Hammersley-clifford定理证明
WebHammersley-Clifford’s theorem - Proof Line of proof due to Besag (1974), who clarified the original “circuitous” proof by Hammersley & Clifford!Assume the positivity condition … Web注:Hammersley Clifford Theorem理论认为,马尔科夫随机场和Gibbs分布是一致的。 也就是说: 1)Gibbs分布一定满足由node separation导致的条件独立性. 2)马尔科夫随机场的概率分布一定可以表示成最大团们上的非负函数乘积形式. 2. 马尔科夫随机场(MRF)
