Explicit Dropout: Deterministic Regularization for Transformer Architectures

Vidhi Agrawal, Illia Oleksiienko, Alexandros Iosifidis

Dropout is a widely used regularization technique in deep learning, but its effects are typically realized through stochastic masking rather than explicit optimization objectives.…

Delay Bound Relaxation with Deep Learning-based Haptic Estimation for Tactile Internet

Georgios Kokkinis, Alexandros Iosifidis, Qi Zhang

Haptic teleoperation typically demands sub-millisecond latency and ultra-high reliability (99.999%) in Tactile Internet. At a 1 kHz haptic signal sampling rate, this translates int…

Learning hidden cascades via classification

Derrick Gilchrist Edward Manoharan, Anubha Goel, Alexandros Iosifidis +2

The spreading dynamics in social networks are often studied under the assumption that individuals' statuses, whether informed or infected, are fully observable. However, in many re…

LOBERT: Generative AI Foundation Model for Limit Order Book Messages

Eljas Linna, Kestutis Baltakys, Alexandros Iosifidis +1

Modeling the dynamics of financial Limit Order Books (LOB) at the message level is challenging due to irregular event timing, rapid regime shifts, and the reactions of high-frequen…

xHAP: Cross-Modal Attention for Haptic Feedback Estimation in the Tactile Internet

Georgios Kokkinis, Alexandros Iosifidis, Qi Zhang

The Tactile Internet requires ultra-low latency and high-fidelity haptic feedback to enable immersive teleoperation. A key challenge is to ensure ultra-reliable and low-latency tra…
