAD/miFV maps the original MIL bags into a new feature vector representation, which can obtain bag-level information, and meanwhile lead to excellent performances even with linear classifiers. In consequence, thanks to the low computational cost in the mapping step and the scalability of linear classifiers, miVLAD/miFV can handle large scale MIL data efficiently and effectively. A Readme file and some data files are included in the package.
