SEED: Towards More Accurate Semantic Evaluation for Visual Brain Decoding

no code implementations9 Mar 2025 Juhyeon Park, Peter Yongho Kim, Jiook Cha, Shinjae Yoo, Taesup Moon

Through the evaluation of existing visual brain decoding models, we further reveal that crucial information is often lost in translation, even in state-of-the-art models that achieve near-perfect scores on existing metrics.

AesFA: An Aesthetic Feature-Aware Arbitrary Neural Style Transfer

1 code implementation10 Dec 2023 Joonwoo Kwon, Sooyoung Kim, Yuewei Lin, Shinjae Yoo, Jiook Cha

The primary idea is to decompose the image via its frequencies to better disentangle aesthetic styles from the reference image while training the entire model in an end-to-end manner to exclude pre-trained models at inference completely.

SwiFT: Swin 4D fMRI Transformer

1 code implementation NeurIPS 2023 Peter Yongho Kim, Junbeom Kwon, Sunghwan Joo, Sangyoon Bae, DongGyu Lee, Yoonho Jung, Shinjae Yoo, Jiook Cha, Taesup Moon

To address this challenge, we present SwiFT (Swin 4D fMRI Transformer), a Swin Transformer architecture that can learn brain dynamics directly from fMRI volumes in a memory and computation-efficient manner.

GANBERT: Generative Adversarial Networks with Bidirectional Encoder Representations from Transformers for MRI to PET synthesis

no code implementations10 Aug 2020 Hoo-chang Shin, Alvin Ihsani, Swetha Mandava, Sharath Turuvekere Sreenivas, Christopher Forster, Jiook Cha, Alzheimer's Disease Neuroimaging Initiative

Synthesizing medical images, such as PET, is a challenging task due to the fact that the intensity range is much wider and denser than those in photographs and digital renderings and are often heavily biased toward zero.
