Scatter plot of actual data against predicted values of dry weight, intracellular (µg g⁻¹DW), intracellular (µg l⁻¹), extracellular and total yield of paclitaxel, and extracellular paclitaxel portion in Corylus avellana cell cultures using general regression neural network-fruit fly optimization algorithm (GRNN-FOA) models in training subset. The solid line shows fitted simple regression line on scatter points
