‘Our Team Consists of True Leaders in Their Respective Academic Disciplines
The HSE International Centre of Decision Choice and Analysis studies a wide range of methods for analysing decision-making and possible scenarios for the development of natural, socio-economic, and political phenomena using various mathematical models. The application of advanced mathematical methods to forecasting helps to prevent negative outcomes and avoid erroneous decisions. The HSE News Service spoke to the centre’s director, Prof. Fuad Aleskerov, about its work.

International N5 Symposium ‘Neural Networks and Nonlinearity in Nizhny Novgorod Brings Together Scientists from Russia and Serbia
The International N5 Symposium ‘Neural Networks and Nonlinearity in Nizhny Novgorod’ was held at the Nizhny Novgorod House of Scientists from September 23 to 26. The event was organised by HSE University–Nizhny Novgorod and the Nizhny Novgorod House of Scientists, with the participation of Sberbank and the Institute of Physics Belgrade. The symposium was held for the second time: the first conference took place in 2025 and attracted considerable interest from the academic community.

Signature codes for the A-channel and collusion-secure multimedia fingerprinting codes

P. 3043–3047.
Egorova E., Kabatiansky G. A., Fernandez M., Moon H. L.

We consider collusion-resistant fingerprinting codes for multimedia content. We show that the corresponding IPP-codes may trace all guilty users and at the same time have exponentially many code words. We also establish an equivalence between signature codes for the A-channel and multimedia fingerprinting codes and prove that the rate of the best t-signature codes for A-channel is at least Θ(t-2). Finally, we construct a family of t-signature codes for the A-channel with polynomial decoding complexity and rate Θ(t-3).

On the Maximal Achievable Rate for Signal-Code Construction Based on Interleaved Reed-Solomon Codes for Multiple Access System Over Vector-Disjunctive Channel
Ivanov F., Rybin P., , in: 2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom).: [б.и.], 2018. P. 1–5.
We consider a signal-code construction for a special class of multiple access system over vector-disjunctive channel. This construction is based on interleaved Reed-Solomon codes with collaborative decoding. The considered methods of encoding and decoding on one hand have acceptable complexity for a wide range parameters and on other one a decoding algorithm is able to ...
