Alternating Objectives Generates Stronger PGD-Based Adversarial Attacks
Nikolaos Antoniou, Efthymios Georgiou, Alexandros Potamianos
Designing powerful adversarial attacks is of paramount importance for the evaluation of -bounded adversarial defenses. Projected Gradient Descent (PGD) is one of the most e…
A Multi-Task BERT Model for Schema-Guided Dialogue State Tracking
Eleftherios Kapelonis, Efthymios Georgiou, Alexandros Potamianos
Task-oriented dialogue systems often employ a Dialogue State Tracker (DST) to successfully complete conversations. Recent state-of-the-art DST implementations rely on schemata of d…
Regotron: Regularizing the Tacotron2 architecture via monotonic alignment loss
Efthymios Georgiou, Kosmas Kritsis, Georgios Paraskevopoulos +3
Recent deep learning Text-to-Speech (TTS) systems have achieved impressive performance by generating speech close to human parity. However, they suffer from training stability issu…
MMLatch: Bottom-up Top-down Fusion for Multimodal Sentiment Analysis
Georgios Paraskevopoulos, Efthymios Georgiou, Alexandros Potamianos
Current deep learning approaches for multimodal fusion rely on bottom-up fusion of high and mid-level latent modality representations (late/mid fusion) or low level sensory inputs…
