this article presents the development and preliminary evaluation of an empathy controlled robot. Such a robot is one step forward towards industry 5.0, as it provides a theoretical framework to enable the performance of the robot to be customized to suit the needs of boththe task as well as the operator. An inventive step is taken through the separation of computational resources based on whether the algorithms are addressing functional or experiential needs. the paper therefore addresses the requirement for new approaches that can be employed in the design of mobile robots to reduce cost, power consumption, and computational burden of the system. We propose that tasks requiring real-time and safety critical control are processed using dedicated on-board computers, whereas functionality dedicated to system optimization, machine learning and customization are handled through use a cloud-based platform. In this paper, key components of the architecture are defined, and the development and preliminary evaluation of an exemplar robot capable of changing its behavior in accordance withthe perceived emotional state of an operator's voice is presented.

Remote sensing is the method of obtaining data of a particular geographic region of interest withthe help of sensors. Often, this data is in form of images, and analyzing such images can give useful information that can help mankind in several ways. In recent years, several methods have been proposed for the same purpose. Most of the successful ones are based on deep learning. Deep learning architectures have a large number of randomly-initialized weights (or parameters) that are trained to extract features from images. Often these weights fail to fully train due to a lack of proper and sufficient training data. To address this issue, transfer learning was introduced. Transfer learning is a technique inspired by humans, which involves initializing deep learning models with weights pretrained on a separate task and fine-tuning them further by training on the desired data. In this work, the same technique is used for classifying remote sensing scenes, with a newly found novel architecture called Res2Net. A single Res2Net block extracts multi-scale features from the input using several receptive layers hierarchically connected to each other with residual-like connections. Although this technique slightly increases the total number of weights, it is capable of capturing relevant and complex features at a granular level. the performance of the proposed approach is evaluated on three remote sensing datasets - UC Merced, Brazilian Coffee Scenes, and EuroSAT dataset and classification accuracies of 98.76%, 93.25%, and 97.50% are achieved, respectively. the method is tested with two fine-tuning techniques on different variations of Res2Net-50. Comparisons with other recently proposed methodologies are shown and confusion matrices are further plotted to better understand the classification potential. the PyTorch code for this work is available at https://***/iamarijit/res2net-remote-sense.

Recommendation systems, which are employed to mitigate the information overload faced by e-commerce users, have succeeded in aiding customers during their online shopping experience. However, to be able to make accurate recommendations, these systems require information about the items for sale and information about users' individual preferences. Making recommendations to new customers, with no prior data in the system, is therefore challenging. this scenario, called the "cold-start problem," hinders the accuracy of recommendations made to a new user. In this paper, we introduce the popular users personalized predictions (PUPP) framework to address cold-starts. In this framework, soft clustering and active learning is used to accurately recommend items to new users. Experimental evaluation shows that the PUPP framework results in high performance and accurate predictions. Further, focusing on frequent, or so-called "popular," users during our active-learning stage clearly benefits the learning process.

In this work we employed a common Recurrent Neural Network (RNN) based sequence model for single document summarization, composed of encoder-extractor hierarchical network architecture. We develop a sentence level selective encoding mechanism to select important feature before extracting sentences, and use a novel reinforcement learning based training algorithm to extend the sequence model. Besides, for single document extractive summarization task, most of researchers only pay attention to the main part of document. We analyze and explore the side information such as the headline and image caption in both CNN and Daily Mail news datasets. Empirical experiment results show the effect that our model outperforms the baseline model, and can be comparable withthe state-of-the-art extractive systems when automatically evaluated in the ROUGE metric. the statistics analysis of the data set verifies our experiment results.

the transition of the power system to more decentralized power plants and intelligent devices in a smart grid leads to a significant rise in complexity. For testing new technologies before their implementation in the field co-simulation is an important approach, which allows to couple diverse simulation models from different domains. In the planning and evaluation of co-simulation scenarios experts from different domains have to collaborate. To assist the stakeholder in this process, we propose to integrate on the one hand semantics of simulation models and exchanged data and on the other hand domain knowledge in the planning, execution, and evaluation of interdisciplinary co-simulation based on ontologies. this approach aims to allow the high-level planning of simulation and the seamless integration of its information to simulation scenario specification, execution and evaluation. thus, our approach intents to improve the usability of large-scale interdisciplinary co-simulation scenarios.

We propose to study the dynamic behavior of indoor temperature and energy consumption in a cold room during demand response periods. Demand response is a method that consists of smoothing demand over time, seeking to reduce or even stop consumption during periods of high demand in order to shift it to periods of lower demand. Such a system can therefore be tackled as the study of a time-series, where each behavioral parameter is a time-varying parameter. Different network topologies are considered, as well as existing approaches for solving multi-step ahead prediction problems. the predictive performance of short-term predictors is also examined with regard to prediction horizon. the performance of the predictors are evaluated using measured data from real scale buildings, showing promising results for the development of accurate prediction tools.

In this study, we present the process of designing machine learning models for the detection of call center agent malpractices. Based on the features extracted from audio recordings of a given telephone conversation, appropriate one-class support vector machine, isolation forest, and multivariate Gaussian models are trained, evaluated and compared in order to determine the best use case. the labeled data used in the experiments was obtained from a real call center and the results obtained indicate that the system is usable in a real-world scenario. the accuracy of used machine learning models are validated by using the F1 score as a metric.

Clustering data based on their spatial and temporal similarity has become a research area with increasing popularity in the field of data mining and data analysis. However, most clustering models for spatio-temporal data introduce additional complexity to the clustering process as well as scalability becomes a significant issue for the analysis. this article proposes a data-driven approach for tracking clusters with changing properties over time and space. the proposed method extracts cluster features based on Gaussian mixture models and tracks their spatial and temporal changes without incorporating them into the clustering process. this approach allows the application of different methods for comparing and tracking similar and changing cluster properties. We provide verification and runtime analysis on a synthetic dataset and experimental evaluation on a climatology dataset of satellite observations demonstrating a performant method to track clusters with changing spatio-temporal features.

Meta-learning use meta-features to formally describe datasets and find possible dependencies of algorithm performance from them. But there is not enough of various datasets to fill a meta-feature space with acceptable density for future algorithm performance prediction. To solve this problem we can use active learning. But it is required ability to generate nontrivial datasets that can help to improve the quality of the meta-learning system. In this paper we experimentally compare several such approaches based on maximize diversity and Bayesian optimization.
