AutoML for Classification of Human Movement and Biomechanics

Date/Time: Monday, April 25, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Dr. Corey Pew

Abstract: Classification and prediction of human movement is an important research topic in biomechanics and health. Classifying the motion of users in real-time is necessary for controlling robotic prosthetics, orthotics, and exoskeletons. In addition, the ability to identify abnormal gait or an adverse event, such as a fall, would provide prompt, objective data that allows researchers and clinicians to better understand a patient’s needs objectively and accurately. To achieve this goal, researchers utilize body worn sensors (inertial measurement units (IMUs), surface electromyography, load cells, etc.) combined with machine learning classifiers to identify various walking modes and user intent. Classifiers take input from sensors by collecting raw data on body movement, which is then translated into classifications of activity such as walking, sitting, standing, stair climbing, and more. Because researchers in the biomechanics field are often not deeply familiar with best practices in machine learning there is a tendency to inappropriately use premade classifiers and boast success through reports of high classification accuracy. It is the goal of our project to create an AutoML pipeline that addresses the specific challenges of biomechanics data that helps to mitigate classifier misuse while also educating the user of the best practices when implementing machine learning classifiers with their data. In addition, we seek to utilize AutoML to facilitate the implementation of personalized classifiers at the clinical level to help bridge the gap between theory and application in the field.

Bio: Dr. Pew is an Assistant Professor in the Mechanical and Industrial Engineering Department at Montana State University. His research interests are focused on biomechanics and human-machine interactions with applications to the advancement of lower limb amputee technologies. This includes the design of new amputee devices as well as sensing and control schemes to facilitate two-way communication between the user and the prosthetic device. Control employs the use of body-worn sensors such as inertial measurement units and electromyography as well as the development of machine learning techniques to translate that motion information into identifiable control signals. In addition, I have interests related to running and human performance evaluation and improvement. 

Assessing Forecast Performance of Empirical Crop Response Models using Precision Agriculture and On-Farm Precision Experimentation

Date/Time: Monday, April 18, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Paul Hegedus

Abstract: Precision agroecology leverages the data derived from precision agriculture technology to characterize ecological relationships between crop responses, the environment, and agronomic inputs. Decision support systems utilize models that describe these relationships to generate management recommendations for agronomic inputs, such as nitrogen fertilizer. Yet there is uncertainty in the literature on the best model forms to characterize crop responses to agricultural inputs, likely due to the variability in crop responses to inputs between fields and across years. Seven fields with at least three years of experimentally varied nitrogen fertilizer rates were used to compare the ability of five different model types to forecast crop responses and net-returns. The five model types for each field were investigated using all permutations of the three years of data, where two years were used for training and a third was held out to represent a “future” year. The five models tested were a frequentist based non-linear sigmoid function, a generalized additive model, a non-linear Bayesian regression model, a Bayesian multiple linear regression model, and a random forest regression model. The random forest regression typically resulted in the most accurate forecasts of crop responses and net-returns across most fields. However, in some cases the model type that produced the most accurate forecast of grain yield was not the same as the model producing the most accurate forecast of grain protein concentration. Models performed best when the data used for training models was collected from years with similar weather conditions to the forecasted year. The results are important to developers of decision support tools to minimize assumptions when selecting models used for simulating management outcomes and deriving economically and ecologically optimized nitrogen fertilizer rates.

Understanding and Addressing Public Distrust of AI & Autonomous Systems

Date/Time: Monday, April 11, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Dr. Kristen Intemann

Abstract: According to a 2017 Pew Research poll, twice as many U.S. adults say they are “more concerned than excited” about the increased use of intelligent and autonomous systems and nearly half say that they are “as concerned as they are excited about AI.” This is worrisome given the numerous ways that such systems are being increasingly turned to in developing tools to be used in virtually every aspect of human life including: healthcare, agriculture, marketing, social media, transportation, and policing. This talk will present a variety of reasons that segments of the public have for distrusting of both particular applications as well as artificial and intelligent systems more generally. Understanding the sources of distrust is vital for identifying strategies that would increase trust and produce responsible and fair intelligent and autonomous systems.

What if Algorithms Weren’t the Ghost in the Machine? Using Explainable AI (XAI) Methods to Turn Algorithmic User Experiences into Research Data Objects

Date/Time: Monday, March 28, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Jason Clark

Abstract:Jason A. Clark, Professor and Lead for Research Optimization, Analytics, and Data Services (ROADS) at MSU Library, will be discussing his research developing software and a curriculum to support the teaching of "Algorithmic Awareness": an understanding around the rules that govern our software and shape our digital experiences. Taking inspiration from investigative data journalists, like The Markup, Jason will introduce a research module for algorithm auditing practices using code, web scraping methods, and structured data formats to uncover proprietary algorithms and turn them into research data objects for analysis. (Code is available in our #AlgorithmicAwareness GitHub repository.) The case study for the module will be the YouTube Video Recommendation Algorithm which has come under criticism for its tactics in drawing parents’ and childrens’ attention to their videos. The goal will be to show the generic patterns, data points, and scripts one can use to analyze algorithmic user experiences and demonstrate how code can be used to turn algorithms into datasets for analysis. In the end, attendees will be able to realize actionable steps for seeing algorithms as data objects, gain a sense of the first steps one can take to programmatically audit these systems with code, and take away investigative data techniques for applying Explainable AI methods to your own work and teaching.

Statistical Inference in Topological Data Analysis

Date/Time: Monday, March 21, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Jordan Schupbach

Abstract: Topological data analysis (TDA) is a fairly newinterdisciplinary field that seeks to represent the shape of data using tools from algebraic topology. It has the ability to distill complex structural information present in high-dimensional datasets. However, methods for analyzing these representations under non-trivial sampling designs are few to non-existent and as a result are rarely employed in practice. Persisence intensity functions are a common topological descriptor in used in the field of TDA.  In this talk, novel methods for conducting hypothesis testing with persistence intensity functions in the setting of hierarchical sampling designs will be presented.

