Since the k-nearest neighbor (k-NN) classification is computationally demanding in terms of time and memory, approximate nearest neighbor (ANN) algorithms that utilize dimensionality reduction and hashing are gathering interest. Dimensionality reduction saves memory usage for storing training patterns and hashing techniques significantly reduce the computation required for distance calculation. Several...
Increasing global atmospheric CO 2 concentrations are expected to influence crop production. To investigate the effect on rice (Oryza sativa L.), plants were grown under ambient CO 2 (AMB) or free-air CO 2 -enrichment (FACE) at CO 2 concentrations ranged from 275 to 365μmolmol −1 above AMB. We supplied 13 CO 2 to the plants at different growth...
