DNA sequence contains a lot of genetic information, and a variety of phenotypic information of the organism can be obtained by analyzing its single nucleotide polymorphism (SNP). Experiments have shown that 1000-grain weight of rapeseed is positively correlated with its oil yield. In this paper, the 1000-grain weight of rapeseed at maturity is predicted by the genetic data of rapeseed, so as to control the oil yield of rapeseed. When analyzing and processing high-dimensional genetic data, the author proposes a deep learning method—auto-encoder...
