Awareness of uncertainty in classification using a multivariate model and multi-views

no code implementations16 Apr 2024 Alexey Kornaev, Elena Kornaeva, Oleg Ivanov, Ilya Pershin, Danis Alukaev

The proposed model regularizes uncertain predictions, and trains to calculate both the predictions and their uncertainty estimations.

FFC-SE: Fast Fourier Convolution for Speech Enhancement

1 code implementation6 Apr 2022 Ivan Shchekotov, Pavel Andreev, Oleg Ivanov, Aibek Alanov, Dmitry Vetrov

The FFC operator allows employing large receptive field operations within early layers of the neural network.

HiFi++: a Unified Framework for Bandwidth Extension and Speech Enhancement

2 code implementations24 Mar 2022 Pavel Andreev, Aibek Alanov, Oleg Ivanov, Dmitry Vetrov

Generative adversarial networks have recently demonstrated outstanding performance in neural vocoding outperforming best autoregressive and flow-based models.

Variational Autoencoder with Arbitrary Conditioning

3 code implementations ICLR 2019 Oleg Ivanov, Michael Figurnov, Dmitry Vetrov

We propose a single neural probabilistic model based on variational autoencoder that can be conditioned on an arbitrary subset of observed features and then sample the remaining features in "one shot".

Adaptive Cardinality Estimation

1 code implementation22 Nov 2017 Oleg Ivanov, Sergey Bartunov

The experimental evaluation shows that this approach significantly increases the quality of cardinality estimation, and therefore increases the DBMS performance for some queries by several times or even by several dozens of times.
