Pixel-Level BPE for Auto-Regressive Image Generation

no code implementations MMMPIE (COLING) 2022 Anton Razzhigaev, Anton Voronov, Andrey Kaznacheev, Andrey Kuznetsov, Denis Dimitrov, Alexander Panchenko

Pixel-level autoregression with Transformer models (Image GPT or iGPT) is one of the recent approaches to image generation that has not received massive attention and elaboration due to quadratic complexity of attention as it imposes huge memory requirements and thus restricts the resolution of the generated images.

The Shape of Learning: Anisotropy and Intrinsic Dimensions in Transformer-Based Models

no code implementations10 Nov 2023 Anton Razzhigaev, Matvey Mikhalchuk, Elizaveta Goncharova, Ivan Oseledets, Denis Dimitrov, Andrey Kuznetsov

In this study, we present an investigation into the anisotropy dynamics and intrinsic dimension of embeddings in transformer architectures, focusing on the dichotomy between encoders and decoders.

Darker than Black-Box: Face Reconstruction from Similarity Queries

1 code implementation27 Jun 2021 Anton Razzhigaev, Klim Kireev, Igor Udovichenko, Aleksandr Petiushko

Several methods for inversion of face recognition models were recently presented, attempting to reconstruct a face from deep templates.

Black-Box Face Recovery from Identity Features

1 code implementation27 Jul 2020 Anton Razzhigaev, Klim Kireev, Edgar Kaziakhmedov, Nurislam Tursynbek, Aleksandr Petiushko

In this work, we present a novel algorithm based on an it-erative sampling of random Gaussian blobs for black-box face recovery, given only an output feature vector of deep face recognition systems.
