Ground: A Data Context Service.

Abstract: Ground is an open-source data context service, a system to manage all the information that informs the use of data. Data usage has changed both philosophically and practically in the last decade, creating an opportunity for new data context services to foster further innovation. In this paper we frame the challenges of managing data context with basic ABCs: Applications, Behavior, and Change. We provide motivation and design guidelines, present our initial design of a common metamodel and API, and explore the current state of the storage solutions that could serve the needs of a data context service. Along the way we highlight opportunities for new research and engineering solutions. 1. FROM CRISIS TO OPPORTUNITY Traditional database management systems were developed in an era of risk-averse design. The technology itself was expensive, as was the on-site cost of managing it. Expertise was scarce and concentrated in a handful of computing and consulting firms. Two conservative design patterns emerged that lasted many decades. First, the accepted best practices for deploying databases revolved around tight control of schemas and data ingest in support of general-purpose accounting and compliance use cases. Typical advice from data warehousing leaders held that “There is no point in bringing data . . . into the data warehouse environment without integrating it” [17]. Second, the data management systems designed for these users were often built by a single vendor and deployed as a monolithic stack. A traditional DBMS included a consistent storage engine, a dataflow engine, a language compiler and optimizer, a runtime scheduler, a metadata catalog, and facilities for data ingest and queueing—all designed to work closely together. As computing and data have become orders of magnitude more efficient, changes have emerged for both of these patterns. Usage is changing profoundly, as expertise and control shifts from the central accountancy of an IT department to the domain expertise of “business units” tasked with extracting value from data [14]. The changes in economics and usage brought on the “three Vs” of Big Data: Volume, Velocity and Variety. Resulting best practices focus on open-ended schema-on-use data “lakes” and agile development, This article is published under a Creative Commons Attribution License (http://creativecommons.org/licenses/by/3.0/), which permits distribution and reproduction in any medium as well allowing derivative works, provided that you attribute the original work to the author(s) and CIDR 2017. CIDR ’17 January 8-11, 2017, Chaminade, CA, USA in support of exploratory analytics and innovative application intelligence [28]. Second, while many pieces of systems software that have emerged in this space are familiar, the overriding architecture is profoundly different. In today’s leading open source data management stacks, nearly all of the components of a traditional DBMS are explicitly independent and interchangeable. This architectural decoupling is a critical and under-appreciated aspect of the Big Data movement, enabling more rapid innovation and specialization. 1.1 Crisis: Big Metadata An unfortunate consequence of the disaggregated nature of contemporary data systems is the lack of a standard mechanism to assemble a collective understanding of the origin, scope, and usage of the data they manage. In the absence of a better solution to this pressing need, the Hive Metastore is sometimes used, but it only serves simple relational schemas—a dead end for representing a Variety of data. As a result, data lake projects typically lack even the most rudimentary information about the data they contain or how it is being used. For emerging Big Data customers and vendors, this Big Metadata problem is hitting a crisis point. Two significant classes of end-user problems follow directly from the absence of shared metadata services. The first is poor productivity. Analysts are often unable to discover what data exists, much less how it has been previously used by peers. Valuable data is left unused and human effort is routinely duplicated—particularly in a schema-on-use world with raw data that requires preparation. “Tribal knowledge” is a common description for how organizations manage this productivity problem. This is clearly not a systematic solution, and scales very poorly as organizations grow. The second problem stemming from the absence of a system to track metadata is governance risk. Data management necessarily entails tracking or controlling who accesses data, what they do with it, where they put it, and how it gets consumed downstream. In the absence of a standard place to store metadata and answer these questions, it is impossible to enforce policies and/or audit behavior. As a result, many administrators marginalize their Big Data stack as a playpen for non-critical data, and thereby inhibit both the adoption and the potential of new technologies. In our experiences deploying and managing systems in production, we have seen the need for a common service layer to support the capture, publishing and sharing of metadata information in a flexible way. The effort in this paper began by addressing that need. 1.2 Opportunity: Data Context The lack of metadata services in the Big Data stack can be viewed as an opportunity: a clean slate to rethink how we track and leverage modern usage of data. Storage economics and schema-on-use agility suggest that the Data Lake movement could go much farther than Data Warehousing in enabling diverse, widely-used central repositories of data that can adapt to new data formats and rapidly changing organizations. In that spirit, we advocate rethinking traditional metadata in a far more comprehensive sense. More generally, what we should strive to capture is the full context of data. To emphasize the conceptual shifts of this data context, and as a complement to the “three Vs” of Big Data, we introduce three key sources of information—the ABCs of Data Context. Each represents a major change from the simple metadata of traditional enterprise data management. Applications: Application context is the core information that describes how raw bits get interpreted for use. In modern agile scenarios, application context is often relativistic (many schemas for the same data) and complex (with custom code for data interpretation). Application context ranges from basic data descriptions (encodings, schemas, ontologies, tags), to statistical models and parameters, to user annotations. All of the artifacts involved—wrangling scripts, view definitions, model parameters, training sets, etc.—are critical aspects of application context. Behavior: This is information about how data was created and used over time. In decoupled systems, behavioral context spans multiple services, applications and formats and often originates from highvolume sources (e.g., machine-generated usage logs). Not only must we track upstream lineage— the data sets and code that led to the creation of a data object—we must also track the downstream lineage, including data products derived from this data object. Aside from data lineage, behavioral context includes logs of usage: the “digital exhaust” left behind by computations on the data. As a result, behavioral context metadata can often be larger than the data itself. Change: This is information about the version history of data, code and associated information, including changes over time to both structure and content. Traditional metadata focused on the present, but historical context is increasingly useful in agile organizations. This context can be a linear sequence of versions, or it can encompass branching and concurrent evolution, along with interactions between co-evolving versions. By tracking the version history of all objects spanning code, data, and entire analytics pipelines, we can simplify debugging and enable auditing and counterfactual analysis. Data context services represent an opportunity for database technology innovation, and an urgent requirement for the field. We are building an open-source data context service we call Ground, to serve as a central model, API and repository for capturing the broad context in which data gets used. Our goal is to address practical problems for the Big Data community in the short term and to open up opportunities for long-term research and innovation. In the remainder of the paper we illustrate the opportunities in this space, design requirements for solutions, and our initial efforts to tackle these challenges in open source. 2. DIVERSE USE CASES To illustrate the potential of the Ground data context service, we describe two concrete scenarios in which Ground can aid in data discovery, facilitate better collaboration, protect confidentiality, help diagnose problems, and ultimately enable new value to be captured from existing data. After presenting these scenarios, we explore the design requirements for a data context service. 2.1 Scenario: Context-Enabled Analytics This scenario represents the kind of usage we see in relatively technical organizations making aggressive use of data for machinelearning driven applications like customer targeting. In these organizations, data analysts make extensive use of flexible tools for data preparation and visualization and often have some SQL skills, while data scientists actively prototype and develop custom software for machine learning applications. Janet is an analyst in the Customer Satisfaction department at a large bank. She suspects that the social network behavior of customers can predict if they are likely to close their accounts (customer churn). Janet has access to a rich context-service-enabled data lake and a wide range of tools that she can use to assess her hypothesis. Janet begins by downloading a free sample of a social media feed. She uses an advanced data catalog application (we’ll call it “Catly”) which connects to Ground, recognizes the co

