Hi everyones.

I want to use DL for modeling a problem with 6 inputs and one output.

I've used the following layers but I cannot increase the model accuracy not only for unseen samples but also for training samples.

I've check different structures and try to generated a complex model as much as possible to get at least good results in training stages

numHiddenNeuron = 100;

layers = [

featureInputLayer(numFeatures,'Normalization','rescale-symmetric')

fullyConnectedLayer(numHiddenNeuron)

reluLayer('Name','relu')

batchNormalizationLayer

fullyConnectedLayer(numOut)

regressionLayer('Name','regression')];

I would be appreciated it if you could help me.

Regards,

yes，sir，may be add some dropoutLayer in net Layers，such as

numHiddenNeuron = 100;
layers = [
            featureInputLayer(numFeatures,'Normalization','rescale-symmetric')
            fullyConnectedLayer(numHiddenNeuron)
            reluLayer('Name','relu')
            batchNormalizationLayer
            dropoutLayer
            fullyConnectedLayer(numOut)
            regressionLayer('Name','regression')];
% or
layers = [ ...
    sequenceInputLayer(numFeatures)
    lstmLayer(100,'OutputMode','sequence')
    dropoutLayer(0.3)
    lstmLayer(50,'OutputMode','sequence')
    dropoutLayer(0.2)
    fullyConnectedLayer(numOut)
    regressionLayer];

if possible，may be upload your data to analysis

Thank you for your response.

I've check the first one and the results didn't change.

For the 2nd one, my data is not time series and I cannot use the "sequenceInputLayer" as well as "lstmLayer".

Dou you have any other recommendation? Infortunately the resutls are vey bad

I've check it agsin, unfortunately after some iterations (lest than 20), the RMSE does not decrease
