Unleashing and Speeding Up Readers in Atomic Object Implementations
(Springer International Publishing, 2019)Providing efficient emulations of atomic read/write objects in asynchronous, crash-prone, message-passing systems is an important problem in distributed computing. Communication latency is a factor that typically dominates ...

Self-stabilizing Byzantine Tolerant Replicated State Machine Based on Failure Detectors
(Springer International Publishing, 2018)Byzantine Fault Tolerant (BFT) replication leverages highly available cloud services and can facilitate the implementation of distributed ledgers, e.g., the blockchain. Systems providing BFT State Machine Replication (SMR) ...

Competitive analysis of fundamental scheduling algorithms on a fault-prone machine and the impact of resource augmentation
(2018)Reliable task execution in machines that are prone to unpredictable crashes and restarts is both challenging and of high importance, but not much work exists on the analysis of such systems. We consider the online version ...

Conditional Generative Denoising Autoencoder
(2019)We present a generative denoising autoencoder model that has an embedded data classifier in its architecture in order to take advantage of class-based discriminating features and produce better data samples. The proposed ...

Formalizing and Implementing Distributed Ledger Objects
(2018)Despite the hype about blockchains and distributed ledgers, formal abstractions of these objects are scarce1. To face this issue, in this paper we provide a proper formulation of a distributed ledger object. In brief, we ...

Formalizing and Implementing Distributed Ledger Objects
(Springer International Publishing, 2019)Despite the hype about blockchains and distributed ledgers, no formal abstraction of these objects has been proposed (This observation was also pointed out by Maurice Herlihy in his PODC2017 keynote talk). To face this ...

Practically-self-stabilizing virtual synchrony
(2018)The virtual synchrony abstraction was proven to be extremely useful for asynchronous, large-scale, message-passing distributed systems. Self-stabilizing systems can automatically regain consistency after the occurrence of ...

Modular Domain-to-Domain Translation Network
(Springer International Publishing, 2018)We present a method for constructing and training a deep domain-to-domain translation network: two datasets describing the same classes (i.e. the source and target domains) are used to train a deep network that can translate ...

Article
Modular domain-to-domain translation network
(2020)Domain-to-domain translation methods map images from a source domain to corresponding images from a target domain. The two domains contain images from the same classes, but these images look different. Recent approaches ...
