Namely, we add two dense layers at the end of the model, the first one has 1024 neurons with ReLu activation and the last one has 10 neurons with Softmax activation, and then we use it as a base classification model on Cifar10 dataset.

The challenges of ERP implementation have caused a high rate of failure based on the stories of numerous organizations that have deployed the solution. ERP brings together data from all business functions, giving the entire organization a broader perspective. They can control the whole company by monitoring purchasing, requests, ordering, finished products in stock and other business-critical information needed for management. Successfully deployed enterprise resource planning systems can deliver significant strategic, operational, and informational benefits to the organizations involved, saving resources and time.","PeriodicalId":345017,"journal":{"name":"2022 8th International Conference on Optimization and Applications (ICOA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114358029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Widely known for their ability to increase the performance of antenna arrays, beamforming techniques are expected to play a major role in 5G systems. For reaching low peaks side lobe level (PSLL) in antenna design, it is necessary to optimize the amplitude weights of a linear antenna array. By optimizing the amplitude weight of the array's elements, a method for achieving a low side lobe level is explored. Utilized is a binary genetic algorithm with single point crossover and roulette wheel selection. The minimum SLL (minimize side lobe levels) for the radiation pattern is the cost function that is employed. The convergence of the optimization algorithm is demonstrated by simulations under Matlab environment and, its utility is shown in getting a desired antenna beam pattern, BGA converges before 50 generations in all the considered cases, We have seen that the level of the secondary lobes reaches nearly −30 dB for all the networks. We also note that the more the size of the antenna array increases, the more the number of iterations necessary for convergence is high.","PeriodicalId":345017,"journal":{"name":"2022 8th International Conference on Optimization and Applications (ICOA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125046273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Localizing and region segmentation is of particular interest, although typical approaches rely on complex networks and/or human interactions. Therefore, various complex networks suffer from suboptimal segmentation due to inaccurate feature extraction. This paper introduces a Multi-Gated Nested Network (MGN-net) that provides precise segmentation performance by capturing relevant contextual information via a channel gating mechanism. Results utilize challenging biomedical image databases, featuring MRI Brain and Chest X-ray images, are presented. The results show that the MGN-net approach subjectively and objectively performs favorably compared to multiple state-of-the-art methods, such as the U2-net and U-net networks.","PeriodicalId":345017,"journal":{"name":"2022 8th International Conference on Optimization and Applications (ICOA)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121980861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several regularization or approximation techniques like Fisher-Burmeister's method, interior-point methods (IPMs) approaches, or smoothing methods already exist. All the corresponding methods solve a sequence of nonlinear systems of equations and depend on parameters that are difficult to drive to zero. The main novelty of our approach is to consider the smoothing parameters as variables that converge by themselves to zero. We do not need any complicated updating strategy, and then obtain nonparametric algorithms. We prove some global and local convergence results and present several numerical experiments, comparisons, that show the efficiency of our approach.","PeriodicalId":345017,"journal":{"name":"2022 8th International Conference on Optimization and Applications (ICOA)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124115236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several biometric modalities can be used and each one presents a particular interest, according to the targeted application. Within the framework of our study paper, we have realized a facial recognition system based on the EfficientDet model following the architecture of a deep neural network. The facial recognition process is divided into several steps, namely: face detection in each image, face normalization, facial feature extraction, classification and decision. The training and evaluation of the system were done on the database: Casia-web face. As Casia-web Face is unlabelled, we have developed an algorithm using the open source deep learning framework Mxnet to convert the images into binary format, reduce their size and give each image an identifier. Finally, the optimization of the system has been done using Root Mean Squared Propagation (RMSProp) and the Shard shuffling optimizers.","PeriodicalId":345017,"journal":{"name":"2022 8th International Conference on Optimization and Applications (ICOA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126281597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contribution was the fruit of the construction of four statistical models (OLS model, Backward regression model, forward stepwise regression, and both ways stepwise regression) aiming to identify the most decisive variables affecting the attractiveness of the population. For this purpose, while aiming to be more exhaustive in the analysis, a diversified battery of socio-economic, spatial, and geographical indicators has been mobilized to conduct structural modeling. The econometrics findings show that the phenomenon of residential attractiveness is quite complex and is subject to the influence of several variables where each has its own effect. However, we have demonstrated that the supply of employment and the development of industrial activity remain the most important factors influencing the territorial attractiveness of small cities in Morocco ($mathrm{p} < 0.001$).","PeriodicalId":345017,"journal":{"name":"2022 8th International Conference on Optimization and Applications (ICOA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129181154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
