Machine Learning and Cryptocurrency Markets

Invited talk in Special Session on Advances in Machine Learning for Finance

Nino Antulov-Fantulin, PhD

ETH Zurich, Switzerland


In this talk, we present the research around “Cryptocurrency and blockchain systems”. In particular, we analyse, three different sources of data originating from (i) blockchains, (ii) exchange office, and (iii) news data. In the first part, we study the possibility of inferring early warning indicators for periods of extreme bitcoin price volatility using features obtained from the Bitcoin daily transaction graphs. In the second part, we show the temporal mixture models capable of adaptively exploiting both volatility history and order book features. Our temporal mixture model enables to decipher time-varying effect of order book features on the volatility. In the last part, we focus on cryptocurrency news. In order to track popular news in real-time, we (a) match news from the web with tweets from social media,(b) track their intraday tweet activity and (c) explore different machine learning models for predicting the number of article mentions on Twitter after its publication.

Advancing optical communication and measurement systems using machine learning

Darko Zibar, PhD

DTU Fotonik, Technical University of Denmark, Denmark


According to the recent data traffic predictions, current optical communication systems, operating in the C–band only, will not be able to satisfy future data rate demands. A viable and long–term solution would be to employ systems operating in multiple bands (O+E+S+C+L) and make usage of the spatial division multiplexing (SDM) (multi–core and multi–mode). Designing optimal signaling, amplification and detection schemes, for such systems, will be challenging due to the high system complexity. Finally, performing system optimization in terms of channel power and bandwidth allocation, as well as modulation format selection, will become difficult using standard tools that rely on analytical or semi–analytical models. What will complicate the matter even further is the focus on providing a secure way of transmitting information using quantum communication. This will require a coexistence and management of classical and quantum channels in the same optical network. As quantum signals have in general significantly, lower powers compared to the signals in classical communication, the reception of quantum signals is more challenging, making a strong case for having intelligent optical receivers that can receive and even distinguish between classical and quantum signals. The field of machine learning (ML) can provide useful tools to address the aforementioned challenges. This is because ML techniques excel at: 1) learning highly–complex input–output mappings which allows for system optimization, 2) learning signaling and detection schemes for complex channels or for channels where analytical models are not available and 3) performing ultra–sensitive signal detection. In this talk, it will be shown how machine learning can enable design of ultrawide-band optical amplifiers, perform constellation shaping over the nonlinear fibre optic channel and enable ultra-sensitive measurements of optical phase that approach the quantum limit.
