A Deep Learning Approach for Dynamic Balance Sheet Stress Testing
Anastasios Petropoulos, Vassilis Siakoulis, Konstantinos P. Panousis +2
In the aftermath of the financial crisis, supervisory authorities have considerably altered the mode of operation of financial stress testing. Despite these efforts, significant co…
Local Competition and Uncertainty for Adversarial Robustness in Deep Learning
Antonios Alexos, Konstantinos P. Panousis, Sotirios Chatzis
This work attempts to address adversarial robustness of deep networks by means of novel learning arguments. Specifically, inspired from results in neuroscience, we propose a local…
Variational Conditional Dependence Hidden Markov Models for Skeleton-Based Action Recognition
Konstantinos P. Panousis, Sotirios Chatzis, Sergios Theodoridis
Hidden Markov Models (HMMs) comprise a powerful generative approach for modeling sequential data and time-series in general. However, the commonly employed assumption of the depend…
