Neural networks calibrate 2D and 3D Dainotti relations on the Platinum GRB sample via ANN-driven MCMC to produce a model-independent Hubble diagram with reduced scatter.
DESI DR2 BAO and Pantheon+/Union3 SN Ia datasets are mutually consistent at 1-2 sigma using crossing statistics, supporting a reconstruction suggestive of evolving dark energy at low redshift.
Reconstruction of EFT background functions from cosmic chronometer Hubble data allows model-independent tests of dark energy evolution in scalar-tensor theories.
Extended analysis of DESI DR2 data confirms robust evidence for dynamical dark energy with phantom crossing preference, stable under parametric and non-parametric modeling.
