AUTHORS’ VERSION, 2021. TO APPEAR IN IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS 1 The Unmet Data Visualization Needs of Decision Makers within Organizations Evanthia Dimara, Harry Zhang, Melanie Tory, and Steven Franconeri Abstract—When an organization chooses one course of action over alternatives, this task typically falls on a decision maker with relevant knowledge, experience, and understanding of context. Decision makers rely on data analysis, which is either delegated to analysts, or done on their own. Often the decision maker combines data, likely uncertain or incomplete, with non-formalized knowledge within a multi-objective problem space, weighing the recommendations of analysts within broader contexts and goals. As most past research in visual analytics has focused on understanding the needs and challenges of data analysts, less is known about the tasks and challenges of organizational decision makers, and how visualization support tools might help. Here we characterize the decision maker as a domain expert, review relevant literature in management theories, and report the results of an empirical survey and interviews with people who make organizational decisions. We identify challenges and opportunities for novel visualization tools, including trade-off overviews, scenario-based analysis, interrogation tools, flexible data input and collaboration support. Our findings stress the need to expand visualization design beyond data analysis into tools for information management. Index Terms—Decision making, visualization, interview, survey, organizations, management, business intelligence.

    22nd International Congress on Modelling and Simulation, Hobart, Tasmania, Australia, 3 to 8 December 2017 mssanz.org.au/modsim2017 Decision Intelligence in Public Health – DIONE Jacob Stolk1 and Simone Nyon1 1 Dione Complex Systems, Gold Coast, Queensland, Australia Email: [email protected] Abstract: Public health surveillance is the ongoing systematic collection, analysis, interpretation, and dissemination of health data for the planning, implementation, and evaluation of public health action. To achieve effective public health interventions, it is pivotal to analyse and interpret the vast amounts of data collected by surveillance systems to enable good understanding of all factors having an impact on health. For example, we can consider child protection, which is an important public health issue. Often relatively extensive data exist on families in official statistics, research reports, social services reports, school and medical records, etc. However, these data are dispersed and hard if not impossible to relate and compare. This leads to numerous interventions that are conducted without adequate knowledge of target families that are to benefit from these interventions. Inadequate knowledge also leads to lack of intervention where it is needed, such as undetected cases of child abuse. In many cases the basic data that are needed for intervention decisions exist, but are not available to decision makers due to inadequate communication and lack of data integration, analysis and interpretation. Chronic condition management is another area where extensive disparate data exist from statistics and various health services and intervention agencies. In this area too there are numerous organizations offering services and a great need to better coordinate these services to achieve better outcomes for patients and also to reduce soaring costs of the healthcare system.

Welcome to decision intelligence! Source: xijian/Getty Decision intelligence is a new academic discipline concerned with all aspects of selecting between options. It brings together the best of applied data science, social science, and managerial science into a unified field that helps people use data to improve their lives, their businesses, and the world around them. It’s a vital science for the AI era, covering https://towardsdatascience.com/introduction-to-decision-intelligence-5d147ddab767 1/12 10/26/2019 Introduction to Decision Intelligence - Towards Data Science the skills needed to lead AI projects responsibly and design objectives, metrics, and safety-nets for automation at scale. Decision intelligence is the discipline of turning information into better actions at any scale. Let’s take a tour of its basic terminology and concepts. The sections are designed to be friendly to skim-reading (and skip-reading too, that’s where you skip the boring bits… and sometimes skip the act of reading entirely). What’s a decision? Data are beautiful, but it’s decisions that are important. It’s through our decisions — our actions — that we affect the world around us. We define the word “decision” to mean any selection between options by any entity, so the conversation is broader than MBA-style dilemmas (like whether to open a branch of your business in London).

    LINK Link is an exercise in abstraction, causality, and modeling. It is about discovering and making visible interdependencies in complex systems. The author distills what she has learned in pithy insights. It takes discipline. You won’t regret reading this book. À Vint Cerf, Internet Pioneer Link is the missing link to our understanding of unintended consequences of many of our decisions and actions. This is a book for the ages, moving both technology (like AI) and human decision making to the next level. Must read. À V R Ferose, SVP and Head of SAP Academy for Engineering There is an explosion today in the impacts, risks, and opportunities of many decisions by private or governmental entities intended to impact future events. Link is about understanding these decisions and causal relationships. Societal transactions are accelerating: many more than ever are intangible, and there are substantial complexities created by newly discovered information as well as the resulting increase of global interdependencies. Surveillance capitalism, especially as enhanced by AI, is also a substantial risk today. Link is part of the solution: a crucial resource to understand causal chains, especially with the goal of avoiding unintended consequences of decisions involving data and technology.

It identified and discussed the main areas for AI in the finance: portfolio management, bankruptcy prediction, credit rating, exchange rate prediction and trading, and provided numerous examples of the companies that have invested in AI and the type of tasks they use it for. This paper focuses on a stock market prediction, and whether Artificial Neural Networks (ANN), being proxies for Artificial Intelligence, could offer an investor more accurate forecasting results. This study used two datasets: monthly returns of S&P500 index returns over the period 1968-2016, and daily S&P 500 returns over the period of 2007-2017. Both datasets were used to test for univariate and multivariate (with 12 explanatory variables) forecasting. This research used recurrent dynamic artificial neural networks and compared their performance with ARIMA and VAR models, using both statistical measures of a forecast accuracy (MSPE and MAPE) and economic (Success Ratio and Direction prediction) measures. The forecasting was performed for both in-sample and out-of-sample. Furthermore, given that ANN may produce different results during each iteration, this study has performed a sensitivity analysis, checking for the robustness of the results given different network configuration, such as training algorithms and number of lags.
