![]() Mintzberg himself, who considerably advanced our ideas on management practice, noted that he always considered Simon to be the most influential and important contemporary author in terms of organizational theory (1990, p. Herbert Simon is unique in our discipline in terms of the far-reaching impact which his work has had on management and the understanding of managerial decision making, especially when his further work with James March is considered. Keywords: Artificial intelligence, Diabetic Retinopathy, Attention Mechanism, AlexNet The experiment shows that our proposed method can provide results that can detect the pathological areas and effectively classify DR. The highest accuracy in this study is up to 91% and used the attention mechanism algorithm and AlexNet architecture. We obtained 344 fundus images from the Kaggle dataset, which contains normal, mild, moderate, severe and proliferative DR. This study also compared AlexNet architecture with and without attention mechanism. The attention mechanism algorithm focuses on detecting the pathological area in the fundus images, and AlexNet is used to classify DR into five levels based on the pathological area. AI uses deep learning, such the attention mechanism algorithm and AlexNet architecture. This study implemented AI for detecting and classifying DR. This study aimed to implement artificial intelligence (AI) to resolve the lack of current methods. ![]() Currently, doctors require a long time and professional skills to detect DR. The ophthalmologist examines signs through fundus images, such microaneurysm, exudates and neovascularisation and determines the suitable treatment for patient based on the condition. Diabetes seriously affects the blood vessels in the retina, a disease called diabetic retinopathy (DR). The number of people around the world who have diabetes is about 422 million. Thus the application meets the requirements for making the program, which is readable and valid. After going through the equivalence partitioning testing process, in general this system produces a total percentage of 100% on the success of the item test by experts in the testing process of the 25 items tested. Decision making used uses the certainty factor method based on certainty factors. ![]() With the help of artificial intelligence, it is expected that the system can assist in the decision making of guitar technicians in the process of making guitar repair decisions based on the symptoms that occur. Therefore, it is necessary to develop a system that can act as a tutor in the maintenance and repair of guitars by utilizing artificial intelligence embedded in the system. ![]() The easiest thing is to bring a broken guitar to the experts, but when there are not many guitar service experts or a long enough distance to reach it, then guitar repairs need to be done immediately. Damage to the guitar is something normal because of its intense use so it needs proper handling in the repair process. As a metronome, the guitar must be well standardized on the quality of each part so that sound that comes in line with the user's expectations in this case is the guitarist. Guitar is a popular musical instrument in the world and is a metronome for every use in various music events and its correlation.
