The Power of Adaptivity in Representation Learning: from Meta-Learning to Federated Learning
Sanjay Shakkottai, IEEE Fellow, Editor-in-Chief of IEEE/ACM Transactions on Networking
The University of Texas at Austin

A central problem in machine learning is as follows: How should we train models using data generated from a collection of clients/environments, if we know that these models will be deployed in a new and unseen environment? In the setting of few-shot learning, two prominent approaches are: (a) develop a modeling framework that is “primed” to adapt, such as Model Adaptive Meta Learning (MAML), or (b) develop a common model using federated learning (such as FedAvg), and then fine tune the model for the deployment environment. We study both these approaches in the multi-task linear representation setting. We show that the reason behind generalizability of the models in new environments trained through either of these approaches is that the dynamics of training induces the models to evolve toward the common data representation among the clients’ tasks. In both cases, the structure of the bi-level update at each iteration (an inner and outer update with MAML, and a local and global update with FedAvg) holds the key — the diversity among client data distributions are exploited via inner/local updates, and induces the outer/global updates to bring the representation closer to the ground-truth. In both these settings, these are the first results that formally show representation learning and derive exponentially fast convergence to the ground-truth representation. This talk is based on joint work with Liam Collins, Hamed Hassani, Aryan Mokhtari, and Sewoong Oh.

Advances in Collaborative Neurodynamic Optimization
Jun Wang, IEEE Fellow, IAPR Fellow, MAE (foreign)
City University of Hong Kong

The past four decades witnessed the birth and growth of neurodynamic optimization, which has emerged as a potentially powerful problem-solving tool for constrained optimization due to its inherent nature of biological plausibility and parallel and distributed information processing. Despite the success, almost all existing neurodynamic approaches a few years ago worked well only for optimization problems with convex or generalized convex functions. Effective neurodynamic approaches to optimization problems with nonconvex functions and discrete variables are rarely available. In this talk, the advances in neurodynamic optimization will be presented. Specifically, In the proposed collaborative neurodynamic optimization framework, multiple neurodynamic optimization models with different initial states are employed for scattered searches. In addition, a meta-heuristic rule in swarm intelligence (such as PSO) is used to reposition neuronal states upon their local convergence to escape local minima toward global optima. Several specific paradigms in this hybrid intelligence framework will be delineated for multi-objective and mixed-integer optimization. Experimental results will be elaborated to substantiate the efficacy of the methodology including an IoT-based application for distributed chiller loading.

Blockchain-enabled High-confidence Internet of Things
Xiuzhen Cheng, IEEE Fellow
Shandong University

High-Confidence Computing (HCC) relies on interdisciplinary methodologies to realize secure and trusted software, precise and process-traceable algorithms, and self-evolving designs that can adapt to new environments and support new applications. Internet of Things (IoT) systems possessing HCC properties can provide collaborative services that are otherwise impossible as security, traceability, accountability, reliability, robustness, extensibility, adaptivity, and self-evolution are all desirable and equally-important properties of modern connected systems such as smart cities. This talk intends to answer the following questions: what is high-confidence computing and how to realize high-confidence IoT via blockchain technology. We will introduce an architecture to demonstrate our exploratory studies regarding how to integrate state-of-the-art techniques to build a blockchain-enabled high-confidence IoT and present our own effort towards its realization. Open research challenges will also be discussed.