Bio: Jordan Schupbach is a PhD student in statistics at Montana State University co-advised by John Borkowski and John Sheppard. His primary research involves conducting statistical and predictive inference for topological data analysis (TDA) using a point process methodology. At MSU, he has been involved in conducting research using a TDA methodology for predicting progression of prostate cancer and in using Bayesian networks for conducting diagnostics and prognostics in systems health management. His general research interests include machine learning, Bayesian statistics, nonparametric statistics, spatial statistics, and functional data analysis.

Solving Industrial Optimization Problems with Quantum Annealing

Date/Time: Monday, March 7, 4:10 p.m - 5:00 p.m. via MS TEAMS
Speaker: Dr. Alexander Feldman, PARC

Abstract: Quantum annealing machines become an important tool in solving problems of industrial significance. Experimentation in areas such as circuit diagnostics and Automated Test Pattern Generation (ATPG) indicate that quantum annealers will soon outperform classical methods. Despite this, due to hardware limitations, there will always be problems that are too big for the underlying hardware. One way of approaching these large problems is to preprocess and split them.

In this talk we will discuss hybrid methods for solving circuit diagnosis, ATPG, satisfiability and other problems from combinatorial optimization. The emphasis is on preprocessing and on the tool-chain that converts the input problem to a representation suitable for quantum annealing. We will show several advanced techniques for reducing the number of ancillary variables. These techniques significantly improve the performance of the hybrid optimization process.

We will also discuss a class of more difficult problems related to circuit synthesis. These are in the second level of the polynomial hierarchy. Solving them will answer important questions related to quantum computing and the scalability of this promising technology.

Exploration of Multi-Objective Optimization in the Factored Evolutionary Framework

Date/Time: Monday, February 28, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Amy Peerlinck

Abstract: Multi-Objective Optimization (MOO) looks at problems with two or more competing objectives. Such problems occur naturally in the real world. For example, many engineering design problems have to deal with competing objectives, such as cost versus quality in product design. How do we handle these competing objectives? To answer this question, meta-heuristic algorithms that find a set of Pareto optimal solutions have become a popular approach. However, with the increase in complexity of problems, a single population approach may not be the most efficient to solve large scale multi-objective optimization problems. For this reason, co-operative co-evolutionary algorithms (CCEA) are used, which split the population into subpopulations optimizing over subsets of variables that can now be optimized simultaneously. Factored Evolutionary Algorithms (FEA) extends the CCEA idea by including overlap in the subpopulations. So far, FEA has not been applied to the field of MOO, but we believe it could be an effective alternative approach to help solve these types of problems. In this talk, we lay out our plan to research the impact of different ways to create subpopulations and how it influences large-scale and multi-objective optimization. We intend to look at the influence of overlapping and distinct variable decompositions, as well as objective decomposition approaches for MOO.

Authoring Social Interactions Between Humans and Robots

Date/Time: Monday, February 7, 4:10 p.m. - 5:00 p.m. in Barnard 108
Speaker: David Porfirio

Abstract: Robots serve as interaction partners to humans in the workplace, at home, and for leisure activities, but designing social human-robot interactions (HRIs) is non-trivial. Challenges arise from the need to create interaction experiences that are successful with respect to both task and social outcomes. In particular, HRI developers must manage the low-level details of a robot program, such as asynchronously sensing external input while producing concurrent behaviors like speech and locomotion, while manipulating the robot’s higher-level decision making to produce a natural interaction flow. A further challenge includes the differing success criteria for HRIs within separate interaction contexts, in that developers must consider the end-user constraints and preferences specific to each individual context within which the robot will be deployed. In this talk, I will present my past research and plans for future work on how HRI development approaches can help mitigate these challenges. Approaches of interest include software or hardware interfaces and assistive algorithms made specifically for programming robots. I seek to answer how these development tools and techniques can support HRI developers in creating robust interaction designs by (1) filling in gaps in developer knowledge and expertise and (2) eliciting knowledge already possessed by developers and assisting with the integration of this knowledge into robot programs. 

Bio: David Porfirio is a Ph.D. candidate at the University of Wisconsin–Madison. His interests lie in investigating and designing human-robot interaction development tools that make the process of programming social robots easy and approachable for experts and non-experts alike. David has received numerous fellowships and awards during his Ph.D., including the NSF Graduate Research Fellowship, the Microsoft Dissertation Grant, and a best paper award for his work on formally verifying social norms in human-robot interaction designs. Prior to his research at UW–Madison, David earned bachelor’s degrees in computer science and human physiology from the University of Arizona.

Automated AI: Aspirations and Perspirations

Date/Time: Monday, January 31, 4:10 p.m - 5:00 p.m. in Barnard Hall 108
Speaker: Dr. Lars Kotthof

Abstract: AI and machine learning are ubiquitous, but AI and ML experts are not. Arguably, at least some of the tasks those scarce experts are tackling do not make the best use of their skills and expertise — manually tweaking heuristics and hyperparameter settings is tedious but relatively straightforward. Automating these tasks allows the human experts to focus on the interesting and creative work.  In this talk, I will outline the aspirational goal of automating large parts of AI that are currently painstakingly done by human experts, including engineering AI software. I will describe some of the progress that has been made to date, in particular in automated machine learning. The talk will conclude with a broader outlook on how the development of automated AI has positive impacts in other fields, using Materials Science as an example.

Bio: Lars Kotthoff is an assistant professor at the University of Wyoming and held post-doctoral appointments at the University of British Columbia, Canada, University College Cork, Ireland, and the University of St Andrews, Scotland.
