Although the use of computer color matching can reduce the influence of subjective factors by technicians, matching the color of a natural tooth with a ceramic restoration is still one of the most challenging topics in esthetic prosthodontics. Back propagation neural network (BPNN) has already been introduced into the computer color matching in dentistry, but it has disadvantages such as unstab...

The stability of section coal pillars is one the most important factors affecting rock systems in stope and roadway. This study aimed to develop an artificial intelligence methodology predict evaluate pillar stability. Data from 125 published historical cases were collected build a sample dataset. Meanwhile, mean impact value-genetic algorithm-back propagation neural network (MIV-GA-BP) fusion ...

For the shortcomings of traditional BP neural network, which are easy to fall into local extreme and slow convergence, but the genetic algorithm has the characteristics of global optimization. We combine the two to form an optimized BP neural network algorithm. This method combines the advantages of neural networks and genetic algorithms, which can effectively improve the recognition rate and r...

In the face of more and more faults in coal mine equipment, this paper presents the method of combining genetic algorithm (GA) and BP neural network to predict the failure. According to genetic algorithm has a very slow convergence speed, easy to fall into local optimum, this paper uses chaos and reverse individual learning initialization, followed by the use of differential algorithm to operat...

Breakout is a hazardous accident in continuous casting process. Losses caused by a typical breakout accident can be as high as hundreds of thousands of dollars. Breakout prediction technique is playing an important role in reducing the occurrence of breakout events. Back propagation (BP) neural network based forecast method as an important breakout prediction technique which can be applied in c...

The backpropagation neural network (BPNN) algorithm of artificial intelligence (AI) is utilized to predict A+H shares price for helping investors reduce the risk stock investment. First, genetic (GA) used optimize BPNN, and a model that can multi-day prices established. Then, Principal Component Analysis (PCA) introduced improve GA-BP model, aiming provide practical approach analyzing market ri...

The aim of this study was to predict the bitterness intensity of a drug using an electronic tongue (e-tongue). The model drug of berberine hydrochloride was used to establish a bitterness prediction model (BPM), based on the taste evaluation of bitterness intensity by a taste panel, the data provided by the e-tongue and a genetic algorithm-back-propagation neural network (GA-BP) modeling method...

In this report we want to investigate different methods of Artificial Neural Network optimization. Different local and global methods can be used. Backpropagation is the most common method for optimization. Other methods like genetic algorithm, Tabu search, and simulated annealing can be also used. In this paper we implement GA and BP for ANN.
