Property estimation is the technology for calculating molecular properties from several molecular information.
Group contribution methods are the methods of molecular property estimation from the information of groups which construct the molecule.
The concept of a neural network (NN) is to develop a simple mathematical model of the human brain. A neural network is expressed as the network model that consists of neurons and weights which connect each neuron. This network is the function that derives the result corresponding to the teaching process from input data.
We have produced high quality original property estimation schemes using the Neural Network algorithm.
