On the other hand, the available frequency band is limited, and the issue of frequency band exhaustion becomes more serious. Visible Light Communication (VLC) is attracting attention as a solution to these problems. VLC is a technology that transmits signals by means of flicker or obscuration of visible light. The advantage of this technology is that it does not impose restrictions on the frequency band because lighting can be used as communication. Another advantage is that it is safe for the human body and does not impact other wireless devices [1] . In a VLC system based on orthogonal frequency division multiplexing (OFDM), Intensity Modulation - Direct Detection (IM/DD) is applied as a cost effective design [2] . The intensity modulated optical signal is transmitted, which is directly detected by the photodiode on the receiving side. Although the system is quite simple, it is susceptible to noise [1] . Therefore, it is important to improve the performance in a low SNR situation.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130448750","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}

Therefore, this paper integrates many water quality sensors, long-range (LoRa) wireless communication technology, and open source cloud services to develop a LoRa based Water Quality Monitoring System (LWMS).

Early detection of DR plays an important role in preventing blindness. Use of deep learning is a long term solution to screen, diagnose and monitor patients within primary health centers. Attention based networks (Transformers), Convolutional neural networks (CNN) and multi-layered perceptrons (MPLs) are the current state-of-the-art architectures for addressing computer vision based problem statements. In this paper, we evaluate these three different architectures for the detection of DR. Model convegence time (training time), accuracy, model size are few of the metrics that have been used for this evaluation. State-of-the-art pre-trained models belonging to each of these architectures have been chosen for these experiments. The models include EfficientNet, ResNet, Swin-Transformer, Vision-Transformer (ViT) and MLP-Mixer. These models have been trained using Kaggle dataset, which contains more than 3600 annotated images with a resolution of 2416*1736. For fair comparisons, no augmentation techniques have been used to improve the performance. Results of the experiments indicate that the models based on Transformer based architecture are the most accurate and also have comparative model-convergence times compared to CNN and MLP architectures. Among all the state-of-the-art pre-trained models Swin-Transformer yields the best accuracy of 86.4% on test dataset and it takes around 12 minutes for training the model on a Tesla K80 GPU.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131146236","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}

In particular for the detection of lane lines the system should able to perform faster and accurately locate the position of the lane lines. The majority of the existing work in this task relies on the frame-based processing in which the whole image is used as a feature. In addition for the case of high-resolution images the computational time is very significant and not feasible for practical applications in particular for embedded system. To overcome this problems, in this work a novel lane line detection system is proposed. The proposed approach utilizes the slice of a frame image as a feature and applies deep learning to detect and segment the lane line. Experimental results show that the proposed system can efficiently handle lane line detection by 60 times faster than the former schemes with superior accuracy.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132821500","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 aim of this paper is to develop novel deep learning based one-shot learning framework which can achieve state-of-the-art results on new classes (one-shot classes) which have only one image each during the training phase. Adding these new one-shot classes, should not degrade the performance of the model on pre-trained classes. Multi-layer transformation function has been proposed in this paper for one-shot learning, where activations of a class are converted to their corresponding parameters. The model is pre-trained on large-scale base classes and the model adapts to new classes with zero training. Experiments were conducted on opensource datasets like MiniImageNet and Pascal-VOC using Nvidia K80 GPU. The model achieves an accuracy of 93.14% for large scale base classes and 64.69% for one-shot classes which is more than 3% better than the current state-of-the-art models.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132055145","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}
