Session Logistics

Overview

This course will be based on a Data Science and Predictive Analytics (DSPA) course the instructor teaches at the University of Michigan. The training will provide intermediate to advanced learners with a solid data science foundation to address challenges related to collecting, managing, processing, interrogating, analyzing and interpreting complex health and biomedical datasets using R. Participants will gain skills and acquire a tool-chest of methods, software tools, and protocols that can be applied to a broad spectrum of Big Data problems.

Before diving into the mathematical algorithms, statistical computing methods, software tools, and health analytics, we will discuss a number of driving motivational problems. These will ground all the subsequent scientific discussions, data modeling, and computational approaches.

Prerequisites

Assumed prior knowledge includes: Completed undergraduate study with quantitative STEM exposure, some quantitative training, programming experience, and high-level of energy and motivation to learn. Preinstalled R and RStudio on user local client computer.

Vision

This course is based on active-learning and integrates driving motivational challenges with mathematical foundations, computational statistics, and modern scientific inference.

Values

The training aims to provide effective, reliable, reproducible, and transformative data-driven discovery supporting open-science.

Strategic priorities

Trainees will develop scientific intuition, computational skills, and data-wrangling abilities to tackle Big biomedical and health data problems. Instructors will provide well-documented R-scripts and software recipes implementing atomic data-filters as well as complex end-to-end predictive big data analytics solutions.

Outcomes

Upon successful completion of this course, participants are expected to have moderate competency in at least two of each of the three competency areas: Algorithms and Applications, Data Management, and Analysis Methods. Specifically, participants will get end-to-end R-protocols, gain ML/AI algorithm knowledge, explore data validation, wrangling, and visualization, experiment with statistical inference and model-free Machine Learning tools.

Capstone Project

Following the first two days of instruction, each participant is expected to work for the next two weeks on designing, implementing, and presenting a capstone project. This hands-on project experience will provide interactive-learning to reinforce some of the DSPA concepts. Each participant can choose their own study and dataset, or utilize some of the provided case-studies data. If, and when necessary, 2 or 3 people can team up on a project.

  • Capstone Template: The supporting DSPA Canvas site includes 2 specific exemplary datasets (economic and biomedical), among many dozens of other case-studies. There are also two R markdown (Rmd) templates, and their corresponding HTML outputs, included on the canvas site. Each participant will customize the Rmd templates to fit their project design needs, analytical protocol, and study goals.
  • Expectations: The R markdown electronic notebook will capture the entire study, from conceptualizing the study, designing the experiments, data retrieval, wrangling, harmonization, preprocessing, and visualization, to execution of the workflow protocol, reporting and result presentation on Day 3 of the course. In the spirit of open science, transparent discoveries, scientific rigor, reproducibility, and team-cooperation, all Rmd notebooks must be self-contained. We will discuss in class how the entire study can be automatically compiled into PDF, HTML, DOCX or other formatted reports, by knitting (knitr) the Rmd electronic notebook.
  • Presentations: On day 3, each participant will have 5-minutes to present their capstone project, plus 5-minutes for community input, feedback, suggestions, and constructive recommendations. We'll probably proceed in the order of the listed participants. Everyone is expected to be present and actively engaged throughout the course and the capstone presentations.
  • Use of sensitive data: If you have sensitive data that you want to use in your capstone project (e.g., PHI, IP, or other protected information), please desensitize your protocol, so that your R markdown notebook and the report you present do not compromise individual privacy, organizational property, or violate various local or international regulations (e.g., GDPR, FERPA, HIPPA). You can use the DataSifter or other protocols to obfuscate and desensitize your dataset.
