I find that the data structure of LayerGraph and DAGNetwork in neural network toolbox have the same contents. So, is there any difference between them?

A LayerGraph is used to specifically describe layout of the layers of a DAG network. It has methods to play around with the layer structure such as addLayers, connectLayers. removeLayers etc. A DAGNetwork is the neural network model as a whole and not just the layers. Its' methods involve playing around with the model like predict, classify, activations etc. In short, you'd be using layerGraph to specify a DAGNetwork but there is much more to it like training it etc.

LayerGraphs and Layers contain the network architecture (for DAGs and Series networks, respectively). These objects are then passed to trainNetwork for validation and training. LayerGraphs and Layers may have weights or not, but they cannot be used for prediction. One can only call prediction on DAGNetwork and SeriesNetwork objects. These objects contain the validated and trained network.
From R2018b to convert a LayerGraph and Layers object with weights and all the needed parameters to a DAGNetwork/SeriesNetwork one can call assembleNetwork, example:
net = assembleNetwork(layers);

One can not use assembleNetwork(layerGraph). Is there a way to validate and initializa a layerGraph without training?

the pair of LayerGraph and DAGnetwork remsembles with one of Layer and SeriesNetwork(in my mind)

Then how can we convert a LayerGraph we trained to seriesNetwork to use it in classifications?

I have the same situtation too. How can we change the trained layergraph to a seriesnetwork or dagnetwork?
