变分贝叶斯推断的量子退火
Quantum Annealing for Variational Bayes Inference
摘要:
研究了一种基于量子退火的变分贝叶斯(QAVB)推理的确定性退火算法,该算法可以看作是变分贝叶斯模拟退火(SAVB)推理的扩展. QAVB和SAVB一样容易实现。实验结果表明,QAVB发现一个更好的局部最优比SAVB的变分自由能在潜在的狄利克雷分配(LDA)。
英文摘要:
This paper presents studies on a deterministic annealing algorithm based on quantum annealing for variational Bayes (QAVB) inference, which can be seen as an extension of the simulated annealing for variational Bayes (SAVB) inference. QAVB is as easy as SAVB to implement. Experiments revealed QAVB finds a better local optimum than SAVB in terms of the variational free energy in latent Dirichlet allocation (LDA).
