Kernel Embeddings and the Separation of Measure Phenomenon
Researchers have demonstrated that kernel covariance embeddings can perfectly separate distinct continuous probability distributions. This mathematical proof establishes that distinguishing between two identical continuous probability measures is equivalent to distinguishing between two centered Gaussian measures in a reproducing kernel Hilbert space. The findings suggest that this "separation of measure phenomenon" could enhance the design of efficient inference tools and explains the effectiveness of kernel methods. AI
