APT Attack Analysis in SCADA Systems

2018 · MATEC Web of Conferences

SCADA (Supervisory Control and Data Acquisition) systems play a significant role in ICS (Industrial Control System). Safety, security and stable operation is crucial to the SCADA system. However, SCADA system currently faces many security threats, …

A Theory of Unsupervised Speech Recognition

2023 · arXiv (Cornell University)

Unsupervised speech recognition (ASR-U) is the problem of learning automatic speech recognition (ASR) systems from unpaired speech-only and text-only corpora. While various algorithms exist to solve this problem, a theoretical framework is missing from studying …

Unsupervised Speech Recognition with N-Skipgram and Positional Unigram Matching

2023 · arXiv (Cornell University)

Training unsupervised speech recognition systems presents challenges due to GAN-associated instability, misalignment between speech and text, and significant memory demands. To tackle these challenges, we introduce a novel ASR system, ESPUM. This system harnesses the …

Byzantine-Robust Federated Learning through Dynamic Clustering

2023

Federated learning enables distributed and collaborative learning among multiple participants while protecting their privacy. However, due to its distributed nature, federated learning is vulnerable to Byzantine attacks. These attacks can poison the data or directly …

XNMT: The eXtensible Neural Machine Translation Toolkit

2018 · arXiv (Cornell University)

This paper describes XNMT, the eXtensible Neural Machine Translation toolkit. XNMT distin- guishes itself from other open-source NMT toolkits by its focus on modular code design, with the purpose of enabling fast iteration in research …
