Dynamic and Super-Personalized Media Ecosystem Driven by Generative AI: Unpredictable Plays Never Repeating The Same

no code implementations19 Feb 2024 Sungjun Ahn, Hyun-Jeong Yim, Youngwan Lee, Sung-Ik Park

This paper introduces a media service model that exploits artificial intelligence (AI) video generators at the receive end.

KOALA: Self-Attention Matters in Knowledge Distillation of Latent Diffusion Models for Memory-Efficient and Fast Image Synthesis

no code implementations7 Dec 2023 Youngwan Lee, KwanYong Park, Yoorhim Cho, Yong-Ju Lee, Sung Ju Hwang

We hope that due to its balanced speed-performance tradeoff, our KOALA models can serve as a cost-effective alternative to SDXL in resource-constrained environments.

Diverse Temporal Aggregation and Depthwise Spatiotemporal Factorization for Efficient Video Classification

1 code implementation1 Dec 2020 Youngwan Lee, Hyung-Il Kim, Kimin Yun, Jinyoung Moon

By using the proposed temporal modeling method (T-OSA), and the efficient factorized component (D(2+1)D), we construct two types of VoV3D networks, VoV3D-M and VoV3D-L.

Moreover, we further improved SWA to be adequate to adversarial training.

CenterMask: Real-Time Anchor-Free Instance Segmentation

1 code implementation CVPR 2020 Youngwan Lee, Jongyoul Park

We propose a simple yet efficient anchor-free instance segmentation, called CenterMask, that adds a novel spatial attention-guided mask (SAG-Mask) branch to anchor-free one stage object detector (FCOS) in the same vein with Mask R-CNN.
