Age-of-Information-Aware Distributed Task Offloading and Resource Allocation in Mobile Edge Computing Networks

no code implementations4 Apr 2024 Minwoo Kim, Jonggyu Jang, Youngchol Choi, Hyun Jong Yang

In existing studies, joint optimization of overall task offloading and UA is seldom considered due to the complexity of combinatorial optimization problems, and in cases where it is considered, linear objective functions such as power consumption are adopted.

Joint Optimization on Uplink OFDMA and MU-MIMO for IEEE 802.11ax: Deep Hierarchical Reinforcement Learning Approach

no code implementations3 Apr 2024 Hyeonho Noh, Harim Lee, Hyun Jong Yang

In unsaturated traffic conditions, considering packet volumes per user introduces a combinatorial problem, requiring the simultaneous optimization of MU-MIMO user selection and RA along the time-frequency-space axis.

Enhancing Sum-Rate Performance in Constrained Multicell Networks: A Low-Information Exchange Approach

no code implementations3 Apr 2024 Youjin Kim, Jonggyu Jang, Hyun Jong Yang

Despite the extensive research on massive MIMO systems for 5G telecommunications and beyond, the reality is that many deployed base stations are equipped with a limited number of antennas rather than supporting massive MIMO configurations.

Patch-MI: Enhancing Model Inversion Attacks via Patch-Based Reconstruction

1 code implementation12 Dec 2023 Jonggyu Jang, Hyeonsu Lyu, Hyun Jong Yang

This approach allows the synthesis of images that are similar to the target dataset distribution, even in cases of dissimilar auxiliary dataset distribution.

Deeper Understanding of Black-box Predictions via Generalized Influence Functions

1 code implementation9 Dec 2023 Hyeonsu Lyu, Jonggyu Jang, Sehyun Ryu, Hyun Jong Yang

However, growing non-convexity and the number of parameters in modern large-scale models lead to imprecise influence approximation and instability in computations.

Privacy-Protection Drone Patrol System based on Face Anonymization

no code implementations29 May 2020 Harim Lee, Myeung Un Kim, Yeongjun Kim, Hyeonsu Lyu, Hyun Jong Yang

These attractive advantages such as high-resolution cameras and mobility can be a double-edged sword, i. e., privacy infringement.

Extreme Low Resolution Activity Recognition with Multi-Siamese Embedding Learning

no code implementations3 Aug 2017 Michael S. Ryoo, Kiyoon Kim, Hyun Jong Yang

This paper presents an approach for recognizing human activities from extreme low resolution (e. g., 16x12) videos.

Privacy-Preserving Human Activity Recognition from Extreme Low Resolution

no code implementations12 Apr 2016 Michael S. Ryoo, Brandon Rothrock, Charles Fleming, Hyun Jong Yang

We introduce the paradigm of inverse super resolution (ISR), the concept of learning the optimal set of image transformations to generate multiple low-resolution (LR) training videos from a single video.
