摘要

The present invention relates to a toxicity prediction model capable of simply and accurately predicting acute oral toxicity of a chemical material based on a quantitative structure-toxicity relationship by using a linear and non-linear learning method. According to the present invention, the toxicity prediction model comprises: a step 1) of collecting and refining compound data having acute oral toxicity and an active value; a step 2) of collecting and calculating a calculable descriptor from a molecular structure of the compound data; a step 3) of dividing the collected and rectified compound data into a training set and an external verification set; a step 4) of performing a precedence filtration operation on the calculable descriptor; a step 5) of selecting a descriptor suitable for an acute oral toxicity prediction; a step 6) of increasing the descriptor, accumulating each optimized machine learning models and results, generating a combination model for reducing an error generated in each model through a model obtained by combining at least two of calculated models, and determining a final model through an inter-comparison; a step 7) of setting an applicable range for a reliability estimation in the final model and applying the applicable range; and a step 8) of determining reliability and suitability of the final model.;COPYRIGHT KIPO 2016
