WebPrimary producers (usually plants and other photosynthesizers) are the gateway for energy to enter food webs. Productivity is the rate at which energy is added to the bodies of a group of organisms (such as primary producers) in the form of biomass. Gross productivity is the overall rate of energy capture. Net productivity is lower, adjusted ... WebFor example, DNN models with multiple hidden layers estimated soybean biomass with the estimation accuracy exceeding R 2 of 0.72 (Maimaitijiang et al., 2024). A DNN model with four hidden layers performed well in wheat biomass estimation, achieving an R 2 value close to 0.80 (Moghimi et al., 2024). However, the performance of DNN algorithms in ...
