Study on the neural network of lanthanide's quantitative structure-property relationship

The various influemce factors to the physicochemical properties of lanthanide are studied in this paper and the physicochemical properties of nine kinds of lanthanide are associated too using lanthanide foundation state value L,electronegativity 4f,electronic arrangement periodic factors q and ionic radius as the parameters and using the BP neural network based on L-M optimization algorithm.The obtained results are satisfactory and this method is better than the ordinary linear regress method and suitable to the study on completed quantitative structure-property relationship.
