Dr. Olga Scrivner, "Interactive Visual Data Analysis with Shiny Applications: Interactive Text Mining Suite and Language Variation Suite"

1:30-3pm, Social Science Research Commons Grand Hall (Woodburn Hall 200)

The main objective is to introduce researchers to user-friendly analytical tools. ITMS and LVS are two web-based tools for visualization and quantitative analysis.  In contrast to existing software programs (e.g., SAS, SPSS, and Tableau), these two applications are built in R and require no installation or programming skills.

This hands-on workshop will provide an overview of available statistical and text-mining techniques in these tools. You will learn how to import csv, text and pdf files, create plots, and run statistical analysis, including conditional trees and random forest tests. You will also learn about natural language pre-processing techniques, such as stopwords removal and stemming. Finally, you will be able to perform topic modeling and cluster analysis.

Olga Scrivner is a Visiting Lecturer in Spanish and Portuguese Department. Her research interests lie at the intersection of linguistics, text mining and data visualization.

Dr. Patricia Mabry, "Strategies for Strengthening Grant Proposals"

2-4pm, Social Science Research Commons Grand Hall (Woodburn Hall 200)

Dr. Patricia Mabry is the Executive Director for the IU Network Science Institute (IUNI).  Prior to joining IU in October of  2015, she spent 15 years at the National Institutes of Health. There, among other things, she established an interdisciplinary program in systems science, and served as a member of the Big Data to Knowledge Executive Committee. Because she was in the Office of the Director for the majority of her tenure at NIH, and because of the interdisciplinary focus of her program, she worked with investigators across a broad spectrum of disciplines, and has worked with most of the 27 Institutes and Centers that make up the NIH.  Through these experiences, she came to realize that there were a common core of issues that many investigators shared in common. In this presentation Dr. Mabry will share the compilation of the advice she gave in response to these issues. By attending this presentation, you will: 1) learn to decode NIH-speak, 2) learn how the NIH operates 3) learn specific strategies for strengthening your proposal, 4) hear important differences across funding agencies, 5) learn about peer review 6) learn how to fit your work into funding opportunities, and much more. Even a seasoned investigator is likely to learn something new!

Dr. Mabry is the Executive Director of the Indiana University Network Science Institute (IUNI) and is a Senior Research Scientist in the IU-Bloomington School of Public Health. Through interdisciplinary collaboration, educational offerings, methodological innovation, theoretical development, and provision of supercomputing and IT resources, IUNI nurtures 21st century network science among over 150 affiliated IU faculty. Prior to joining IU in October of 2015, Dr. Mabry had a 15-year career at the National Institutes of Health serving in the National Cancer Institute’s Tobacco Control Research Branch, the Office of Behavioral and Social Sciences Research (OBSSR) and the Office of Disease Prevention (ODP). At NIH Dr. Mabry established and led a systems science program in the behavioral and social sciences and served on the Big Data to Knowledge (BD2K) Executive Committee. She also led ODP’s portfolio analysis tool development team. Dr. Mabry launched her post-doctoral career at the Medical University of South Carolina where she divided her time between teaching behavioral aspects of medicine to medical students, delivering psychological services, and conducting research in tobacco control. She also worked in a small business developing personalized, computer-delivered, behavior change programs (e.g., smoking cessation, dietary and physical activity goal-setting and adherence). Her expertise spans obesity, tobacco control, diabetes, mood disorders, systems science, scientific rigor, and big data. Her work has been published in Science, the American Journal of Public Health, the American Journal of Preventive Medicine, Nicotine & Tobacco Research, and PLoS Computational Biology. Dr. Mabry is a Fellow of the Society of Behavioral Medicine and was a 2008 recipient the Applied Systems Thinking Prize. Dr. Mabry holds a Ph.D. in clinical psychology from the University of Virginia.

NaLette Brodnax, "Introduction to Python and Introduction to Using APIs with Python"

1:30-4:30pm, Social Science Research Commons Grand Hall (Woodburn Hall 200)

 

Part I: Introduction to Python (1:30pm)

Python is a widely used, general purpose programming language.  Part I of the workshop will introduce the basic elements of Python that are commonly used for data cleaning, analysis, visualization, and other applications. Participants will also learn how to set up a "development environment" for Python on their personal computer. Computers with Python pre-loaded are available in the SSRC on a first-come, first-served basis. This workshop is intended for social scientists who are new to programming. No experience is required.

Part II: Introduction to Using APIs with Python (3pm)

An application programming interface (API) is a tool that allows computers to communicate and share information. For social scientists, APIs can be useful for accessing data or services from firms, organizations, or government agencies. Part II of the workshop will introduce the use of APIs to obtain data from sources such as Survey Monkey, Twitter, or Data.gov. This workshop is intended for social scientists who are new to working with APIs, but have some familiarity with Python or have attended the Introduction to Python workshop.

NaLette Brodnax is a data scientist and joint PhD candidate at Indiana University Bloomington in the School of Public and Environmental Affairs and the department of Political Science.  Her fields of specialization include public policy, policy analysis, and quantitative research methodology.

Mathworks Day Seminars: Image Processing, Signal Processing, Machine Learning and Deep Learning in MATLAB

Image Processing, Machine Learning, Computer Vision and Deep Learning in MATLAB

9:30-11:30am, Social Science Research Commons Grand Hall (Woodburn Hall 200)

 

This seminar will be particularly valuable for anyone interested in using MATLAB to process, visualize, and quantify imagery. Rather than focus on extracting information from a few homogeneous images, we will introduce a typical real-world challenge, and discuss approaches to managing and exploring collections of widely heterogeneous images.  We will also describe approaches to implementing deep learning networks in MATLAB, and will compare and contrast those approaches with more traditional computer vision and machine learning techniques.
In this presentation, we will:

  • Explore and manage a range of real-world image sets
  • Solve challenging image processing problems with user interfaces
  • Classify images by content using machine learning techniques
  • Detect, recognize, and track objects and faces in images

12-1pm Pizza lunch

Signal Processing and Machine Learning Techniques for Sensor Data Analytics

1:30-3:30pm, Social Science Research Commons Grand Hall (Woodburn Hall 200)

An increasing number of applications require the joint use of signal processing and machine learning on time series and sensor data. MATLAB can accelerate the development of these systems by providing a full range of modelling and design capabilities within a single environment. In this session we will introduce common signal processing methods (including digital filtering and frequency-domain analysis) that help extract descriptive features from raw waveforms. We will then then discuss how to explore and test different classification algorithms (such as decision trees, support vector machines, or neural networks) to model the system performance. Finally, we will show how to scale the modeling to large datasets and ultimately deploy a streaming classification algorithm with automatic C code generation.

Product Highlights Include:

  • Signal Processing Toolbox
  • DSP System Toolbox
  • Statistics and Machine Learning Toolbox
  • Neural Network Toolbox
  • Parallel Computing Toolbox
  • MATLAB Coder
