There has been a tremendous increase in the costs of caring for older adults owing to the fact that societies are aging around around the world. This has led to a decrease in the number of caregivers who are able to assist. Investigative studies indicate that older adults require social as well as physical support for their well-being which prompted researchers to use social and cognitive robots and advanced human machine interaction devices. However, most of these studies have shortcomings when it comes to providing means of a natural interaction with the machine. With speech being the most natural way for human communication and the huge developments in the Internet of Things and smart homes, equipping a robotic system with powerful natural speech interaction capabilities to maintain a conversation with an elderly while being linked to other smart home devices shows a promising direction. This paper describes a scalable and expandable system with main goal of designing a natural speech-enabled system for older adults that is capable of linking to multiple active agents with minimal integration efforts. The system makes use of the power of commercially available digital assistant systems, integrated with an intelligent conversational agent, robotics, and smart wearables. The main advantage of the system is that it could provide a portion of the population, namely older adults and the disabled, the flexibility of interacting naturally with powerful social robots in smart home environments, hence providing them with much needed independence.

Background and Objective: Sleep staging plays a vital role in sleep research because sometimes sleep recording errors may cause severe problems like misinterpretations of the changes in characteristics of the sleep stages, medication errors, and, finally, errors in the diagnosis process. Because of these errors in recordings and analysis, the sleep behavior and automated sleep staging system are adopted by different researchers with different methodologies. This study identifies specific challenges with the existing studies and highlights certain points that support the improvement of automated sleep staging-based polysomnography signals. Methods: This work provides a comprehensive review of an automated sleep staging system, which was contributed by the different researchers in the recent research developments using Electroencephalogram, Electrocardiogram, Electromyogram, and combinations of these signals. Results: Our review in this research area shows that single-model and multimodal signals are used for sleep staging, and also we have observed some great points from the existing methodologies: (1) It has been noticed that 30-s length of the epoch of EEG signals may not be sufficient to extract enough information for discriminating the sleep patterns but in the other hand that a 10-s and 15-s length epoch is well suitable for sleep staging, (2) due to similar characteristics on N1 and REM sleep stages, most of the traditional classification models misclassified N1 sleep stages as REM stage, which alternatively degrades the sleep stagging performance, (3) consideration of heterogeneous form signal fusions can give the improvement results on sleep staging, and (4) applying deeplearning based models, combinedly to significant PSG signals can lead to more robust automatic sleep staging results. Conclusions: The review mentioned above points simultaneously improves automated sleep staging by polysomnography signals. These points can help to focus our research work fro

In data mining, various techniques are applied on large sets of data. These large sets of data are known as big data. For extraction and retrieval of desired information or pattern from big amount of data and quantity of knowledge, we tend to use huge data processing. To maintain working of "big data," various logics are used. Today, because of many online applications, product price is highly dynamic and current price can be compared by the customers by using different applications. In our work, we have used modified K-means clustering method and divided online data. Dataset is divided into 10 clusters for analysis. In the last section, the conclusion based on I/O time and computational time is given.

Instead of the Kalman-type filters requiring strict assumption on noise distributions, the extended set membership filter (ESMF) only assumes unknown but bounded (UBB) noises, therefore is more practical and applicable for the active modeling of robotic ureteroscope. However, the ESMF calculation needs the ellipsoid analysis that usually suffers from numerical instability, especially during the real-time processing of sensory measurements, and may further result in the divergence of the whole control system. In this paper, we propose the singular value decomposition for ESMF to handle this problem. The ESMF is firstly introduced as a preknowledge. Then, a singular value decomposition-based extended set membership filtering algorithm (SVD-ESMF) is constructed based on the sequential processing technique. Finally, we verify the performance of the proposed algorithm combined with the active modeling method on a self-built robotic flexible ureteroscope platform. Compared with the normal ESMF algorithm, the SVD-ESMF successfully eliminates the influence of unstable points and guarantees the confidence of the estimated bounds.

Recently, due to the expansion of TV or smart phone, the frequency of exposing media has increased. Also, the way of interacting with the media is diversifying by life stages or life balance. In such situations, people get much information about products and services on media. Therefore, it is important to select the best media for advertisement. In this study, we analyze the characteristics of exposing media using media exposure data. First, we performed Non-negative Matrix Factorization (NMF) to extract pattern of exposing media. Second, we used random forest to analyze the characteristics of the exposing media pattern. From our result, we discussed how to advertise on TV and website.

This paper majorly concerns the classification of handwritten numerals of Devanagari Script. The major contributions in this paper are 1) Development of a dataset for handwritten numerals similar to MNIST dataset, 2) analysis of pattern Recognitions tools based on NN and Convolution Neural Network, 3) Detailed discussion on the results by calculating the Precision, recall and F-measure values and compared with the other dataset available online. The present dataset includes 4,282 handwritten numerals of Devanagari which are collected from people of different ages. In the methodology developed in this paper, all the numerals are extracted from the image. After pre-processing, the images are resized to 30X30 which are later converted to vectors. These vectors with labels are the inputs for the classifiers. ANN classifier is designed by using PRToo1 and Deep Learning network is designed to make comparison with ANN. Data for training and testing splits into different ratios 80:20, 70:30, 60:40 and 50:50. This research has achieved accuracy of more than 95%. The results of the dataset generated are compared with the dataset available online. (C) 2020 The Authors. Published by Elsevier B.V.
