WebbAn informative training set is necessary for ensuring the robust performance of the classification of very-high-resolution remote sensing (VHRRS) images, but labeling work is often difficult, expensive, and time-consuming. This makes active learning (AL) an important part of an image analysis framework. AL aims to efficiently build a … WebbNext, one replaces the random oracle by a \crypto-graphic hash function" (such as SHA), where all parties (including the adversary) have a succinct description of this function. Thus, one obtains an implementation of the ideal system in a \real-world" where random oracles do not exist. The random-oracle methodology has been used quite ...
