  • Design of Electric Power Steering System Identification and Control for Autonomous Vehicles Based on Artificial Neural Network

    Design of Electric Power Steering System Identification and Control for Autonomous Vehicles Based on Artificial Neural Network

    Authors: Rodi Hartono, Hyun Rok Cha, Kyoo Jae Shin

    DOI: 10.1109/ACCESS.2024.3387460

    Abstract

    Electric power steering (EPS) poses significant control challenges in autonomous vehicles due to their inherent complexity and non-linearity. This study explores the application of artificial neural network (ANN) to address these limitations. Two approaches are proposed: 1) an ANN-based identifier utilizing the backpropagation (BP) algorithm to learn the system’s non-linear dynamics, and 2) an ANN-based controller leveraging the Levenberg-Marquardt (LM) algorithm to improve control performance. Our findings demonstrate the efficacy of the proposed ANN-based BP algorithm in EPS system identification achieving over 99.6% accuracy in predicting EPS system dynamics compared to the traditional approach. Additionally, the LM-learned ANN-based controller aiming a faster response and precise reference tracking compared to the traditional controller method. These advancements underscore the potential of employing ANN methodologies to optimize EPS performance in autonomous vehicles. © 2013 IEEE.

    Model Semantic Attention (SemAtt) With Hybrid Learning Separable Neural Network and Long Short-Term Memory to Generate Caption

    Authors: Agus Nursikuwagus, Rinaldi Munir, Masayu L. Khodra, Deshinta Arrova Dewi

    DOI: 10.1109/ACCESS.2024.3481499

    Abstract

    Image captioning is a hot topic that combines a multidiscipline task between computer vision and natural language processing. One of the tasks in the geological field is to make descriptions from the images of geological rocks. The task of a geologist is to write a content description of an image and display it as text that can be used in the future. Interpretation of the object is one of the objectives of the research, which is to traverse the image structures in depth. Shapes, colors, and structures are to be focused on to get the image’s features. The problem faced is how the separable neural network (SNN) and long short-term memory (LSTM) have an impact on the caption that can meet the geologist’s description. SNN is called Visual Attention (VaT), and LSTM is called Semantic Attention (SemAtt) as an architecture of image captioning. The result of the experiment confirms that the accuracy model for captioning gets BLEU-1=0.908 , BLEU-2=0.877 , BLEU-3=0.750 , and BLEU-4=0.510. The evaluation score is compared to those of other evaluators, such as Meteor and RougeL, which get 0.670 and 0.623, respectively. The model confirms that it outperforms the baseline model. Referring to the evaluations, we concluded that the model was able to generate captioned geological rock images that met the geologist’s description. Precision and recall have supported the models in providing the predicted word that is suitable for the image features. © 2013 IEEE.

    DOI: 10.1088/1757-899X/879/1/012129 

    Abstract

    The purpose of this study is to find out how to use Instagram social media as a means of publishing coffee shop photo menus in Bandung. We used a descriptive qualitative research method through literary studies and field observations. From the result, we found out that words and images are a very good combination in the process of sending messages and information. This can be applied to all connoisseurs of photographs, including business people who try to attract consumers’ attention through aesthetic photo techniques. One of them is a coffee shop business that uses aesthetic photo techniques in social media. Therefore, it can be predicted that the use of Instagram is the right tool for publication and increase consumer buying interest. From the research, we can conclude that attractive and aesthetic photographic images can influence how a person perceives or interprets things. Instagram is a social media that is widely used and displays various images to be shared. If many people came to the shop because of a good promotional image on Instagram, it can increase the number of sales and provide more profits. © Published under licence by IOP Publishing Ltd.
