mnrfit takes too long

It takes more than two weeks for a single run of mnrfit.

It just reaches 43/100 iter/iterLim in 'nominalFit' after 1.5 weeks.

I am running it on cpu.

When I pause, it's in the function 'nominalFit'.

n=240000 in my case.

To compare, fitcnet causes less than 1 second. Self-designed MLP with 'trainNetwork' costs 450 seconds.

I am pausing the mnrfit now and want to get the results from the first 43 iters.

Is it supposed to end earlier in some condition?

Hi @Runcong Kuang,

Please refer to this stack exchange question which tackles a similar situation regarding speed. Furthur, I am adding a documentation of mnrfit, which might help you.

Thank you for pointing me to this. I will try the hierarchical mode next time. Whenever you add a documentation on matlab, please let me know. Thanks.