Reported Energy Intake Accuracy Compared to Doubly Labeled Water and Usability of the Mobile Food Record among Community Dwelling Adults

Abstract: The mobile Food Record (mFR) is an image-based dietary assessment method for mobile devices. The study primary aim was to test the accuracy of the mFR by comparing reported energy intake (rEI) to total energy expenditure (TEE) using the doubly labeled water (DLW) method. Usability of the mFR was assessed by questionnaires before and after the study. Participants were 45 community dwelling men and women, 21–65 years. They were provided pack-out meals and snacks and encouraged to supplement with usual foods and beverages not provided. After being dosed with DLW, participants were instructed to record all eating occasions over a 7.5 days period using the mFR. Three trained analysts estimated rEI from the images sent to a secure server. rEI and TEE correlated significantly (Spearman correlation coefficient of 0.58, p < 0.0001). The mean percentage of underreporting below the lower 95% confidence interval of the ratio of rEI to TEE was 12% for men (standard deviation (SD) ± 11%) and 10% for women (SD ± 10%). The results demonstrate the accuracy of the mFR is comparable to traditional dietary records and other image-based methods. No systematic biases could be found. The mFR was received well by the participants and usability was rated as easy.

Traveling-Wave Detection Technique Using Short-Time Matrix Pencil Method

Abstract: This paper proposes a new technique for detection of traveling-wave arrival times in power systems. Precise estimation of wave arrival times improves most of the traveling-wave-based fault location methods. The proposed technique is based on the short-time matrix pencil method that decomposes the measurement samples in a sliding window into time-indexed complex frequencies. Traveling-wave arrival times are estimated based on the fact that the extracted damping factors (i.e., the real part of the complex frequencies) are zero when the arriving wave is located in the middle of the sliding window. The proposed technique is compared to the existing transient-detection techniques such as discrete wavelet transform with commonly used mother wavelets and Hilbert transform (HT), using MATLAB Wavelet Toolbox and MATLAB HT. The sensitivity analysis based on the simulation results demonstrates that the proposed technique is less affected by the measurement noise, sampling frequency, and fault parameters.

