  • In the real world, it is common that different experts have different opinions on the same problem due to their different experience. [...] Key Method We formulate Comdi as a quadratic optimization problem and propose an efficient alternating strategy to find the solution. Besides learning a globally consistent metric, Comdi provides an elegant way to share knowledge across multiple experts without sharing the underlying data, which lowers the risk of disclosing private data. Our experiments on several…Expand Abstract
