properties at temperatures ranging from 15°C to 30°C for up to 486 distinct hydrocarbons, sourced from the CRC Handbook of Chemistry and Physics and . Up to 17 hydrocarbons were excluded from the NHOC dataset AFProp(1, 452) because they were identified as duplicates due to sharing identical Simplified Molecular Input Line Entry System (SMILES) notation for being isomeric hydrocarbons. Furthermore, certain data points were computed values that displayed significant deviations, as highlighted by Albahri and were excluded. Hence, the dataset for NHOC becomes AFProp(1, 435), which is the final training dataset for NHOC.
