How to calculate auto and cross correlation coefficients of time series data set?

Auto and Cross Correlation Coefficient is used for approximation of the auto and cross correlation of the two part of same data series and two different data series. Their magnitude depicts the way they are related to each other..Such concepts are included in the basics of statistics.However the knowledge of these two metrics are important before a model is to be developed for prediction of real time case study.

You can find the tutorial by going to my slide-share account.

Particle Swarm Optimization with out code

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...

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...
