about 2: sgd and als are point estimators that find the "best" model parameters, it is reasonable to use the parameters of the last iteration. MCMC is a sampling method that finds many probable model parameters. Just like it is not a good idea to use one of the decision trees out of a random forest, taking one of the MCMC models won't give a good prediction. Instead, the MCMC models produced by each "iteration" should be used collectively.
about 1: Can you give some more details what you mean by "the result just like 0,0,3333,1..."? Is this the AUC or several predictions of the CTR model?

oh, thank you so much for your reply, about 2 it is the out file of the prediction for TASK_CLASSIFICATION , i may find the reason that i have a lot feature which value is too large such
as several thousand result in cache_e for pre_y is too large if init_stdev is large.
thank you again for your reply.
