Humans continuously learn and demonstrate intelligent behaviour. Various mechanisms are used to collect information, analyze the same and produce output. If the output is not satisfactory, corrections are made next time to produce a better output. Artificial Neural Networks (ANN) are computational network structures that are based on the above concept and the structure of brain cells called neurons. ANNs are composed of artificial neurons which work like the brain neurons, each performing a very simple task but when connected as a network, are able to learn gradually as humans enabling machine intelligence. Genetic Algorithm (GA) is based on the concepts of evolution where better solutions are derived by using many iterations or generations of trial and errors. The process starts with a random set of solutions which gradually gets refined by creating new solutions from the old ones until no further significant improvements can be achieved. These machine learning techniques are showing promising results for certain problem domains where all the data are not known in advance, and where machines need to continuously learn to adapt to the changing stimuli or situation. The brain-like ANNs have been used to model human cognition, perception, and memory. Recently these techniques are also being applied to train and refine the knowledge of robots which are used in many critical applications such as speech, text, sensor data analytics and computer vision. You will learn different ANNs and GAs in this course, models of ANNs for human cognition, and how these techniques are used in problem solving such as classification, clustering, optimization and data reduction. You will need to develop software programs (using any programming language such as Python, C, C++, Matlab, Java) to implement ANN models, train and test them. By the end of the course, you will know the significant ANNs and GA techniques, have experience in writing software programs that implement some of these algorithms to solve practical problems, and get an idea of the ongoing research in this area in various application domains.
