Taras Khakhulin

I am a Ph.D. student at Skoltech advised by Victor Lempitsky and research engineer at Samsung AI Center. I try to synthesize things that people currently cannot. During my studies, I have contributed to 3D representations, image synthesis, and human avatars. I hope that soon we will be able to scan the whole world, including ourselves to improve the immersive communications.

Prior to that, I investigate the application of reinforcement learning for discrete optimization under the supervision of Prof. Ivan Oseledets. Earlier, I was a part of the DeepPavlov project, where we studied word representations for text with missplellings.

Realistic One-shot Mesh-based Head Avatars
Taras Khakhulin, Vanessa Sklyarova, Victor Lempitsky, Egor Zakharov
ECCV, 2022
project page / arXiv / bibtex

Create an animatable avatar just from a single image with coarse hair mesh and neural rendering. We learn head geometry and rendering together with supreme quality in a cross-person reenactment.

One-shot high-resolution avatars with latent poses for cross-reenactment.

Stereo Magnification with Multi-Layer Images

CVPR, 2022
project page / arXiv / dataset / blog / bibtex

The scene can be represented as a set of semi-transparent mesh layers from just stereo pair without loss of the quality. This representation allows effortless estimation and fast rendering. Additionaly, we published a dataset with occluded region - SWORD - for novel view synthesis.

Image Generators with Conditionally-Independent Pixel Synthesis

CVPR, 2021 (Oral Presentation)
arXiv / code / samples / blog / bibtex

Our generator produce images without any spatial convolutions. Each pixel synthesized separetly conditioned on noise vector. We investigate properties of such generator and propose several applications (e.g. super-res, foveated rendering).

Learning Elimination Ordering for Tree Decomposition Problem
Taras Khakhulin Roman Schutski, Ivan Oseledets
Learning Meets Combinatorial Algorithms, NeurIPS Workshop , 2020
presentation / paper / arXiv / bibtex

We propose a learning heuristic with RL for real-world combinatorial problem on graphs. Suprisingly, we can easily estimate universal policy which can be scaled across different graphs.

Our generator produce images without any spatial convolutions. Each pixel synthesized separetly conditioned on noise vector.

td Simple heuristics for efficient parallel tensor contraction and quantum circuit simulation
Roman Schutski, Dmitry Kolmakov, Taras Khakhulin, Ivan Oseledets
Physical Review A, 2020
arXiv / bibtex

The heuristic approach based on tree decomposition to relax the contraction of tensor networks using probabilistic graphical models and applied for random quantum circuits.

rove Robust word vectors: context-informed embeddings for noisy texts
Valentin Malykh, Varvara Logacheva, Taras Khakhulin
Workshop on Noisy User-generated Text at EMNLP, 2018
paper / bibtex

We suggest a new language-independent architecture of robust word vectors (RoVe). It is designed to alleviate the issue of typos, which are common in almost any user-generated content, and hinder automatic text processing. Our model allows it to deal with unseen word forms in morphologically rich languages before contextualized language models.
