Enhanced topology neuroevolution is an algorithm for optimizing the structure of neural networks. Its goal is to improve performance by increasing the topology of the network. This algorithm combines evolutionary algorithms such as genetic algorithms and evolutionary strategies to automatically generate the topology of the neural network and optimize the weights. In addition to optimizing the weights of the network, topology-enhancing neuroevolution also adds new nodes and connections to enhance the topology and functionality of the network. This method has been widely used in fields such as image recognition, speech recognition, natural language processing, and robot control. By increasing the topology of the network, neuroevolution can effectively improve the performance of neural networks, making them more flexible and efficient in complex tasks.
The neuroevolution method of enhanced topology includes the following steps:
1. Initialize the population: randomly generate a set of initial neural network structures, including Nodes and connections.
2. Evaluate adaptability: Use appropriate evaluation functions to evaluate the performance of the neural network structure, such as classification accuracy or regression error.
3. Selection: Select the neural network structure based on adaptability, usually using selection algorithms such as roulette selection or tournament selection.
4. Mutation: Mutation of the selected neural network structure, including adding, deleting and modifying nodes and connections.
5. Crossover: Crossover the selected neural network structures to generate new descendant network structures.
6. Repeat: Repeat steps 2-5 until the preset stopping condition is reached, such as reaching the maximum number of iterations or converging to a certain adaptability threshold.
7. Select the optimal solution: Select the most adaptable neural network structure from the final population as the optimal solution.
8. Test: Test the optimal solution to evaluate its performance on new data.
These steps may be modified or expanded to fit the needs of a particular problem. For example, in step 4, different search spaces can be explored using different mutation operators and probabilities. In step 5, different crossover operators can be used to generate more diversity.
