Expand-and-Quantize: Unsupervised Semantic Segmentation Using High-Dimensional Space and Product Quantization

no code implementations12 Dec 2023 Jiyoung Kim, Kyuhong Shim, Insu Lee, Byonghyo Shim

In this paper, we propose a novel USS framework called Expand-and-Quantize Unsupervised Semantic Segmentation (EQUSS), which combines the benefits of high-dimensional spaces for better clustering and product quantization for effective information compression.

Depth-Relative Self Attention for Monocular Depth Estimation

no code implementations25 Apr 2023 Kyuhong Shim, Jiyoung Kim, Gusang Lee, Byonghyo Shim

Monocular depth estimation is very challenging because clues to the exact depth are incomplete in a single RGB image.

Beamforming Design with Partial Channel Estimation and Feedback for FDD RIS-Assisted Systems

no code implementations23 Feb 2023 Xiaochun Ge, Shanping Yu, Wenqian Shen, Chengwen Xing, Byonghyo Shim

To acquire the dominating path gain information (DPGI, also regarded as the path gains of selected dominant paths) at the base station (BS), we propose a DPGI estimation and feedback scheme by jointly beamforming design at BS and RIS.

Vision Transformer-based Feature Extraction for Generalized Zero-Shot Learning

no code implementations2 Feb 2023 Jiseob Kim, Kyuhong Shim, Junhan Kim, Byonghyo Shim

In AAM, the correlation between each patch feature and the synthetic image attribute is used as the importance weight for each patch.

Semantic Feature Extraction for Generalized Zero-shot Learning

no code implementations29 Dec 2021 Junhan Kim, Kyuhong Shim, Byonghyo Shim

Key idea of the proposed approach, henceforth referred to as semantic feature extraction-based GZSL (SE-GZSL), is to use the semantic feature containing only attribute-related information in learning the relationship between the image and the attribute.

1 code implementation 2021 IEEE Workshop on Signal Processing Systems (SiPS) 2021 Seokhyeon Choi, Kyuhong Shim, Jungwook Choi, Wonyong Sung, Byonghyo Shim

We propose TernGEMM, a special GEMM library using SIMD instructions for Deep Neural Network (DNN) inference with ternary weights and activations under 8-bit.

Gradual Federated Learning with Simulated Annealing

no code implementations11 Oct 2021 Luong Trung Nguyen, Junhan Kim, Byonghyo Shim

Federated averaging (FedAvg) is a popular federated learning (FL) technique that updates the global model by averaging local models and then transmits the updated global model to devices for their local model update.
