Solving Black-Box Optimization Challenge via Learning Search Space Partition for Local Bayesian Optimization

1 code implementation18 Dec 2020 Mikita Sazanovich, Anastasiya Nikolskaya, Yury Belousov, Aleksei Shpilman

Black-box optimization is one of the vital tasks in machine learning, since it approximates real-world conditions, in that we do not always know all the properties of a given system, up to knowing almost nothing but the results.

MineRL Diamond 2021 Competition: Overview, Results, and Lessons Learned

no code implementations17 Feb 2022 Anssi Kanervisto, Stephanie Milani, Karolis Ramanauskas, Nicholay Topin, Zichuan Lin, Junyou Li, Jianing Shi, Deheng Ye, Qiang Fu, Wei Yang, Weijun Hong, Zhongyue Huang, Haicheng Chen, Guangjun Zeng, Yue Lin, Vincent Micheli, Eloi Alonso, François Fleuret, Alexander Nikulin, Yury Belousov, Oleg Svidchenko, Aleksei Shpilman

With this in mind, we hosted the third edition of the MineRL ObtainDiamond competition, MineRL Diamond 2021, with a separate track in which we permitted any solution to promote the participation of newcomers.

Authentication of Copy Detection Patterns under Machine Learning Attacks: A Supervised Approach

no code implementations23 Jun 2022 Brian Pulfer, Roman Chaban, Yury Belousov, Joakim Tutt, Olga Taran, Taras Holotyak, Slava Voloshynovskiy

While Deep Learning (DL) can be used as a part of the authentication system, to the best of our knowledge, none of the previous works has studied the performance of a DL-based authentication system against ML-based attacks on CDP with 1x1 symbol size.

Anomaly localization for copy detection patterns through print estimations

no code implementations29 Sep 2022 Brian Pulfer, Yury Belousov, Joakim Tutt, Roman Chaban, Olga Taran, Taras Holotyak, Slava Voloshynovskiy

Systems based on classical supervised learning and digital templates assume knowledge of fake CDP at training time and cannot generalize to unseen types of fakes.

Printing variability of copy detection patterns

no code implementations11 Oct 2022 Roman Chaban, Olga Taran, Joakim Tutt, Yury Belousov, Brian Pulfer, Taras Holotyak, Slava Voloshynovskiy

Since digital off-set printing represents great flexibility in terms of product personalized in comparison with traditional off-set printing, it looks very interesting to address the above concerns for digital off-set printers that are used by several companies for the CDP protection of physical objects.

Solving the Weather4cast Challenge via Visual Transformers for 3D Images

1 code implementation5 Dec 2022 Yury Belousov, Sergey Polezhaev, Brian Pulfer

Accurately forecasting the weather is an important task, as many real-world processes and decisions depend on future meteorological conditions.

Mathematical model of printing-imaging channel for blind detection of fake copy detection patterns

no code implementations14 Dec 2022 Joakim Tutt, Olga Taran, Roman Chaban, Brian Pulfer, Yury Belousov, Taras Holotyak, Slava Voloshynovskiy

Nowadays, copy detection patterns (CDP) appear as a very promising anti-counterfeiting technology for physical object protection.

TURBO: The Swiss Knife of Auto-Encoders

no code implementations11 Nov 2023 Guillaume Quétant, Yury Belousov, Vitaliy Kinakh, Slava Voloshynovskiy

We present a novel information-theoretic framework, termed as TURBO, designed to systematically analyse and generalise auto-encoding methods.
