![Comparison between the StarBRUNet predictions and APOGEE DR17 catalogue on the test set. The left-hand panel shows the results from the APOGEE DR17 catalogue, and the right-hand panel shows the estimated results from StarGRUNet. The colours indicate the [Fe/H] abundances. The solid line, the dashed line, and the dotted line respectively indicate three MIST stellar isochrones with stellar ages of 7 Gyr.](https://oup.silverchair-cdn.com/oup/backfile/Content_public/Journal/mnras/521/4/10.1093_mnras_stad831/1/stad831fig4.jpeg?Expires=1749317247&Signature=F0Edz0fUelhV14ms0Lq7StI6vHD4VKlgzIxBT1Fu46vCNTH~f1DzBYisa3lSjUpSAHnc8fKbqQ7RvqMv1PWAjuhZzoE95L8Ik8~LOzIa0m00gGo0flYpMH4ugGDaNDpgM4QpvF00EJiUdGBqH8lIIVNljqKrvchcc0~BrksTB9kQfdF6AmmaKEavsKWyVNhACqlgSY6zEZrFvG2JZmDGAtE0aX7PO0Suj0mMZWG8-3g7xaI6NMW-9W3L5PAYy8BSZev9Vmdv8QGGSJ45vy77TsFzY92KBgCSPGK3~8atH-1LBySQpbxUBAFH5YDaeUo-Bm67uOn02FkX7hcyJj056A__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
