On the Fourier analysis in the SO(3) space : EquiLoPO Network

no code implementations24 Apr 2024 Dmitrii Zhemchuzhnikov, Sergei Grudinin

This work suggests the benefits of true rotational equivariance on SO(3) and flexible unconstrained filters enabled by the local activation function, providing a flexible framework for equivariant deep learning on volumetric data with potential applications across domains.

ILPO-NET: Network for the invariant recognition of arbitrary volumetric patterns in 3D

no code implementations28 Mar 2024 Dmitrii Zhemchuzhnikov, Sergei Grudinin

Effective recognition of spatial patterns and learning their hierarchy is crucial in modern spatial data analysis.

6DCNN with roto-translational convolution filters for volumetric data processing

no code implementations26 Jul 2021 Dmitrii Zhemchuzhnikov, Ilia Igashov, Sergei Grudinin

In this work, we introduce 6D Convolutional Neural Network (6DCNN) designed to tackle the problem of detecting relative positions and orientations of local patterns when processing three-dimensional volumetric data.

Spherical convolutions on molecular graphs for protein model quality assessment

1 code implementation16 Nov 2020 Ilia Igashov, Nikita Pavlichenko, Sergei Grudinin

Within the framework of the protein model quality assessment problem, we demonstrate that the proposed spherical convolution method significantly improves the quality of model assessment compared to the standard message-passing approach.

DeepSymmetry : Using 3D convolutional networks for identification of tandem repeats and internal symmetries in protein structures

no code implementations29 Oct 2018 Guillaume Pagès, Sergei Grudinin

Our method is designed to identify tandem repeat proteins, proteins with internal symmetries, symmetries in the raw density maps, their symmetry order, and also the corresponding symmetry axes.

Deep convolutional networks for quality assessment of protein folds

1 code implementation18 Jan 2018 Georgy Derevyanko, Sergei Grudinin, Yoshua Bengio, Guillaume Lamoureux

Additional testing on decoys from the CASP12, CAMEO, and 3DRobot datasets confirms that the network performs consistently well across a variety of protein structures.
