PPT-MCMC in practice

Start collecting samples after the Markov chain has mixed How do you know if a chain has mixed or not In general you can never proof a chain has mixed But in may cases you can show that it has NOT If you fail to do so using several different methods you probably convinced yourself that it has mixed. cmuedu Chong Wang chongwcsprincetonedu Eric P Xing School of Computer Science Carnegie Mellon University epxingcscmuedu Abstract Communication costs resulting from synchro nization requirements during learning can greatly slow down many parallel mach .
