Diabetic Retinopathy (DR) is one of the major causes of visual impairment and blindness across the world. It is usually found in patients who suffer from diabetes for a long period. Major focus of this work is to derive optimal representation of retinal images that further helps to improve the performance of DR recognition models. In order to extract optimal representation, features extracted from multiple pre-trained ConvNet models are blended using proposed multi-modal fusion module. These final representations are used to train a Deep Neural Network (DNN) used for DR identification and severity level prediction. As each ConvNet extract different features, fusing them using 1-D pooling, and cross pooling lead to better representation than using features extracted from a single ConvNet. Experimental studies on benchmark Kaggle APTOS 2019 contest dataset reveals that the model trained on proposed blended feature representations is superior to the existing methods. In addition, we notice that cross average pooling based fusion of features from Xception and VGG16 is the most appropriate for DR recognition. With the proposed model, we achieve an accuracy of 97.41%, and a kappa statistic of 94.82 for DR identification and an accuracy of 81.7% and a kappa statistic of 71.1% for severity level prediction. Another interesting observation is that, DNN with dropout at input layer converges faster when trained using blended features, than compared to the same model trained using uni-modal deep *** Codes 68T10, 62H30 Copyright © 2020, The Authors.

We propose a semi-tensor product attention network model as a visual question answering tool for complex interaction over image features. Proposed model performs matrix multiplication of two arbitrary dimensions, which is used to overcome possible dimensional limitations and improve recognition flexibility. In used block-wise operation we preserve spatial and temporal information but reduce the number of parameters by using low-rank pooling scheme. applied BERT pre-train model is tuned to recognize question features. The proposed model is evaluated on the VQA2.0 dataset. Research results show that our model has good accuracy and easy reconfiguration for future research.

In this paper, we show preliminary results on the quality assessment of crowdworker output based on the movements of the mouse and the eyes while the task is performed. We assume that the mouse and the eyes stop longer if the quality is lower due to the lack of knowledge, or confidence, etc. Because the mouse- and eye-stopping duration follows lognormal distribution, we estimate its parameters (mean and standard deviation) to evaluate the quality. Results of preliminary experiments with 10 participants show that the parameters of correct outputs are different from those of incorrect ones. As compared to the task duration, which is often used as a feature for assessment, we have found that the mouse-and the eyestopping duration is advantageous and complementary for the assessment.

It is now a noticeable trend in High Performance Computing that the systems are becoming more and more heterogeneous. Compute nodes with a host CPU are being equipped with accelerators, the latter being a GPU or FPGA cards or both. In many cases at the heart of scientific applications running on such systems are iterative linear solvers. In this work we present a software package which includes an FPGA implementation of the Conjugate Gradient algorithm using a particular problem of the Dirac-Wilson operator as encountered in numerical simulations of Quantum Chromodynamics. The software is written in OpenCL and C++ and is optimized for maximal performance. Our framework allows for a simple implementation of other linear operators, while keeping the data transport mechanisms unaltered. Hence, our software can serve as a backbone for many applications which are expected to gain a significant boost factor on FPGA accelerators. As such systems are expected to become more and more widespread, the need for highly performant FPGA implementations of the Conjugate Gradient algorithm and its variants will certainly increase and the porting investment can be greatly facilitated by the attached code.

This paper presents a study on the impact of the antenna cavity on the in-body propagation and ultra wideband wireless body area networks (UWB-WBAN) radio channel characteristics between the capsule endoscope and the on-body antenna. The study is conducted with CST Studio Suite simulations and one of its anatomical voxel models. A simplified capsule model and two different on-body antennas designed for low-band UWB in-body communications are used in this study. The first antenna has a smaller cavity while the second antenna has a larger cavity. The radio channel characteristics between a capsule endoscope model and an on-body antenna are evaluated with the cavity and without the cavity in frequency and time domains. Furthermore, 2D power flow representations are studied to get insight how the presence and absence of the cavity changes the signal propagation within the tissues. It is found that with the antenna having a smaller cavity, the cavity impact depends on the on-body antenna location respect to the abdominal muscle layers. Instead, the antenna having a larger cavity enables to capture multipath components from the wider area resulting in stronger signal regardless where the antenna is located.

5G-enabled drones have potential applications in a variety of both military and civilian settings (e.g., monitoring and tracking of individuals in demonstrations and/or enforcing of social / physical distancing during pandemics such as COVID-19). Such applications generally involve the collection and dissemination of (massive) data from the drones to remote data centres for storage and analysis, for example via 5G networks. Consequently, there are security and privacy considerations underpinning 5G-enabled drone communications. We posit the potential of leveraging blockchain to facilitate privacy preservation, and therefore in this article we will review existing blockchain-based solutions after introducing the architecture for 5G-enabled drone communications and blockchain. We will also review existing legislation and data privacy regulations that need to be considered in the design of blockchain-based solutions, as well as identifying potential challenges and open issues which will hopefully inform future research agenda.

Many are calling for concrete mechanisms of oversight for health research involving artificial intelligence (AI). In response, institutional review boards (IRBs) are being turned to as a familiar model of governance. Here, we examine the IRB model as a form of ethics oversight for health research that uses AI. We consider the model's origins, analyze the challenges IRBs are facing in the contexts of both industry and academia, and offer concrete recommendations for how these committees might be adapted in order to provide an effective mechanism of oversight for health-related AI research. © 2021 by The Hastings Center.

Distributed databases (DDB) help store and process data, which grows due to the current demand for voice, video and data;that require efficient processes for their optimization. The objective is to analyze the efficient processes available for the optimization of a distributed database, to determine the impact on data processing. We used the deductive method for the analysis of the information of the reviewed articles and the exploratory research;to provide a reference of the current situation in the optimization of a database. It turned out a table with the summaries of the optimization problems and the proposed solutions for the processes;in this table a score of zero to five was made based on the information provided by the researchers of the reference and table 1;considering the higher qualification that allows to improve the efficient processes for the optimization in a distributed database. It was concluded that each researcher aims to present an alternative to improve response times through proposals such as: Algorithms, models or optimization methods;this information allows an evaluation to determine which proposals could be more efficient in a distributed database. © 2018 IEEE.
