This paper presents a fault-tolerant middleware for private storage services based on a client-server model. A client-side API split files into redundant chunks, which are encoded/decoded, anonymized, and distributed to different storage locations in parallel by using multistream pipeline. A chunk placement engine on the server-side API receives/delivers chunks from/to the client side API. In this model, the user preserves her files in-house and achieves data availability anytime from anywhere even in site failure scenarios while the organizations preserves the control of their storage resources. The experimental evaluation reveals the middleware can compensate the overhead produced on the client side by taking advantage of multiple cores commonly found in user's devices. The users observe that the middleware produces similar performance to the private and public file hosting systems tested in the evaluation. The organizations observe a significant reduction of work in their servers. In site disaster scenarios, the middleware yields even better performance than fault-tolerant online distributed solutions tested in the evaluation. © 2012 Infonomics Society.

The Electroencephalography discipline studies a type of signals called Electroencephalograms (EEGs), which represent the electrical activity of different parts of the brain. EEGs are composed of a massive number of features that could be used to create an intelligent recognition system. Nevertheless, the high number of available features difficult the correct classification of the signals as most of them do not contain relevant information. The use of Feature Selection (FS) techniques allows the reduction of the number of features by extracting a reduced but powerful feature subset. Afterwards, the problem can be addressed by using both the reduced features along with classification methods. In this sense, this work proposes a comparison of five supervised classifiers to solve an Electroencephalography problem in the context of Motor Imagery-based BCI tasks. The predictive models are evaluated in terms of classification rate and performance (execution time and energy consumption), with the idea of determining which alternative offers the best trade-off among all the objectives. © 2021, Springer Nature Switzerland AG.

Designing a story is widely considered a crafty yet critical task that requires deep specific human knowledge in order to reach a minimum quality and originality. This includes designing at a high level different elements of the film;these high-level elements are called tropes when they become patterns. The present paper proposes and evaluates a methodology to automatically synthesize sets of tropes in a way that they maximize the potential rating of a film that conforms to them. We use machine learning to create a surrogate model that maps film ratings from tropes, trained with the data extracted and processed from huge film databases in Internet, and then we use a genetic algorithm that uses that surrogate model as evaluator to optimize the combination of tropes in a film. In order to evaluate the methodology, we analyse the nature of the tropes and their distributions in existing films, the performance of the models and the quality of the sets of tropes synthesized. The results of this proof of concept show that the methodology works and is able to build sets of tropes that maximize the rating and that these sets are genuine. The work has revealed that the methodology and tools developed are directly suitable for assisting in the plots generation as an authoring tool and, ultimately, for supporting the automatic generation of stories, for example, in massively populated videogames. © 2020 John Wiley & Sons, Ltd

In Community question answering (QA) sites, malicious users may provide deceptive answers to promote their products or services. It is important to identify and filter out these deceptive answers. In this paper, we first solve this problem with the traditional supervised learning methods. Two kinds of features, including textual and contextual features, are investigated for this task. We further propose to exploit the user relationships to identify the deceptive answers, based on the hypothesis that similar users will have similar behaviors to post deceptive or authentic answers. To measure the user similarity, we propose a new user preference graph based on the answer preference expressed by users, such as "helpful" voting and "best answer" selection. The user preference graph is incorporated into traditional supervised learning framework with the graph regularization technique. The experiment results demonstrate that the user preference graph can indeed help improve the performance of deceptive answer prediction. © 2013 Association for Computational Linguistics.

For environmental protection, urban planning, monitoring, and management of the urban ecosystem, mapping urban green spaces is a crucial undertaking. A vital source of information for United Nations Sustainable Development Goal 11.7 could come from urban green space mapping. The standard method of mapping urban green spaces requires field measurements and takes a lot of time. It is also important to update urban green space maps periodically because urban green spaces can change quickly over time due to development. With the advent of high-resolution satellite sensors like Sentinel-1 and Sentinel-2, a large number of remote sensing images may be gathered, providing quick and precise information over urban areas. This work intends to offer a new perspective on how crowd sourced geospatial big data and remote sensing may be combined to enhance the mapping of urban green spaces, including time optimization and accurate information through machine learning and deep learning. For the revitalization of cities, this data will be valuable. Remote sensing imagery data can be classified using machine learning techniques like Support vector machines (SVM), Random forests (RF), and Naive Bayes (NB). In deep learning techniques such as Long Short-Term Memory (LSTM), Convolutional Neural Network (CNN), K Nearest Neighbor (KNN), Generative Adversarial Networks (GAN), and Recurrent Neural Networks (RNN) can be used to classify remote sensing images. © 2023 IEEE.

Adaptation is one of the necessary capabilities of any expert system. In a traditional expert system, the evolving environment is often treated in a static view. And the system accepts the change negatively. Our focus in this paper is to construct an adaptive CBR model which can learn continually through detecting feedbacks from the outside to partially release this. Knowledge base here is improved gradually so to enhance the system's adaptation of solving problems in dynamic environment.

This study analysed work activity in a hospital basement where humans and robots interacted and cooperated on logistics tasks. The robots were deployed to automate parts of courier processes and improve the work environment for the hospital's kitchen staff. Human-robot cooperation was studied through ethnographic fieldwork relating to mobile service robots and hospital kitchen staff. The results highlighted problems arising through the assumption that the gplug and play' service robots could effectively automate work tasks. The analysis revealed the complexity of human-robot interaction in dynamic work settings such as hospitals and identified contradictions between the envisioning and realisation of robots at work, as well as the visible and invisible procedures underpinning human-robot cooperation. Consequently, we emphasise the importance of considering robots as agents of change and draw attention to the new work practices that arise when robots assume the roles of workers in dynamic work settings. © 2021 Owner/Author.

Field tests demonstrated the value of enhancements that enable an advanced nonintrusive load monitoring system to tackle complex monitoring environments. Nonintrusive load monitoring (NILM) can determine the operating schedule of electrical loads in a target system from measurements made at a centralized location, such as the electric utility service entry. In contrast to other systems, NILM reduces sensor costs by using relatively few sensors.

Manual breast cancer diagnosis is time-consuming, error-prone, and requires skilled professionals, while deep learning-based computer-Aided Diagnosis (CAD) systems offer greater performance. Yet existing CAD systems often focus on single imaging modalities, leading to reduced accuracy when applied to different image types. Furthermore, the challenges faced by current deep learning approaches in balancing local feature extraction and global context understanding hinder the development of comprehensive diagnostic tools. To address these issues, we introduce the InceptionNext-Transformer, a novel hybrid deep learning architecture designed for multi-modal breast cancer image analysis. This innovative approach combines Convolutional Neural Networks and Vision Transformers in a unique four-stage design: two initial stages with InceptionNext blocks for multi-scale feature extraction, a third stage employing self-attention to capture global dependencies, and a final stage integrating local and global data for enhanced classification. The study presents a computationally efficient CAD for breast cancer detection applicable to resource-constrained clinical environments. The model exhibited outstanding performance when assessed on seven datasets encompassing histopathology, mammography, and ultrasound imaging modalities. In binary classification using the BreakHis histopathology dataset, it attained 100% accuracy. Using the same dataset, the method achieved 98.25% accuracy for multi-class classification. In the analysis of mammography utilizing the INbreast, MIAS, and DDSM datasets, it achieved an accuracy of 99.97%. On BUSI and BLUID ultrasound datasets, the model attained an accuracy of 92.86%. These findings validate the InceptionNeXt-Transformer’s enhanced capacity for generalization across various imaging modalities. It demonstrates superior diagnostic reliability and computational efficiency, rendering it suitable for resource-limited clinical environments.
