Spatial Data Mining I: Essentials of Cluster Analysis
Whenever we look at a map, it is natural for us to organize, group, differentiate, and cluster what we see to help us make better sense of it. This session will explore the powerful Spatial Statistics techniques designed to do just that: Hot Spot Analysis and Cluster and Outlier Analysis. We will demonstrate how these techniques work and how they can be used to identify significant patterns in our data. We will explore the different questions that each tool can answer, best practices for running the tools, and strategies for interpreting and sharing results. This comprehensive introduction to cluster analysis will prepare you with the knowledge necessary to turn your spatial data into useful information for better decision making.

STEPS: Spatio-temporal Electric Power Systems Visualization
As the bulk electric grid becomes more complex, power system operators and engineers have more information to process and interpret than ever before. The information overload they experience can be mitigated by effective visualizations that facilitate rapid and intuitive assessment of the system state. With the introduction of nondispatchable renewable energy, flexible loads, and energy storage, the ability to temporally explore system states becomes critical. This paper introduces STEPS, a new 3D Spatio-temporal Electric Power Systems visualization tool suitable for steady-state operational applications.

IntelliLight: a Reinforcement Learning Approach for Intelligent Traffic Light Control
Authors: Hua Wei (The Pennsylvania State University); Guanjie Zheng (The Pennsylvania State University); Huaxiu Yao (The Pennsylvania State University); Zhenhui Li (The Pennsylvania State University) Abstract: The intelligent traffic light control is critical for an efficient trans- portation system. While existing traffic lights are mostly operated by hand-crafted rules, an intelligent traffic light control system should be dynamically adjusted to real-time traffic. There is an emerging trend of using deep reinforcement learning technique for traffic light control and recent studies have shown promising results. However, existing studies have not yet tested the methods on the real-world traffic data and they only focus on studying the rewards without interpreting the policies. In this paper, we propose a more effective deep reinforcement learning model for traffic light control. We test our method on a large-scale real traffic dataset obtained from surveillance cameras. We also show some interesting case studies of policies learned from the real data. More on http://www.kdd.org/kdd2018/

3D Spatial Data Mining on Document Sets
The retrospective fault analysis of complex technical devices based on documents emerging in the advanced steps of the product life cycle can reveal error sources and problems, which have not been discovered by simulations or other test methods in the early stages of the product life cycle. This video presents a novel approach to support the failure analysis through (i) a semi-automatic analysis of databases containing product-related documents in natural language (e.g. problem and error descriptions, repair and maintenance protocols, service bills) using information retrieval and text mining techniques and (ii) an interactive exploration of the data mining results. Our system supports visual data mining by mapping the results of analyzing failure-related documents onto corresponding 3D models. Thus, visualization of statistics about failure sources can reveal problem sources resulting from problematic spatial configurations. This video can be found in high quality at wwwisg.cs.uni-magdeburg.de/~timo/videos/3DSpDataMining.avi The associated scientific publication available at wwwisg.cs.uni-magdeburg.de/~timo/ was published at the 2nd International Conference on Computer Graphics Theory and Applications (GRAPP'07)

