However, it is difficult for a machine to understand the feelings of a person and opinion about a topic. Many approaches have been introduced for analyzing sentiment from long text in recent past. In contrast, these approaches fail to address the small length text problem like Twitter data efficiently. Recent advances in the pre-trained contextualized embeddings like Bidirectional Encoder Representations from Transformers (BERT) show far greater accuracy than traditional embeddings. In this paper, we develop a novel architecture to tune the BERT using a Bidirectional Long Short-Term Memory (Bi-LSTM) model. A task-specific layer is incorporated along with the BERT in the proposed model. Our model extracts sentiment from short texts, especially Twitter data. The extensive experiments show the superiority of our model over state-of-the-art models in sentiment analysis task across several gold standard datasets.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125903995","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}

This can provide better local demand-supply balancing, decrease voltage deviations, and improve social welfare. However, economic feasibility of implementation of such a concept greatly depends on regulatory framework, as certain regulatory provisions can either lead to barriers and costs that can undermine the potential benefits of local energy trading, or support implementation of such projects. In this paper, feasibility of local energy trading under different variations of regulatory framework are assessed and implications on market participants and energy balance in distribution grids analyzed. It is shown that regulatory provisions have high influence on potential benefits and implementation of local energy trading in wider scope.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127747043","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}

Ensuring the security of data transmitted, processed and stored across digital channels is a major challenge. One of the frequently used components in cryptographic algorithms to ensure security is substitution-box structures. Random selection-based substitution-box structures have become increasingly important lately, especially because of their advantages to prevent side channel attacks. However, the low nonlinearity value of these designs is a problem. In this study, a dataset consisting of twenty different substitution-box structures have been publicly presented to the researchers. The fact that the proposed dataset has high nonlinearity values will allow it to be used in many practical applications in the future studies. The proposed dataset provides a contribution to the literature as it can be used both as an input dataset for the new post-processing algorithm and as a countermeasure to prevent the success of side-channel analyzes.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"24 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131187133","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}

This paper looks at the task of enhancing images in automatic mode without distortions and loss of information. This work addresses the challenge of improving the effectiveness of image enhancement based on the use of the technique of clipped histogram equalization. To that end, we offer a new technique to image enhancement by gain-limited histogram equalization (GLHE). The proposed GLHE technique is based on a new approach to normalizing the result of clipped histogram equalization. This approach improves the efficiency of improving complex images without the appearance of undesirable distortions and artifacts. The proposed GLHE technique is intended to be used in real-time applications to normalize and improve video content.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132432549","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}

This remains a very challenging task, especially in crowded areas. Due to diverse technical and privacy issues, embedded systems such as smart cameras and smaller drones are becoming ubiquitous. Those complex detection models are not designed for on-edge processing in resource-constrained environments. Therefore, quantization techniques are required, in order to reduce the weights of a model to low-precision and not only effectively compress the model, but also allow to use low bitwidth arithmetic, which in term can be accelerated from specialized hardware. However, using an effective quantization scheme while maintaining accuracy is challenging. In this work we first establish a Quantization-aware training (QAT) and Post-training Quantization (PTQ) baseline for 8-bit uniform quantization to RetinaNet for person detection on the extremely challenging PANDA dataset. Those achieve near lossless performance in terms of accuracy by about 5× speed-up of the CPU inference and 4× model size reduction for 8-bit PTQ quantized model. Further experiments with aggressive quantization scheme in 4- and 2-bit show diverse challenges resulting in severe instabilities. We apply both uniform and non-uniform quantization to overcome those and provide insights and strategies to fully quantize in 4- and 2-bit. Through this process we systematically evaluate the sensibility of individual parts of RetinaNet for quantization in very low precision. Finally, we show the resistance of quantization for limited amount of data.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131627729","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}
