Posterior distributions of the Hubble constant H0 derived from DESI DR2 BAO and reconstructed CC+SN Ia data, based on GPR (green), ANN (orange), and LSTM (blue). Vertical bands show the 1σ regions of SH0ES (D. Brout et al. 2022), TRGB (W. L. Freedman et al. 2020), and Planck (Planck Collaboration et al. 2020).
