Evidence-based health care (EBHC) is an important practice of medicine which provides systematic scientific evidence to answer clinical questions. Epistemonikos is one of the most important online systems in the field. Currently, many tasks within this system require a large amount of manual effort, which could be improved by leveraging humanin- the-loop machine learning techniques. In this article we propose a system called EpistAid, which combines machine learning, relevance feedback and an interactive user interface to support Epistemonikos users' on EBHC information filtering tasks.

The impressive evolution of neural networks and deep learning techniques during the last few years has offered new incomparable routes to solve many complex problems. Moreover, the fact that neural networks are structured and supervised has made it possible to perform automatic parameter tuning that guarantees convergence to the best expressive model for the problem assessed. In this work, we investigated the use of recurrent neural networks (RNNs) to solve the sequential sparse recovery problem through unfolding the iterative soft thresholding algorithm (ISTA) into a stacked RNN. Specifically, we examined the performance of the unsupervised iterative algorithm and the supervised network for a purely compressive sampling reconstruction problem of time-frequency representations. Our results demonstrated that the trained stacked neural network outperforms the iterative algorithm in the quality of the reconstructed data and points to several future directions to improve the performance.

New technologies are changing the way we learn and teach. Emerging technologies such as social semantic web, cloud computing, and the growing popularity of mobile devices, embedded devices and adaptive context-aware technologies are leading to a paradigm shift in the way educational services are provided. Through technologies and approaches such as ubiquitous and adaptive learning, learning becomes personalized, flexible, and suitable to meet diverse and rapidly changing technologies, environments and learner needs, while opening unprecedented possibilities for education. The aim of the "intelligent Interfaces for Ubiquitous and Smart learning" workshop has been to bring together researchers from industry and academia to address the challenges of the intelligent user interfaces and smart learning fields, discuss new ideas and present their research to the scientific community in order to enhance the methodologies and techniques for intelligentlearning environments for the 21st century.

In a variety of use-cases, deriving information on user's fatigue is an important step for content adaptation. In this work, we investigate which eye-tracking related measures can predict the error rate (as a proxy of subject's fatigue) during a visual experiment. data was collected during a 40 minutes campimetric task, where the user has to detect visual stimuli (i.e., dots) of different contrast. We found that eye-tracking measures can be used to train a machine learning model to predict the error rate of a user with an average correlation of 0.72±0.17. The results show that this method can be used to measure the user's response quality. Copyright is held by the owner/author(s).

Cybersecurity, especially intrusion detection, is becoming increasingly critical in our daily life. The intrusion detection systems (IDS) have been widely used to prevent disclosure of personal information and detect potentially suspicious attacks. Although many machine learning algorithms have been broadly applied to enhance the performance of IDS, low detection rate and high false alarm rate are still two critical problems. A collaborative and robust intrusion detection model using a novel optimal weight strategy based on Genetic Algorithm (GA) for ensemble classifier is proposed in this paper. Since network data stream can be divided into three categories according to network protocols, detectors are applied in the network protocol separately. All of the detectors can work collaboratively and efficiently. In the proposed model, GA is used to optimize the weight of each base classifier of ensemble classifier. In order to improve features quality, Principal Component Analysis (PCA) is used for dimension reduction and attribute extraction. The NSL-KDD datasets is used to test the effectiveness of the collaborative intrusion detection model. Experimental results show that the proposed model has a higher accuracy and better generalized performance than others in this field.

data-driven models, and maturating data-treatment tools, now allow for automation in a wide range of domains. The data-rich domain that is NC machining presents a strong potential for automation, in this regard, and the smart factory calls for knowledge capitalisation in manufacturing. The field of machining saw numerous data formats, and is still led by heterogeneous sources. To exploit this massive amount of data, capitalisation of information from those sources is compulsory. Such system should allow aggregation of different sources and formats, and accommodate for information about diverse elements regarding manufacturing Parts, tools, machines... In this paper, automated process planning generation methods are reviewed. The localisation and formalisation of data in manufacturing documents is considered, and emphasis is made on linking trajectories and features, to define strategies. Attempts to use machine learning techniques in manufacturing are reviewed, and the lack thereof in manufacturing knowledge retrieval is underlined. Then, a framework is proposed to realise knowledge retrieval from legacy programs, and several locks and improvement possibilities are identified.

After many decades of research, the presence of intelligent user interfaces is unquestionable in any modern operating room (OR). For the first time, we aim to bring proactive intelligent systems into microsurgery OR. The first step towards an intelligent surgical microscope is to design an activity-aware microscope. In this paper, we present a novel system that we have built to record both eyes and instruments movements of surgeons while operating with a surgical microscope. We present a case study in micro-neurosurgery to show how the system monitors the surgeon's activities. We achieved about 1 mm accuracy for gaze and instrument tracking. Now real-time ecologically valid data can be used to design, for example, a self-adjustable microscope. Copyright held by the owner/author(s).
