Aim of the Study

Convoluted Neural Networks (CNNs) have gained popularity in the recent past as the simulation of human interpretation of photos. The two main fields where simulation is done is the object level- what the photograph aimed to capture- and the scene- the event or location where the photo was taken. Major breakthroughs have been made in the interpretation of image data using multi-layered CNN models that combine information from different sources to increase the reliability of event recognition frameworks. The combination of object and scene level CNN information aims to improve the overall accuracy of detection, increasing the capabilities of event recognition frameworks.

However, the existing literature has been discovered to have several shortcomings, one of which is that it doesnt cover the performances of different individual models with respect to one another. Information on the best possible combination of different CNN models for enhanced performance is also diminished by minimal attention given to this scope of deep architecture. With the insufficient coverage of combining different CNNs, the analysis of the impacts on the fusion scheme performances while shifting from one dataset to another is also an insightful area to be investigated. Understanding the impact of utilizing more than one datasets can open up neural networking to hitherto unexplored areas of discovery.

Purpose statement

The purpose of this research was to evaluate the effectiveness of genetic and particle swarm-based optimization of the fusion of CNN models for event recognition.

Objectives statement

The objectives of the study, which wound up also being the greatest contribution of the study to literature in the field, are stated below:

The report aims to indicate that the combination of Genetic Algorithm and Particle Swarm-based late fusion schemes which combine different deep models performs better than the separate use of models.

Creating a better combination of well-known architectures that are pre-trained on object and places datasets was another aim of the study. Higher performance and ground point of reference for future work was especially targeted.

To achieve the objectives stated above, the study also conducted experiments on three of the most challenging and well-known datasets to determine the optimal weighted combination of different CNN models that leads to a higher performance.


The research process was guided by a number of questions pertinent to the topic of Convoluted Neural Networks. They enabled the researchers to be confined to a set of topical areas that add to the knowledge availability in the field. The main questions covered by the study included:

What is Genetic Algorithm?

What is Particle Swarm Optimization?

How do the two models of deep architecture compare?

How does the object level of CNN interpretation of image data differ from the scene level?

How do different CNN models compare in creating higher performance in the interpretation of image datasets?

How can the models be combined to provide an optimal level of performance?

In seeking the answer to these questions, the objectives of the study, which includes gaining a deeper understanding of convoluted neural networks, were achieved. Another achievement gained from the pursuance of the objectives stated above was that the researchers were able to determine optimal combination of different CNN models, an industrially applicable accomplishment.

As two distinct methods of CNN, Genetic Algorithm (GA) and Particle Swarm Optimization are addressed in different subtopics in every section. This allows the researchers to focus on every critical area of the two before coming up with a strategy for their fusion.

Research ApproachBefore stating the method that was employed in conducting the research, it is imperative that a background to the research topic (CNN) is given. CNN

True experimental research

True experimental research pertains to the forms of experimentation where the subjects of research are treated in a varying manner, with one set of variables being controlled and the other or others being observed to make conclusions on their relationship [1].
