Title
Strengthening Machine Learning-based Intrusion Detection Systems in Adversarial Environments
Abstract
Machine learning (ML) has witnessed remarkable advancements in recent years, demonstrating its effectiveness in a wide array of applications, including intrusion detection systems (IDS). However, when operating in adversarial environments, ML-based systems are susceptible to a range of attacks. In this talk, we will discuss technologies designed to strengthen ML-based IDS. On one hand, we explore methods for enhancing the performance and robustness of IDS. We introduce a contrastive learning-based approach that builds highly discriminative IDS, enabling more effective differentiation between normal and malicious activities. On the other hand, we develop efficient security mechanisms to counter common adversarial attacks. This includes an adversarial example (AE) detector designed to identify suspicious inputs at the model testing time, filtering out potential AEs, and a robust model evaluation method that leverages latent space representations to build resiliency in model aggregation against model poisoning attacks in federated learning. This talk will share the outcomes of our research in fortifying ML-based IDS, shedding light on the advancements and techniques that can enhance the security and robustness of these systems in adversarial environments.

Title
Variable-capacity scheduling
Abstract
Future data and HPC centers are expected to have a highly variable computing potential: the total capacity, cost, and nature (green or brown) of available power will change over time by large fractions, with or without prior notice.
In this talk, we first review state-of-the art techniques and optimization metrics for resource management and job allocation. Then we formulate the new challenges and opportunities that come with scheduling on variable-capacity platforms. We survey several strategies, some old and some new, to address these challenges. RESIZING (changing the runtime of applications, and hence their scheduling profile) and REASSIGNING (changing the mapping of jobs to account for machine volatility) are key to improving efficiency. We also discuss the impact of workload flexibility and rate/magnitude of resource variation.

Title
Edge-Cloud Networks for Efficient AI/ML Implementations
Abstract
Edge-cloud networks connect a wide range of systems and devices, ranging from large data centers to small IoT devices. The potential advantages of adopting edge and cloud networking include the quick adaptation of new technologies, including a faster rollout and adoption of software and feature updates, as well as better management of various resources, including network and edge devices. This talk provides an overview of some challenges in efficient support for running AI/ML algorithms in edge-cloud networks. Our focus is on low latency, connectivity, and local data processing while still achieving efficiency. We will look at two specific examples of AI/ML implementations: one is the optimal offloading of AI/ML code from IoT/edge devices to the cloud, and the other is exploring network topology and connectivity for efficient decentralized federated learning.