Chronodes: Interactive Multi-focus Exploration of Event Sequences.
The advent of mobile health (mHealth) technologies challenges the capabilities of current visualizations, interactive tools, and algorithms. We present Chronodes, an interactive system that unifies data mining and human-centric visualization techniques to support explorative analysis of longitudinal mHealth data. Chronodes extracts and visualizes frequent event sequences that reveal chronological patterns across multiple participant timelines of mHealth data. It then combines novel interaction and visualization techniques to enable multi-focus event sequence analysis, which allows health researchers to interactively define, explore, and compare groups of participant behaviors using event sequence combinations. rough summarizing insights gained from a pilot study with 20 behavioral and biomedical health experts, we discuss Chronodes’s efficacy and potential impact in the mHealth domain. Ultimately we outline important open challenges in mHealth, and offer recommendations and design guidelines for future research. For a video demonstration of Chronodes, please refer to the provided video figure. Chronodes: Interactive Multi-focus Exploration of Event Sequences. Peter J.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Geospatial analysis, or just spatial analysis, is an approach to applying statistical analysis and other analytic techniques to data which has a geographical or spatial aspect. Such analysis would typically employ software capable of rendering maps processing spatial data, and applying analytical methods to terrestrial or geographic datasets, including the use of geographic information systems and geomatics. Geographic information systems (GIS), which is a large domain that provides a variety of capabilities designed to capture, store, manipulate, analyze, manage, and present all types of geographical data, and utilizes geospatial analysis in a variety of contexts, operations and applications. Geospatial analysis, using GIS, was developed for problems in the environmental and life sciences, in particular ecology, geology and epidemiology. It has extended to almost all industries including defense, intelligence, utilities, Natural Resources (i.e. Oil and Gas, Forestry ... etc.), social sciences, medicine and Public Safety (i.e. emergency management and criminology), disaster risk reduction and management (DRRM), and climate change adaptation (CCA). Spatial statistics typically result primarily from observation rather than experimentation. Vector-based GIS is typically related to operations such as map overlay (combining two or more maps or map layers according to predefined rules), simple buffering (identifying regions of a map within a specified distance of one or more features, such as towns, roads or rivers) and similar basic operations. This reflects (and is reflected in) the use of the term spatial analysis within the Open Geospatial Consortium (OGC) “simple feature specifications”. For raster-based GIS, widely used in the environmental sciences and remote sensing, this typically means a range of actions applied to the grid cells of one or more maps (or images) often involving filtering and/or algebraic operations (map algebra). These techniques involve processing one or more raster layers according to simple rules resulting in a new map layer, for example replacing each cell value with some combination of its neighbours’ values, or computing the sum or difference of specific attribute values for each grid cell in two matching raster datasets. Descriptive statistics, such as cell counts, means, variances, maxima, minima, cumulative values, frequencies and a number of other measures and distance computations are also often included in this generic term spatial analysis. Spatial analysis includes a large variety of statistical techniques (descriptive, exploratory, and explanatory statistics) that apply to data that vary spatially and which can vary over time. Some more advanced statistical techniques include Getis-ord Gi* or Anselin Local Moran's I which are used to determine clustering patterns of spatially referenced data. Geospatial analysis goes beyond 2D and 3D mapping operations and spatial statistics. It includes: Surface analysis —in particular analysing the properties of physical surfaces, such as gradient, aspect and visibility, and analysing surface-like data “fields”; Network analysis — examining the properties of natural and man-made networks in order to understand the behaviour of flows within and around such networks; and locational analysis. GIS-based network analysis may be used to address a wide range of practical problems such as route selection and facility location (core topics in the field of operations research, and problems involving flows such as those found in hydrology and transportation research. In many instances location problems relate to networks and as such are addressed with tools designed for this purpose, but in others existing networks may have little or no relevance or may be impractical to incorporate within the modeling process....

Leadline: Interactive Visual Analysis of Text Data through Event Identification and Exploration
Contact: Dr. Wenwen Dou (wdou1 at uncc dot edu) at the Charlotte Visualization Center (http://www.viscenter.uncc.edu) Description of the Project: Text data such as online news and microblogs bear valuable insights regarding important events and responses to such events. Events are inherently temporal, evolving over time. Existing visual text analysis systems have provided temporal views of changes based on topical themes extracted from text data. But few have associated topical themes with events that cause the changes. In this paper, we propose an interactive visual analytics system, LeadLine, to automatically identify meaningful events in news and social media data and support exploration of the events. To characterize events, LeadLine integrates topic modeling, event detection, and named entity recognition techniques to automatically extract information regarding the investigative 4 Ws: who, what, when, and where for each event. To further support analysis of the text corpora through events, LeadLine allows users to interactively examine meaningful events using the 4 Ws to develop an understanding of how and why. Through representing large-scale text corpora in the form of meaningful events, LeadLine provides a concise summary of the corpora. LeadLine also supports the construction of simple narratives through the exploration of events. To demonstrate the efficacy of LeadLine in identifying events and supporting exploration, two case studies were conducted using news and social media data.

Considering Agency and Data Granularity in the Design of Visualization Tools
Considering Agency and Data Granularity in the Design of Visualization Tools Gonzalo Gabriel Méndez, Miguel A. Nacenta, Uta Hinrichs CHI '18: ACM CHI Conference on Human Factors in Computing Systems Session: Designing and Creating Visualizations Abstract Previous research has identified trade-offs when it comes to designing visualization tools. While constructive ``bottom-up'' tools promote a hands-on, user-driven design process that enables a deep understanding and control of the visual mapping, automated tools are more efficient and allow people to rapidly explore complex alternative designs, often at the cost of transparency. We investigate how to design visualization tools that support a user-driven, transparent design process while enabling efficiency and automation, through a series of design workshops that looked at how both visualization experts and novices approach this problem. Participants produced a variety of solutions that range from example-based approaches expanding constructive visualization to solutions in which the visualization tool infers solutions on behalf of the designer, e.g., based on data attributes. On a higher level, these findings highlight agency and granularity as dimensions that can guide the design of visualization tools in this space.

