Lecture Details

[Day 1, Topic 1] Introduction to Machine Learning

This module begins by introducing what can be achieved today with Machine Learning. It will then overview the basics of supervised learning. In particular, it will discuss the notions of features, linear predictors, loss minimization, and stochastic gradient descent. It will do so within the context of a typical machine learning workflow that entails the collection of data, the learning, and the validation prior to a practical deployment of model predictors.

[Day 1, Topic 2] Social Network Analysis

Social media has become an indispensable communication tool giving rise to global online social networks. Analyzing social media data helps study the properties and behaviors of individuals, communities, and organizations and advance our understanding of social and cultural dynamics through the lens of modern information and communication technologies (ICTs). The knowledge thus extracted helps in harnessing business intelligence and guides decision making. The course will introduce basic social science concepts, theories, and principles relevant to guide model development, data analysis, and inference making. Data collection from social media sites using crawlers and APIs will be discussed. Interfacing the collected data with visualization and analytical tools will be taught to enable better understanding of data and extracting actionable knowledge. Specifically, social network analysis (SNA) techniques will be taught to meaningfully study the data to identify trends, leaders, and groups. These skills can be used to analyze social media data about products, services, campaigns, markets, events, customers, and employees; segment audience by geography or demographics, influencers, recommenders or detractors; and measure social media activities. Case-studies will be discussed to demonstrate the impact even the most basic analyses could afford.

[Day 2, Topic 4] AI in Smart Health: Cardiovascular Imaging and Data Analysis

Cardiovascular medicine generates a plethora of biomedical, clinical and imaging data as part of patient care delivery. Often these data are stored in diverse data repositories which are not readily utilizable for cardiovascular research due to challenges in automated abstraction and manual curation technical competency. Moreover, clinical decisions for patient care from data are limited to visual and quantitative assessment of cardiac structure and function. However, it is becoming evident that the best way to make decisions on the basis of data is through the application of machine learning and artificial intelligence techniques.

Application of traditional machine learning techniques in cardiology, however, are challenging due to the inherent difficulties in understanding large, high-dimensional and, often, noisy unlabeled data. Specifically, traditional machine learning techniques, despite their effectiveness, still have some drawbacks which might introduce unwanted biases (e.g., specific metrics). Often the success of the machine learning model depends on how well it fits the underlying data. In this lecture, we will introduce a new approach of understanding patterns in the data that are associated with its shape, topological data analysis (TDA). TDA provides a general framework for analyzing data to identify groups or patterns that provide more information about structure in the logical relationships among phenotypic, demographic, and disease variables which can then be combined with traditional machine learning approaches. This lecture will give students a theoretical/fundamental and practical experience on TDA in particular what it is, how it works, and how it can work with machine learning methods to get better results than are possible by either technique individually.

Course objectives:
  • Teaching participant the basic underlying theory behind topological data analysis.
  • Teaching participant how to identify a way that highlights high value segments of the data through TDA using a demo.

[Day 2, Topic 5] AI, Privacy & Fairness in Healthcare

The remarkable development of AI in healthcare domain presents obvious privacy and fairness issues, when data analytics models are built on users’ personal and highly sensitive data, e.g., clinical records, user profiles, and biomedical images. In this talk, we start with the general problem of privacy, medical ethics, and their significance in digital health. We then concentrate on research of differential privacy preserving machine learning. Differential privacy ensures that the adversary cannot infer any information about any particular record with high confidence (controlled by a privacy budget) from the released learning models. We introduce the concept of differential privacy and present several mechanisms, including Laplace mechanism, exponential mechanism, input perturbation, and functional perturbation, that have been developed to enforce differential privacy in machine learning models, and discuss how to apply and adapt those mechanism to preserve differential privacy in deep learning models. Next we focus on fairness aware machine learning as decision models can cause discrimination against individuals and groups beyond damages to privacy. We introduce a unified causal modeling and counterfactual inference based framework to capture and measure discrimination accurately and present challenges and several efficient algorithms to discover and remove various types of discrimination such as direct/indirect and individual/group/system discrimination from historical training datasets as well as predictive models while preserving data utility. Some recent work of fairness aware generative adversarial networks and fair recommendation will also be covered. We conclude the talk with challenges of building trustworthy AI systems in digital health.
