Ad-hoc Data Exploration using Conversational AI

Anand Ranganathan, Chief AI Officer at Unscrambl

Conversational AI is getting more and more widely used for customer support and employee support use-cases. In this session, I'm going to talk about how it can be extended for data analysis and data science use-cases, i.e., how users can interact with a bot to ask ad-hoc analytical questions on data in relational databases. This allows people to explore complex datasets using a combination of text and voice questions, in natural language, and then get back results in a combination of natural language and visualizations. For example, they can ask questions like "How many cases of Covid were there in the last 2 months by state and gender" or "Why did the number of deaths from Covid increase in May 2022", and get back results in a combination of text and charts.

Human-AI collaborative knowledge discovery in tradespace exploration

Dani Selva, Assistant Professor of Aerospace Engineering at Texas A&M UniversityDani_Selva_2022

Tradespace exploration is a method used in the early design of complex systems to explore a wide range of design alternatives across conflicting figures of merit in a rigorous and systematic way. AI tools have been used in tradespace exploration for decades, primarily to improve efficiency in the evaluation and search of the design space. However, what engineers need from AI is more than just better design optimization/search capabilities to find the best possible designs according to the models. Engineers need to learn what is driving those results, why they are getting those results, and under what circumstances they remain valid, so they can justify their design decisions to stakeholders. In summary, the goal is insight, a rather subjective and ill-defined construct that has been studied in the visual and data analytics community for decades. In this talk, I advocate for the use of AI agents to help engineers explore the large and complex datasets resulting from tradespace exploration in the context of their own knowledge and expertise of the problem. I will summarize a few studies we have done in my lab to better understand what humans learn in design space exploration, how AI assistants can maximize that learning, and the subtle relationship between how much engineers learn about a problem and other more traditional outcomes of tradespace exploration such as the quantity, quality and diversity of designs explored.

Dr. Zoe Szajnfarber

Professor and Chair of the Department of Engineering Management
and Systems Engineering, George Washington University

Abstract: The Designing Trustworthy AI Systems (DTAIS) program is built around a core tension between the opportunity for ubiquitous AI to transform work for social good and the emergent risks around bias, security and privacy that arise as AI tools are increasingly embedded in core routines and value generating institutional functions. This presentation will provide an overview of DTAIS research on trust and system architecture, focusing on two in-progress studies. First, in the context of image classification, we explore how a typical focus on accuracy scores (this classifier is 89% accurate) can hide critical differences in the distribution of classification errors (when it’s wrong, how wrong is it?). We relate differences in error distribution to the formation of trust among end-users. Second, in the context of human in/on-the-loop AI systems, we examine perceived and revealed differences between human control over the systems, and discuss the implications of these differences for policy.

Presenter: Dr. Zoe Szajnfarber is Professor and Chair of the Department of Engineering Management and Systems Engineering at the George Washington University. She is also the PI and co-Director of the NSF-funded Designing Trustworthy AI Systems (DTAIS) traineeship program.

Abstract: The talk will discuss algorithmic bias, fairness metrics and bias mitigation practices and end with a discussion of algorithmic harms to evaluate fairness metrics. The specific example of digital health literacy will be examined. Studies suggest that one in three US adults use the Internet to diagnose or learn about a health concern. However, such access to health information online could exacerbate the disparities in health information availability and use. Health information seeking behavior (HISB) refers to the ways in which individuals seek information about their health, risks, illnesses, and health-protective behaviors. For patients engaging in searches for health information on digital media platforms, health literacy divides can be exacerbated both by their own lack of knowledge and by algorithmic recommendations, with results that disproportionately impact disadvantaged populations, minorities, and low health literacy users. I will report on exploratory investigation of the above challenges by examining whether responsible and representative recommendations can be generated using advanced analytic methods applied to a large corpus of videos and their metadata on a chronic condition (diabetes) from the YouTube social media platform.

Introduction to Trustworthiness in Computing Systems

Foundations for AI 

Picture2

Abstract: General concepts of trust in AI and autonomous systems can be derived from engineering concepts of dependable and secure computing systems. In computing systems, trust is formally defined as the dependence of one system on another, and the acceptance that the other system is also dependable. [Avižienis, et al, 2004]. This 

dependence can be either human/machine or machine/machine. Resilience is related to trustworthiness as the ability of the system to withstand instability, unexpected conditions, and gracefully return to predictable, but possibly degraded, performance. This is a system-of-systems concern, and trust must be considered as both a characteristic of an individual system or subsystem and as relationships between the system and other systems including humans. In systems engineering, trust can be categorized into a s

et of dependability and security attributes: the ability of a system to avoid service failures and cover the interrelated foundational attributes of availability, reliability, safety, integrity, confidentiality, and maintainability. These attributes work together to ensure the system’s successful application, and demonstration of those attributes over time engenders trust. Thus, trust is a systems engineering concept. In this talk we will explore modeling trust as a set of system attributes.

AI Explainability and AI in Sci-FI

May 4, 2022 A tour of the subject of explainable AI—a very hot topic in AI these days. After that, in honor of Star Wars Day, we’ll take a look at how AI appears in Star Wars, and Star Trek also, and see how AI is depicted in the science fiction future.

A System Engineer’s Guide to Explainable AI

Abstract: System Engineers (SEs) are faced with incorporating Artificial Intelligence and Machine Learning (AI/ML) based solutions into modern systems for meeting complex technological and societal needs. It is imperative for SEs to characterize the behavior of AI/ML based components that often appears as black boxes even to the component designers. This talk will introduce key concepts of Explainable AI (XAI) that creates a window into the black-box nature of AL/ML based component. We will debunk some common myths about explainability and discuss how SEs can utilize XAI for test and evaluation of systems with AI/ML-components.

Barclay_BrownEverything I Know about Artificial Intelligence I Learned from the Movies

Abstract: Much of what most people “know” about artificial intelligence traces its source to science fiction mythology. Science fiction representations of robots, created minds, and intelligent machines spans a wide range of perspectives. Speculative books may describe possible futures of AI, but movies and TV series can show what a world would be like if these scenarios became reality. Star Wars and Star Trek, show nearly polar opposites in how AI turns out in a highly advanced human (and non-human) civilization.
