Definition and a brief explanation of the Fire Fly Algorithm The Fire Fly Algorithm (FFA) is a nature-inspired metaheuristic optimization algorithm that is based on the behavior of fireflies. It was first introduced by Xin-She Yang in 2008. Similar to other swarm intelligence algorithms, FFA imitates the collective behavior of fireflies to solve complex optimization problems. Fireflies communicate with each other through the emission of light, which is used to attract mates or find food sources. In FFA, this behavior is translated into a mathematical model where Overview of its applications in optimization problems FFA has been successfully applied to various optimization problems, including but not limited to, engineering design, image processing, data clustering, and economic modeling. It has shown promising results in finding optimal solutions for these problems by efficiently exploring the search space and exploiting the collective intelligence of the swarm. Additionally, FFA's...
The procedure used to carry out the learning process in a neural network is called the optimization algorithm (or optimizer). There are many different optimization algorithms. All have different characteristics and performance in terms of memory requirements, processing speed, and numerical precision. Four major parameters are estimated in the process of developing neural network-based models. The four significant parameters of neural networks include : 1)Activation function from Input to Hidden 2)Activation function from Hidden to Output 3)Number of hidden layers 4)The magnitude of weights of the connections (To know more about the above parameters see my tutorial on Artificial Neural Network ) This article is about the methods utilized to estimate the weights of the connections. The process of estimation of weights is similar to optimization problems. Here the weights are design variables. The transfer function prepared to transfer the information from input to output is the objectiv...
Definition of Particle Swarm Optimization (PSO) Particle Swarm Optimization (PSO) is a population-based stochastic optimization technique inspired by the social behavior of birds flocking or fish schooling. In PSO, a group of candidate solutions, called particles, move around the search space to find the optimal solution through cooperation and communication. Brief history of PSO PSO was first introduced by Kennedy and Eberhart in 1995 as a way to optimize continuous nonlinear functions. Since then, it has been widely used in various fields such as engineering, economics, and biology for solving complex optimization problems. Importance of PSO in optimization problems PSO has proven to be effective in finding solutions to problems with high-dimensional search spaces and non-linear constraints. Its ability to quickly converge to near-optimal solutions makes it a valuable tool for researchers and practitioners facing complex optimization challenges. PSO's ability to efficiently explo...
