Going from trainNetwork to trainnet
显示 更早的评论
I've attached 3 files(see post below for latest version of these files):
- trainNetworkEXAMPLE - my original trainNetwork implementation
- trainnetEXAMPLE - the trainnet implementation
- example.csv - data file with predictors and targets
The codes for the two examples are identical, the difference is only in the formatting of the input matrices.
trainNetworkEXAMPLE works as expected.
trainnetEXAMPLE works but convergence of the solver is different and solution is poor.
Both codes end with:
Training stopped: Met validation criterion
What am I getting wrong?

Hi @psousa
I too encountered the similar issue when using “trainnet” and “trainNetwork” method.
The workaround that worked in my case was to:
- Use @mse as the loss function instead of "mse" in “trainnet”.
[net,info] = trainnet(XTrain,TTrain,layers,@mse,options);
2. Set 'GradientThreshold' to ‘Inf’ in ‘trainingOptions’ of both the programs.
options = trainingOptions('adam',
...
'GradientThreshold',Inf,
...
);
