Title: Confluence in Probabilistic Rewriting, Abstract: Driven by the interest of reasoning about probabilistic programming languages, we set out to study a notion of unicity of normal forms for them. To provide a tractable proof method for it, we define a property of distribution confluence which is shown to imply the...

Title: Kernel Robust Bias-Aware Prediction under Covariate Shift, Abstract: Under covariate shift, training (source) data and testing (target) data differ in input space distribution, but share the same conditional label distribution. This poses a challenging machine learning task. Robust Bias-Aware (RBA) prediction pr...

Title: Degeneration in VAE: in the Light of Fisher Information Loss, Abstract: While enormous progress has been made to Variational Autoencoder (VAE) in recent years, similar to other deep networks, VAE with deep networks suffers from the problem of degeneration, which seriously weakens the correlation between the inpu...

Title: Synthesizing Neural Network Controllers with Probabilistic Model based Reinforcement Learning, Abstract: We present an algorithm for rapidly learning controllers for robotics systems. The algorithm follows the model-based reinforcement learning paradigm, and improves upon existing algorithms; namely Probabilisti...

Title: Stealthy Deception Attacks Against SCADA Systems, Abstract: SCADA protocols for Industrial Control Systems (ICS) are vulnerable to network attacks such as session hijacking. Hence, research focuses on network anomaly detection based on meta--data (message sizes, timing, command sequence), or on the state values ...

Title: Beta-rhythm oscillations and synchronization transition in network models of Izhikevich neurons: effect of topology and synaptic type, Abstract: Despite their significant functional roles, beta-band oscillations are least understood. Synchronization in neuronal networks have attracted much attention in recent ye...

Title: Renyi Differential Privacy, Abstract: We propose a natural relaxation of differential privacy based on the Renyi divergence. Closely related notions have appeared in several recent papers that analyzed composition of differentially private mechanisms. We argue that the useful analytical tool can be used as a pri...

Title: Enhancing Quality for VVC Compressed Videos by Jointly Exploiting Spatial Details and Temporal Structure, Abstract: In this paper, we propose a quality enhancement network for Versatile Video Coding (VVC) compressed videos by jointly exploiting spatial details and temporal structure (SDTS). The network consists ...

Title: Discrete CMC surfaces in R^3 and discrete minimal surfaces in S^3. A discrete Lawson correspondence, Abstract: The main result of this paper is a discrete Lawson correspondence between discrete CMC surfaces in R^3 and discrete minimal surfaces in S^3. This is a correspondence between two discrete isothermic surf...
