I’m fairly new to GeometricFlux.jl and working on trying to implement the Crystal Graph CNN approach by Xie and Grossman. I have the following FeaturedGraph, target pair dataset. I guess what I’m wondering is 1.) How should one do the batching? Does DataLoader(train_data, batchsize=3, shuffle=true, collate=true) make sense? 2.) In the CGCNN paper the edge features tied to a node are concatenated, how should I do that?
Tuple{GraphSignals.FeaturedGraph{GraphSignals.SparseGraph{false, SparseArrays.SparseMatrixCSC{Int64, Int64}, Vector{Int64}, Int64}, GraphSignals.NodeSignal{Matrix{Float64}}, GraphSignals.EdgeSignal{Matrix{Float64}}, GraphSignals.NullGraphSignal, GraphSignals.NullDomain}, Float64}

Any guidance on general tips on setting up and training GNN with GeometricFlux.jl is much appreciatd.
