Lecture Details
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.

He holds a D.Eng. degree in Electronics Engineering from the University of Padua, Italy, and a M.S. and a Ph.D. in Computer Science, both from UCLA.
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.

Introduction to Deep Learning Architectures
This lecture provides a broad introduction to the basic concept of the classical neural networks (NN) and its current evolution to deep learning (DL) technology. The primary goal of this lecture is to introduce the well-known deep learning architectures and their applications. This lecture will describe the history of neural networks and its progress to current deep learning technology. It covers several deep learning architectures such the classical multi-layer feed forward neural networks, multi-layer auto-encoders, and examples of popular convolutional neural network-based architectures such as AlexNet, VGGNet, GooGleNet (inception modules), and ResNet. Advanced architectures such as Siamese deep networks, coupled neural networks will also be covered.

Privacy, Fairness, and Explainable AI
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.

Hands-on with Practical AI platforms
This session will focus on the use three platforms or frameworks for big data science and artificial intelligence. This will be a hands-on session and participants will examine and use the discussed frameworks to analyze large datasets and experiment with machine learning methodologies. As this is a hands-on session, participants will need to have access to a laptop or desktop computer (rather than a phone or Ipad). Also, since some of the activities will use tools from Google, each participant should have a Google account (such as gmail).