Real-Time Animated Visualization of Massive Air-Traffic Trajectories
With increasing numbers of flights world-wide and a continuing rise in airport traffic, air-traffic management is faced with a number of challenges. These include monitoring, reporting, planning, and problem analysis of past and current air traffic, e.g., to identify hotspots, minimize delays, or to optimize sector assignments to air-traffic controllers. Interactive and dynamic 3D visualization and visual analysis of massive aircraft trajectories, i.e., analytical reasoning enabled by interactive cyber worlds, can be used to approach these challenges. To facilitate this kind of analysis, especially in the context of real-time data, interactive tools for filtering, mapping, and rendering are required. In particular, the mapping process should be configurable at run-time and support both static mappings and animations to allow users to effectively explore and realize movement dynamics. However, with growing data size and complexity, these stages of the visualization pipeline require computational efficient implementations to be capable of processing within real-time constraints. This paper presents an approach for real-time animated visualization of massive air-traffic data, that implements all stages of the visualization pipeline based on GPU techniques for efficient processing. It enables (1) interactive spatio-temporal filtering, (2) generic mapping of trajectory attributes to geometric representations and appearances, as well as (3) real-time rendering within 3D virtual environments, such as virtual 3D airport and city models. Based on this pipeline, different visualization metaphors (e.g., temporal focus+context, density maps, and overview+detail visualization) are implemented and discussed. The presented concepts and implementation can be generally used as visual analytics and data mining techniques in cyber worlds, e.g., to visualize movement data, geo-referenced networks, or other spatio-temporal data.

Dive In! Enabling Progressive Loading for Real-Time Navigation of Data Visualizations
http://www.autodeskresearch.com/publications/divein We introduce Splash, a framework reducing development overhead for both data curators and visualization develop-ers of client-server visualization systems. Splash stream-lines the process of creating a multiple level-of-detail ver-sion of the data and facilitates progressive data download, thereby enabling real-time, on-demand navigation with ex-isting visualization toolkits. As a result, system responsive-ness is increased and the user experience is improved. We demonstrate the benefit of progressive loading for user in-teraction on slower networks. Additionally, case study evaluations of Splash with real-world data curators suggest that Splash supports iterative refinement of visualizations and promotes the use of exploratory data analysis. ___________________ Michael Glueck, Azam Khan & Daniel Wigdor.

Science for the Green Economy Seminar Series - Big Data & Environmental Informatics
www.cranfield.ac.uk/sas/s4ge This seminar, held on 14 May 2014, discussed how current research activities in environmental informatics are addressing this need, touching on approaches such as data mining, statistical interpretation, and predictive analytics for handling such 'big data'. Chaired by Professor Simon Pollard, Cranfield University and Julie Vaughan, Senior Associate, Herbert Smith Freehills LLP. Today the sheer volume of environmental 'big data' gathered by real-time sensors, data loggers, satellite and aerial remote observation platforms, machinery and simulation outputs, such as climate-change models, can challenge traditional methods for structuring, manipulating and outputting digital information used for decision support. Such spatio-temporal knowledge is required to improve our understanding and management of environmental systems. New informatics techniques can help address this challenge.

Four Pillars of Data Visualization (Open Talk) @ DataWeek 2013
http://BizCloudNetwork.com http://BizCloud.net This talk discusses the broad design considerations necessary for effective visualizations. Attendees will learn what's required for a visualization to be successful, gain insight for critically evaluating visualizations they encounter, and come away with new ways to think about the visualization design process. To be most effective, a visualization must have, in this order: - Purpose (Why are we creating this visualization? Who is it for?) - Content (What data matters? What relationships matter?) - Structure (How do we best reveal those data and relationships?) - Formatting (How does it look & feel? How will it be consumed?) This talk will define these four pillars, reveal why they must be selected in this order, and discuss the importance and impact each has on your visualization. Noah Iliinsky Visualization Expert, IBM Noah Iliinsky strongly believes in the power of intentionally crafted communication. He has spent nearly 10 years thinking, writing, and speaking about best practices for designing visualizations, informed by his graduate work in user experience and interaction design.

AllAboard: Visual Exploration of Cellphone Mobility Data to Optimise Public Transport
The deep penetration of mobile phones offers cities the ability to opportunistically monitor citizens’ mobility and use datadriven insights to better plan and manage services. With large scale data on mobility patterns, operators can move away from the costly, mostly survey based, transportation planning processes, to a more data-centric view, that places the instrumented user at the center of development. In this framework, using mobile phone data to perform transit analysis and optimization represents a new frontier with significant societal impact, especially in developing countries. In this paper we present AllAboard, an intelligent tool that analyses cellphone data to help city authorities in visually exploring urban mobility and optimizing public transport. This is performed within a self contained tool, as opposed to the current solutions which rely on a combination of several distinct tools for analysis, reporting, optimisation and planning. An interactive user interface allows transit operators to visually explore the travel demand in both space and time, correlate it with the transit network, and evaluate the quality of service that a transit network provides to the citizens at very fine grain. Operators can visually test scenarios for transit network improvements, and compare the expected impact on the travellers’ experience. The system has been tested using real telecommunication data for the city of Abidjan, Ivory Coast, and evaluated from a data mining, optimisation and user prospective.

