Attentive Illumination Decomposition Model for Multi-Illuminant White Balancing

no code implementations28 Feb 2024 Dongyoung Kim, Jinwoo Kim, Junsang Yu, Seon Joo Kim

White balance (WB) algorithms in many commercial cameras assume single and uniform illumination, leading to undesirable results when multiple lighting sources with different chromaticities exist in the scene.

Learning Probabilistic Symmetrization for Architecture Agnostic Equivariance

1 code implementation NeurIPS 2023 Jinwoo Kim, Tien Dat Nguyen, Ayhan Suleymanzade, Hyeokjun An, Seunghoon Hong

In contrary to equivariant architectures, we use an arbitrary base model such as an MLP or a transformer and symmetrize it to be equivariant to the given group by employing a small equivariant network that parameterizes the probabilistic distribution underlying the symmetrization.

Transformers meet Stochastic Block Models: Attention with Data-Adaptive Sparsity and Cost

1 code implementation27 Oct 2022 Sungjun Cho, Seonwoo Min, Jinwoo Kim, Moontae Lee, Honglak Lee, Seunghoon Hong

The forward and backward cost are thus linear to the number of edges, which each attention head can also choose flexibly based on the input.