Abstract: Context. Considering the importance of software testing to the development of high quality and reliable software systems, this paper aims to investigate how can work-related factors influence the motivation of software testers. Method. We applied a questionnaire that was developed using a previous theory of motivation and satisfaction of software engineers to conduct a survey-based study to explore and understand how professional software testers perceive and value work-related factors that could influence their motivation at work. Results. With a sample of 80 software testers we observed that software testers are strongly motivated by variety of work, creative tasks, recognition for their work, and activities that allow them to acquire new knowledge, but in general the social impact of this activity has low influence on their motivation. Conclusion. This study discusses the difference of opinions among software testers, regarding work-related factors that could impact their motivation, which can be relevant for managers and leaders in software engineering practice.

Performance Analysis of Voice over LTE Using Low-Complexity eMTC Devices

Abstract: The Internet of Things (IoT) is expected to reach a massive scale in the next few years and LTE has introduced a feature in Rel-13 called eMTC to support wide-area connectivity for IoT devices. One important trend for IoT is the integration of voice capability into the devices. However, low-cost, low-complexity IoT User Equipment (UE) typically supports only half-duplex communication and low data rates. In this paper, we compare the performance and coverage of low-complexity eMTC UE with legacy non-eMTC UE for delay-sensitive Voice over LTE (VoLTE) service. It is shown that eMTC UE can provide similar coverage to non-eMTC UE using the same delay and block error rate requirements. If the delay budget or quality of service can be relaxed for eMTC, then eMTC can provide slightly better VoLTE coverage. This allows service operators to support voice capability for IoT devices using existing infrastructure footprint.

The Use of a Multi-modal Interface to Integrate In-Vehicle Information Presentation

Abstract: The car of the future will have many new information sources— including telematics systems, navigation systems and Advanced Driver Assistance Systems (ADAS)—that will compete for a driver’s limited cognitive attention. If they are implemented as completely separate systems then cognitive overload and driver distraction are inevitable outcomes. However, if they are implemented as an integrated intelligent system with a multi-modal interface, then the benefits of such functionality will be achieved with much less impact on driving safety. Such a system will support the task of safe driving by filtering and mediating information in response to real-world driving demands. This paper outlines the Human Factors research program being undertaken by Motorola Labs to evaluate key elements of such a multi-modal interface as well as the key human factors issues involved in a multi-modal interface.

Driver advocate tool

Abstract: Using scenario driven research, a Driver Advocate (DA) system has been designed to advise the driver about potentially unsafe siuations based on information from environmental sensors. DA is an intelligent dynamic system that monitors, senses, prioritizes, personalizes, and sends alerts to the driver appropriate to the moment. This has the potential to sharply decrease driver distraction and inattention. To support the realization of DA, a DA Tool (DAT) has been developed to coordinate with a KQ (previously Hyperion) virtual driving simulator and allow the merging of the simulated driving performance, the environmental sensors, and the intelligent use of audio, visual, and tactile feedback to alert the driver to potential danger and unsafe driving behavior. DAT monitors the traffic, lane following, forward and side clearances, vehicle condition, cockpit distractions, Infotainment use, and the driver affective behavior. The DAT is designed to be highly configurable, flexible, and user friendly to facilitate creative freedom in designing usability and human factors experiments and rapid prototyping. For the covering abstract see ITRD E113119.

Face detection with temperature and distance validation

Abstract: An electronic device incorporates features that are dependent on finding a face by image processing of an image taken by an image capturing device. To avoid false positives and false negatives due to poor focus, exposure, or spoofing with a picture, the electronic device validates, by distance and/or temperature, a candidate face within a captured image. Distance information is used to scale the candidate face to an actual size for comparison against biometric data on a range of sizes of a human face. Detected temperature is compared against biometric data on the temperature of a human face sensed in the infrared spectrum. Confidence value for face detection is increased or decreased in relation to the validation by size/temperature. For a validated candidate having a confidence value above a threshold, the electronic device can adjust camera controls of an image capturing device or enable a face recognition security component.

Directional display and audio broadcast

Abstract: Systems, devices, and techniques for directional display and audio broadcast are described. It is determined whether a spoken query includes an individual query, a group query, and a display request. For an individual query, an audio response is broadcast in a directional manner towards the source of the spoken query. For a group query, an audio response is broadcast in more than one direction, such as towards directions of sources in an environment. For a display request, an image (e.g., picture, video, web page, and the like) is projected on a surface that is detected so the image is viewable by one or more users, such as the source of the spoken query.
