UNICON: A unified framework for behavior-based consumer segmentation in e-commerce
Manuel Dibak, Vladimir Vlasov, Nour Karessli +5
Data-driven personalization is a key practice in fashion e-commerce, improving the way businesses serve their consumers needs with more relevant content. While hyper-personalizatio…
DIET: Lightweight Language Understanding for Dialogue Systems
Tanja Bunk, Daksh Varshneya, Vladimir Vlasov +1
Large-scale pre-trained language models have shown impressive results on language understanding benchmarks like GLUE and SuperGLUE, improving considerably over other pre-training m…
Where is the context? -- A critique of recent dialogue datasets
Johannes E. M. Mosig, Vladimir Vlasov, Alan Nichol
Recent dialogue datasets like MultiWOZ 2.1 and Taskmaster-1 constitute some of the most challenging tasks for present-day dialogue models and, therefore, are widely used for system…
Dialogue Transformers
Vladimir Vlasov, Johannes E. M. Mosig, Alan Nichol
We introduce a dialogue policy based on a transformer architecture, where the self-attention mechanism operates over the sequence of dialogue turns. Recent work has used hierarchic…
Few-Shot Generalization Across Dialogue Tasks
Vladimir Vlasov, Akela Drissner-Schmid, Alan Nichol
Machine-learning based dialogue managers are able to learn complex behaviors in order to complete a task, but it is not straightforward to extend their capabilities to new domains.…
Thermodynamics of network model fitting with spectral entropies
Carlo Nicolini, Vladimir Vlasov, Angelo Bifone
An information theoretic approach inspired by quantum statistical mechanics was recently proposed as a means to optimize network models and to assess their likelihood against synth…
Hub induced remote synchronization and desynchronization in complex networks of Kuramoto oscillators
Vladimir Vlasov, Angelo Bifone
The concept of "remote synchronization" (RS) was introduced in [Phys. Rev. E 85, 026208 (2012)], where synchronization in a star network of Stuart-Landau oscillators was investigat…
Dynamics of weakly inhomogeneous oscillator populations: Perturbation theory on top of Watanabe-Strogatz integrability
Vladimir Vlasov, Michael Rosenblum, Arkady Pikovsky
As has been shown by Watanabe and Strogatz (WS) [Phys. Rev. Lett., 70, 2391 (1993)], a population of identical phase oscillators, sine-coupled to a common field, is a partially int…
Star-type oscillatory networks with generic Kuramoto-type coupling: a model for "Japanese drums synchrony"
Vladimir Vlasov, Arkady Pikovsky, Elbert E. N. Macau
We analyze star-type networks of phase oscillators by virtue of two methods. For identical oscillators we adopt the Watanabe-Strogatz approach, that gives full an- alytical descrip…
Explosive Synchronization is Discontinuous
Vladimir Vlasov, Yong Zou, Tiago Pereira
Spontaneous explosive is an abrupt transition to collective behavior taking place in heterogeneous networks when the frequencies of the nodes are positively correlated to the node…
Synchronization transitions in ensembles of noisy oscillators with bi-harmonic coupling
Vladimir Vlasov, Maxim Komarov, Arkady Pikovsky
We describe synchronization transitions in an ensemble of globally coupled phase oscillators with a bi-harmonic coupling function, and two sources of disorder - diversity of intrin…
Synchronization of oscillators in a Kuramoto-type model with generic coupling
Vladimir Vlasov, Elbert E. N. Macau, Arkady Pikovsky
We study synchronization properties of coupled oscillators on networks that allow description in terms of global mean field coupling. These models generalize the standard Kuramoto-…
Synchronization of a Josephson junction array in terms of global variables
Vladimir Vlasov, Arkady Pikovsky
We consider an array of Josephson junctions with a common LCR-load. Application of the Watanabe-Strogatz approach [Physica D, v. 74, p. 197 (1994)] allows us to formulate the dynam…
