# Neural Network Optimization (Part 2) — Evolutionary Strategies | by Mandar Angchekar | Medium. # Neural Network Optimization (Part 2) — Evolutionary Strategies. ## Neural Network Optimization (Part 1) — Differential Evolution Algorithm ### Explained and Implemented in Python. This post talks about Evolutionary Strategies (ES), evaluating its potential in training neural networks against the benchmark of traditional backpropagation methods. Central to this exploration was the adaptation of ES to fine-tune neural networks, with a particular focus on optimizing mutation rates for enhanced performance. The code block below illustrates key operations in an evolutionary strategy for neural network optimization: recombining genetic material from two parents to create offspring, mutating offspring by adding Gaussian noise, and assessing fitness by evaluating the negative loss on training data. The plot displays the trend in average fitness of a neural network optimized using Evolutionary Strategies (ES) over a logarithmic scale of generations.

# Neuroevolution: Evolving Neural Network with Genetic Algorithms. Neuroevolution is a subfield of artificial intelligence (AI) and machine learning that combines evolutionary algorithms(like Genetic Algorithm) with neural networks. The primary idea behind neuroevolution is to evolve neural network architectures and/or their weights to solve problems or perform specific tasks. Before getting into neuroevolution in detail, let us first overview the concepts of neural networks and genetic algorithm. By marrying biological evolution principles with computational models, neuroevolution introduces a paradigm shift in the way neural networks learn, adapt, and solve complex problems. At its essence, neuroevolution harmonizes two powerful concepts — neural networks and genetic algorithms. Neuroevolution involves the application of genetic algorithms to enhance neural networks. They involve creating a population of neural networks, evaluating their performance on a given task, selecting the best-performing networks to serve as parents, and applying genetic operations (crossover and mutation) to produce a new generation of networks.
