Improve the level set algorithm by Lagrangian particle enhanced replanting algorithm and increase the reduced segmentation accuracy brought about by the algorithm for uneven image pixel for medical CT image. Based on Literature [4], the combination of Lagrangian particle enhanced replanting algorithm and level set algorithm is adopted, the convergence of velocity field for singular point is promoted through increase of velocity vector and unit normal vector and the medical CT image segmentation method of hybrid level set(LPRLS) based on Lagrangian particle enhanced replanting algorithm is proposed in the Thesis. Calculate the Lagrangian labeled particle before calculating the formula of horizontal set to rebuild the embedded interface in order to improve the mass conservation property of level set algorithm;improve the convergence of velocity field for singular point and topological change point through increasing velocity vector and unit normal vector in order to handle the singularity of interface and complicated geometric correlation. The simulation results of algorithm indicate that the performance of the proposed algorithm is greatly improved compared with the original algorithm. It can be concluded from the simulation results that the existing insufficiency is the proportion of error identification of the algorithm.

Fruit fly optimization algorithm is a new swarm intelligent algorithm proposed in recent years and has been concerned for its few parameters and high computational efficiency. However, the application of the algorithm is limited for unstable optimization capability. To solve that question, an improved fruit fly optimization algorithm is proposed in this paper. Some factors affecting the performance of the algorithm are improved. The improved algorithm are proved by function optimization and applied to the analog circuit fault diagnosis.

In the process of software testing, correlated defects raise researchers' attention worldwide. Some potential defects are hard to be detected in the test. To address these potential defects, this paper adopts an error propagation model to describe the process of defect evolution and applies fault injection method to introduce known seed-defects. Subsequently, seed-defects are activated and related potential defects are induced through test case design. This method employs intelligent algorithms to constantly design test cases to cover paths of seed-defects and paths of propagation. As a result, more undetected and correlated defects can be detected in paths of propagation.

To meet the shape quality requirements of "Dead flat" rectangular section of electrical steel in the cold rolling process, the transverse thickness difference (TTD) prediction model of 6-high tandem cold rolling mills (TCMs) based on genetic algorithm, particle swarm optimization, and support vector regression (GA-PSO-SVR) is proposed. The TTD prediction model uses 5000 coils of data obtained from a cold rolling line. The GA-PSO-SVR model is obtained by the GA-PSO hybrid algorithm to search and obtain the optimal parameter of the SVR to improve the prediction model accuracy. The results reveal that using multiple evaluation indicators the GA-PSO-SVR model has preferably adaptability and higher accuracy. Meanwhile, the relative importance of input variables is calculated based on the GA-PSO-SVR model, which indicates that the shape control methods in stands 1-5 have the most important influence on the TTD. The TTD prediction model is continuously applied to 1420 mm 6-high TCMs;the results show that the rate of the TTD less than 7 mu m increased from 29.6% to 63.85%.

Drilling parameters optimization has consistently generated research interest over the years because of the costsaving benefits associated to improve drilling efficiency. However, several physics-based and data-driven models have been developed for drilling parameters optimization, and the majority of the data-driven models are based on regression methods. Obtaining highly accurate and optimized drilling parameters with rapid as well as costeffective simulation runs is difficult to achieve. To accurately and rapidly predict drilling parameters, a multiobjective optimization model was proposed in this study. In the proposed model, the rate of penetration (ROP), unit drilling cost (UDC), and mechanical specific energy (MSE) were considered as the objective functions, while the weight on bit (WOB) and rotations per minute (RPM) were chosen as the optimization variables. Meanwhile, a method for ROP prediction based on improved back propagation neural network (BP) is also presented. Field data presented in this study indicate that when drilling is free of drilling complications, this multi-objective optimization model could optimize WOB and RPM with higher ROP and lower MSE, and UDC.

Because of the improvement of the current neural network depth learning algorithm, some basic artificial intelligence technology has developed rapidly. In the financial sector, artificial intelligence can greatly optimize the process of a series of existing financial transaction, which can be applied and served to customers at the front end to achieve a variety of financial transactions and financial analysis decisions. Based on this, the research and implementation of financial decision model based on artificial intelligence were studied in this paper. The impact of artificial intelligence on the financial industry was introduced first. Technical problems and solutions, theoretical support and key technologies were introduced. Finally, the specific process of financial decision model based on Agent artificial intelligence was introduced in detail. The test results show that the financial decision model based on artificial intelligence can be used for risk prevention and control, which makes our financial services more personalized and intelligent, so that the financial risk control ability is more powerful.
