Disentanglement architecture featuring multi-discriminators. The architecture operates as follows: spectra x and stellar parameters y are concatenated as input. The encoder then maps this concatenated input, x ⊕ y, to the latent space z, with the aim of disentangling y from z. Subsequently, the decoder’s task is to reconstruct x using z ⊕ y as input. In parallel, discriminators receive z as input and endeavour to predict the astrophysical parameters within a discretised space y^d.
