在 MATLAB Online 中打开

There are zillions of my posts in both the NEWSGROUP and ANSWERS that use the criterion

       Ntrneq >= Nw      %( number of training equations >= number of unknown weights )

to obtain an upper bound, Hub, on the number of hidden nodes that should be used without early stopping and/or regularization .

Search both using

greg narx Hub

or

greg narxnet Hub

Hope this helps.

Thank you for formally accepting my answer
