Research on prediction of oxidation reduction potential based on improved ABC and LSSVM algorithm

Oxidation reduction potential plays an important role in the control and optimization of the biological oxidation pretreatment process of gold, a new LSSVM parameter optimization method based on improved antificial bee colony is proposed. Improved ABC algorithm is based on the standard ABC algorithm, and Euclidean distance is introduced to the improved ABC algorithm to identify the valid neighborhood, so that onlooked bees can use search strategy which is different from employed bees. Using improved ABC algorithm to optimize factors, then the optimal solution can be assigned to LSSVM to predict. Taking real data of a gold mine in Xinjiang to simulate, the result show that: LSSVM based on the improved ABC algorithm can improve the prediction accuracy of the model, and the method makes the model have a better prediction.