Interactive Visualizations of Temporal Event Sequences
Catherine Plaisant, University of Maryland Presents... Interactive Visualizations of Temporal Event Sequences (with a focus on Electronic Health Record data). Sequences of events are part of people's life, their travel, hospital visits, even web browsing experiences. Specifying temporal queries to explore collections of event sequences can be challenging even for skilled computer professionals. We will review a series of visualization techniques developed at the Human-Computer Interaction lab over the years to handle temporal data, with a particular focus on the benefits - and challenges - of interaction during the analysis process. Our novel strategies allow for aligning records on important events, ranking, and filtering combined with grouping of results to find common or rare events. Other approaches explore query-by-example, or methods to aggregate thousands of event sequences. Video demonstrations will focus on electronic health record data. Finally we will discuss the methods we use to evaluate the usefulness of our interactive visualizations through case studies developed in collaboration with clinical researchers. Catherine Plaisant is Senior Research Scientist at the Human-Computer Interaction Lab of the University of Maryland Institute for Advanced Computer Studies. She earned her PhD in France before joining the HCIL to work on diverse subjects such as information visualization, evaluation methods, technology for families, digital libraries, online help, etc. She co-authored with Ben Shneiderman the 4th and 5th Editions of Designing the User Interface, one of the major books on the topic of Human-Computer Interaction. She enjoys working with multidisciplinary teams on designing and evaluating new interface technologies that are useable and useful. Research contributions range from focused user interaction techniques (e.g. Excentric Labeling) to innovative visualizations (such as LifeLines for personal records or SpaceTree for hierarchical data exploration) and interactive search interface techniques such as Query Previews. Those interaction techniques have been carefully validated with user studies and have found applications in industry, government information systems and digital libraries.

EventRiver - Prototype Visual Analytics System for Exploring Large-Scale News Text Collections
—Many Text Collections with a Temporal Focus (TCTFs), such as news corpora and weblogs, are generated to report and discuss real life events. Thus Event-Related Tasks (ERTs), such as detecting the real life events driving the text, tracking their evolution, and investigating the reports and discussions around these events, are important when exploring such text collections. In this paper, we propose a novel visual analytics approach named EventRiver to help users conduct ERTs that incorporates and leverages human efforts. EventRiver employs a novel incremental streaming text clustering algorithm to detect clusters with temporal locality from TCTFs, which can be mapped to real life events driving the text generation. The clustering is based on a streaming data model so that newly arrived documents can be processed without re-processing the existing documents. The semantics of the clusters, their strengths over time, and the relationships among the clusters are automatically captured and visually presented to users. The users can then conduct the ERTs using the rich set of interactions provided in EventRiver. A working prototype of EventRiver has been implemented for exploring news corpora. A set of user studies, experiments, and a formal user study have been conducted to evaluate its effectiveness and efficiency.

MultiLens: Fluent Interaction with Multi-Functional Multi-Touch Lenses for Information Visualization
We propose MultiLens, touch-enabled magic lenses for fluently manipulating functions, parameters, and combinations of lenses on interactive surfaces. We contribute a novel multi-touch menu technique for magic lenses using a widget-based approach with a drag-snap slider for relative parameter adjustment. We also propose a continuous gesture set for rapidly changing lenses and their primary parameters in one seamless phrase. In addition, by supporting the combination of various lens functions, we create a generic multi-purpose lens tool. We illustrate our approach by investigating and implementing the concepts for the field of graph exploration. The prototype was evaluated in a user study with 22 participants comparing it to traditional parameter menus operated with both mouse and touch. This work was published at ISS'16, see http://dx.doi.org/10.1145/2992154.2992168 or http://imld.de for more information.

Andean porphyry-copper ore deposits and plate tectonic evolution
This animation illustrates absolute plate motions and plate boundary evolution of Gondwanaland during its breakup and tectonic plates in the Pacific ocean basin. The paleo-age-area distribution of the ocean floor is shown with red/orange colours indicating young ocean floor (0-50 million years) and cool colours (yellow/green) relatively old ocean floor (between 50 and 100 million years old) (plate model from Müller et al, 2016). The red-white-blue band along subduction zones indicates the plate convergence speed. The small dots along the western South American margin which appear through time correspond to porphyry copper-gold deposits. In a paper published in Tectonics, Butterworth et al. (2016) combined plate tectonic parameters like convergence speed, obliquity and age of the subducting crust with machine learning methods to determine key tectonic parameters which favour the formation of porphyry copper-gold deposits.
