gpre2

One of the Data Preproccessing Layers that is mostly not useful for anything not Particle Physics related, since it assumes the Input to be a list of lists of Momentum 4 vectors. Is Outdatet, buggy and only here for consistency

Arguments

• gs: The Number of Particles used, will become the Number of Nodes (Graph size)
• numericC=10000: A Numerical Constant that will be sometimes used to keep things finite

Produced Features

• eta-mean(eta)
• phi-mean(phi)
• ln(pt)
• ln(E)
• -ln(pt/sum(pt))
• -ln(E/sum(E))
• sqrt((eta-mean(eta))**2+(phi-mean(phi))**2)
• iszero (a flag to filter out missing(zero) particles)
