Genetic Algorithms for web page classification

global MATLAB — Thu, 08 Sep 2016 13:38:03 +0000

The genetic algorithm calculated the weights wij for each term. Initially I assigned random real valued weights (between 0 and 1). The GA computed the best weights using the training dataset. Then I classified each test page by computing the cosine similarity of the vector (weights) learned by the GA with the normalized tf vector of the […]

Genetic Algorithms in Dynamic Environments

global MATLAB — Thu, 08 Sep 2016 13:09:50 +0000

Dynamic optimization problems are a kind of optimization problems that involve changes over time. They pose a serious challenge to traditional optimization methods as well as conventional genetic algorithms since the goal is no longer to search for the optimal solution(s) of a fixed problem but to track the moving optimum over time. Dynamic optimization problems have attracted […]

The ability to learn and generalize is fundamental to any learning machine. In particular, generalization behavior is one of the most important topics in any classifier trained non-parametrically (e.g., neural networks). Artificial neural networks (ANNs) use inductive learning to find general concepts from their concrete examples. If there is set of input output to pairs called training set, the network parameters […]

Memetic Algorithm MATLAB code

global MATLAB — Fri, 25 Sep 2015 07:12:52 +0000

The term ‘Memetic Algorithms’ (MAs) was introduced in the late 80s to denote a family of metaheuristics that have as central theme the hybridization of different algorithmic approaches for a given problem. Special emphasis was given to the use of a population-based approach in which a set of cooperating and competing agents were engaged in […]
