We investigate the impact of the initial density and tidal shear fields on the formation of haloes over the mass range $11.4 \\leq \\log(M/M_{\\odot}) \\leq 13.4$. The algorithm is trained on an N-body simulation to infer the final mass of the halo to which each dark matter particle will later belong. We then quantify the difference in the predictive accuracy between machine learning models using a metric based on the Kullback-Leibler divergence.","authors_text":"Andrew Pontzen, Hiranya V.
