Creating New Voices using Normalizing Flows

no code implementations22 Dec 2023 Piotr Bilinski, Thomas Merritt, Abdelhamid Ezzerg, Kamil Pokora, Sebastian Cygert, Kayoko Yanagisawa, Roberto Barra-Chicote, Daniel Korzekwa

As there is growing interest in synthesizing voices of new speakers, here we investigate the ability of normalizing flows in text-to-speech (TTS) and voice conversion (VC) modes to extrapolate from speakers observed during training to create unseen speaker identities.

Technical Report for ICCV 2023 Visual Continual Learning Challenge: Continuous Test-time Adaptation for Semantic Segmentation

no code implementations20 Oct 2023 Damian Sójka, Yuyang Liu, Dipam Goswami, Sebastian Cygert, Bartłomiej Twardowski, Joost Van de Weijer

Each sequence is composed of 401 images and starts with the source domain, then gradually drifts to a different one (changing weather or time of day) until the middle of the sequence.

AR-TTA: A Simple Method for Real-World Continual Test-Time Adaptation

no code implementations18 Sep 2023 Damian Sójka, Sebastian Cygert, Bartłomiej Twardowski, Tomasz Trzciński

Test-time adaptation is a promising research direction that allows the source model to adapt itself to changes in data distribution without any supervision.

Looking through the past: better knowledge retention for generative replay in continual learning

1 code implementation18 Sep 2023 Valeriya Khan, Sebastian Cygert, Kamil Deja, Tomasz Trzciński, Bartłomiej Twardowski

We notice that in VAE-based generative replay, this could be attributed to the fact that the generated features are far from the original ones when mapped to the latent space.

Generalized Continual Category Discovery

no code implementations23 Aug 2023 Daniel Marczak, Grzegorz Rypeść, Sebastian Cygert, Tomasz Trzciński, Bartłomiej Twardowski

However, these settings are not well aligned with real-life scenarios, where a learning agent has access to a vast amount of unlabeled data encompassing both novel (entirely unlabeled) classes and examples from known classes.

Adapt Your Teacher: Improving Knowledge Distillation for Exemplar-free Continual Learning

1 code implementation18 Aug 2023 Filip Szatkowski, Mateusz Pyla, Marcin Przewięźlikowski, Sebastian Cygert, Bartłomiej Twardowski, Tomasz Trzciński

In this work, we investigate exemplar-free class incremental learning (CIL) with knowledge distillation (KD) as a regularization strategy, aiming to prevent forgetting.

Robust Object Detection with Multi-input Multi-output Faster R-CNN

no code implementations25 Nov 2021 Sebastian Cygert, Andrzej Czyzewski

In this work, a generalization of the MIMO approach is applied to the task of object detection using the general-purpose Faster R-CNN model.

Closer Look at the Uncertainty Estimation in Semantic Segmentation under Distributional Shift

no code implementations31 May 2021 Sebastian Cygert, Bartłomiej Wróblewski, Karol Woźniak, Radosław Słowiński, Andrzej Czyżewski

While recent computer vision algorithms achieve impressive performance on many benchmarks, they lack robustness - presented with an image from a different distribution, (e. g. weather or lighting conditions not considered during training), they may produce an erroneous prediction.

Robustness in Compressed Neural Networks for Object Detection

no code implementations10 Feb 2021 Sebastian Cygert, Andrzej Czyżewski

It was further shown that while data imbalance methods brought only a slight increase in accuracy for the baseline model (without compression), the impact was more striking at higher compression rates for the structured pruning.
