Towards Secure and Efficient Payment Channels
Georgia Avarikioti, Felix Laufenberg, Jakub Sliwinski +2
Micropayment channels are the most prominent solution to the limitation on transaction throughput in current blockchain systems. However, in practice channels are risky because par…
High Dimensional Clustering with -nets
Georgia Avarikioti, Alain Ryser, Yuyi Wang +1
Clustering, a fundamental task in data science and machine learning, groups a set of objects in such a way that objects in the same cluster are closer to each other than to those i…
Algorithmic Blockchain Channel Design
Georgia Avarikioti, Yuyi Wang, Roger Wattenhofer
Payment networks, also known as channels, are a most promising solution to the throughput problem of cryptocurrencies. In this paper we study the design of capital-efficient paymen…
Payment Network Design with Fees
Georgia Avarikioti, Gerrit Janssen, Yuyi Wang +1
Payment channels are the most prominent solution to the blockchain scalability problem. We introduce the problem of network design with fees for payment channels from the perspecti…
MIDI-VAE: Modeling Dynamics and Instrumentation of Music with Applications to Style Transfer
Gino Brunner, Andres Konrad, Yuyi Wang +1
We introduce MIDI-VAE, a neural network model based on Variational Autoencoders that is capable of handling polyphonic music with multiple instrument tracks, as well as modeling th…
Symbolic Music Genre Transfer with CycleGAN
Gino Brunner, Yuyi Wang, Roger Wattenhofer +1
Deep generative models such as Variational Autoencoders (VAEs) and Generative Adversarial Networks (GANs) have recently been applied to style and domain transfer for images, and in…
VC-Dimension Based Generalization Bounds for Relational Learning
Ondrej Kuzelka, Yuyi Wang, Steven Schockaert
In many applications of relational learning, the available data can be seen as a sample from a larger relational structure (e.g. we may be given a small fragment from some social n…
Byzantine Preferential Voting
Darya Melnyk, Yuyi Wang, Roger Wattenhofer
In the Byzantine agreement problem, n nodes with possibly different input values aim to reach agreement on a common value in the presence of t < n/3 Byzantine nodes which represent…
PAC-Reasoning in Relational Domains
Ondrej Kuzelka, Yuyi Wang, Jesse Davis +1
We consider the problem of predicting plausible missing facts in relational data, given a set of imperfect logical rules. In particular, our aim is to provide bounds on the (expect…
Natural Language Multitasking: Analyzing and Improving Syntactic Saliency of Hidden Representations
Gino Brunner, Yuyi Wang, Roger Wattenhofer +1
We train multi-task autoencoders on linguistic tasks and analyze the learned hidden sentence representations. The representations change significantly when translation and part-of-…
