Efficient Stochastic Simulation Algorithm for Chemically Reacting Systems Based on Support Vector Regression

The stochastic simulation algorithm (SSA) accurately depicts spatially homogeneous well-stirred chemically reacting systems with small populations of chemical species and properly represents noise, but it is often abandoned when modeling larger systems because of its computational complexity.In this work,a twin support vector regression based stochastic simulations algorithm (TS₃A) is proposed by combining the twin support vector regression and SSA,the former is a well-known robust regression method in machine learning.Numeri-cal results indicate that this proposed algorithm can be applied to a wide range of chemically reacting systems and obtain significant improvements on effciency and accuracy with fewer simulating runs over the existing methods.
