%description
Neural network has potential in forestry modelling. This package is
designed to create and assess Artificial Intelligence based Neural
Networks with varying architectures for prediction of volume of forest
trees using two input features: height and diameter at breast height, as
they are the key factors in predicting volume, therefore development and
validation of efficient volume prediction neural network model is
necessary. This package has been developed using the algorithm of Tabassum
et al. (2022) <doi:10.18805/ag.D-5555>.
