AAAI & CVPR 2016: Preconditioned Stochastic Gradient Langevin Dynamics (pSGLD)
Hi,
I was trying to run test_FNN_mnist.m but I got the following error:
" Undefined function or variable 'environmentVariables'. "
Can you tell me to fix it?
Thanks
In SGLD_RMSprop.m
the noise is scaled by opts.N
which is set to Ntrain in DNN experiments:
https://github.com/ChunyuanLI/pSGLD/blob/master/pSGLD_DNN/algorithms/SGLD_RMSprop.m#L51
Why is this the case? In the paper (https://arxiv.org/pdf/1512.07666v1.pdf) there is no such scaling.
I also checked SGLD_Adagrad.m
and there is no scaling by Ntrain for the noise.
Hi Chunyuan,
Thanks for sharing. I found that in the 2-D simulation experiment the learning rate(injected Gaussian noise level) is kept constant, which doesn't satisfy the assumption 1 in your AAAI '16 paper. While in previous works e.g. Welling 2011, I found a polynomial decay scheme is applied. Will this be a problem?
