Can someone show me how to build an example enseble deep network like is shown in figure 2 of attached zip?

See attached or via link https://www.mdpi.com/2076-3417/10/4/1504/pdf

Can you share your progress?

lgraph_1.zip

The issue was that I made the attached network I made in Deep Learning Toolbox directly referencing "Layers"

[net0,info0] = trainNetwork(inputTrain,targetTrain,lgraph_1.Layers,options);

This give errror shown below.

I should have ran it...

[net0,info0] = trainNetwork(inputTrain,targetTrain,lgraph_1,options);

This works without errors.

Kind Regards

Emil

Hi Emil,

Regarding the networks: RNNs, GRU and LSTMs are definitely supported.

Custom RNNs are more tricky to implement, you could use custom layers and custom training loops methods:

Regarding the ensemble method: the easiest way to ensemble deep learning models is to train different networks individually and then combine the predictions of all networks using one of the post-hoc ensemble approaches (e.g. average predictions or majority voting). To give you some ideas:

Thanks Paola

For example, the problem I have is building the layers with the deep learning toolbox.

When I try to train the network it get an error.
