The Department of Computer Science at SUNY Korea successfully hosted the 2026 AI Summer School Program from July 13 to 17, 2026, on the SUNY Korea campus. The week-long program welcomed 42 student attendees, including students from the Fashion Institute of Technology (FIT), Korea University, and Inha University, bringing together participants from a variety of academic backgrounds to explore how artificial intelligence is being applied in practice today. The program featured a series of lectures delivered by SUNY Korea faculty members alongside invited industry leaders, including CEOs and CTOs from companies actively working with AI. These sessions gave students insight into both the foundations of AI and how it is currently being deployed across different industries, connecting academic concepts to the realities of professional practice. Each day was built around a different theme, allowing participants to encounter a broad view of the field over the course of the week. Beyond the lectures, the program placed strong emphasis on hands-on learning. Students completed a unique exercise each day, drawn from real-life AI applications used by participating companies, giving them direct experience with the tools and workflows practitioners rely on. Participants were divided into five teams and presented their work at the end of every day, sharing their approaches and results with instructors and peers. The daily presentation format encouraged collaboration, gave students immediate feedback, and helped them build confidence in communicating technical work to an audience. Feedback from participants was highly positive. In the post-program survey, the 55 respondents rated their overall experience an average of 4.71 out of 5, while instructor approachability and responsiveness received an average rating of 4.86 out of 5. In addition, 50 respondents said they would recommend the program to a friend or colleague, and 36 reported that the program exceeded their expectations. Participants particularly appreciated the opportunity to learn from both university faculty and industry professionals and to apply what they learned through hands-on projects. Several students also highlighted the value of discovering practical applications of AI beyond the scope of their own academic disciplines, gaining new perspectives on how AI can be used across a wide range of fields. One of the most meaningful outcomes of the week was the demonstration that AI is not the domain of computer science majors alone. Students from a wide range of disciplines successfully applied AI techniques to their own projects and interests, showing that the technology can serve as a practical tool for anyone willing to learn it. Building on the success of this year's AI Summer School, the Department of Computer Science will continue to offer programs that make emerging technologies accessible to students across majors and institutions, fostering innovation, collaboration, and academic excellence.

An undergrad research project that began in the SUNY Korea CS Department has led to a paper accepted at the International Conference on Pattern Recognition, ICPR, a major international venue in pattern recognition and computer vision. Yerin Cheon started the work as part of her CSE487 research project, co-supervised by Prof. François Rameau and Prof. Aruna Balasubramanian from Stony Brook University, who was visiting SUNY Korea at the time. After graduating from SUNY Korea, Yerin joined Stony Brook University for her master’s degree, where she continued developing the project in Prof. Aruna Balasubramanian’s group. The resulting paper, “Dual-Foundation Models for Unsupervised Domain Adaptation,” is the outcome of this continued collaboration. The paper addresses a core challenge in robotics and autonomous vehicles: safely navigating an environment requires understanding the surrounding scene. This is often achieved through semantic segmentation, where each pixel in an image is assigned a category label. Training such deep learning models typically requires large amounts of pixel-level annotation, and the resulting models often do not transfer well to new environments. Unsupervised domain adaptation aims to mitigate that issue, but existing methods still struggle to produce reliable pseudo-labels and robustly align features across domains. Yerin’s approach tackles this limitation by leveraging vision foundation models to improve both pseudo-label refinement and feature alignment. The work is a strong example of how undergraduate research at SUNY Korea can develop into peer-reviewed international publications and continue through collaboration with Stony Brook University.   Research Information · Paper Title: Dual-Foundation Models for Unsupervised Domain Adaptation · Conference: ICPR 2026 · Authors: Yerin Cheon, Aruna Balasubramanian, and Francois Rameau · Project page: https://github.com/ycheon1101/DFUDA · Paper: https://arxiv.org/pdf/2605.03365

  Prof. François Rameau's research team has revealed a major privacy vulnerability in AI-based visual localization models. Their research paper, titled “Seeing Through the Weights: Privacy Leakage in Scene Coordinate Regression,” has been accepted to ECCV 2026, one of the world's most prestigious venues in computer vision and AI. The conference will be held in Malmö, Sweden, from September 8 to 12, 2026. Certain neural network-based visual localization models have long been considered naturally privacy-preserving, since they encode a scene implicitly in their parameters rather than storing images or 3D maps. This work shows that this assumption does not hold: trained models can still leak sensitive information about the environments used to train them.   This research was conducted by Ph.D. student Oleksii Nasypanyi and M.S. student Jaemin Cho, under the supervision of Prof. Utku Ozbulak, Prof. Byungkon Kang, and Prof. François Rameau. The project also reflects a close collaboration within the Incheon Global Campus, bringing together researchers from SUNY Korea, Ghent University Global Campus, and George Mason University Korea.   The team shows that an attacker does not need any images of the target scene to extract information from the model. By simply feeding it random, unrelated images and collecting its outputs, they can gradually reconstruct both the structure and the appearance of the environment the model was trained on. The attack works under different levels of access to the model, from full access to more restricted settings where only its outputs are visible By identifying this vulnerability, the research highlights the need for stronger privacy-aware design and evaluation in AI-based spatial intelligence systems.

  A research paper led by Ph.D. student Si Yong Lee has been accepted for publication at the 2026 International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI), the world's leading international conference in medical AI and computer-assisted healthcare technology, to be held in Strasbourg, France, from September 27 to October 1, 2026. MICCAI is recognized as a top-tier venue with a highly competitive review process, and acceptance represents a significant research achievement. The work was co-authored with graduate students Ryangjin Lee, Hawon Park, and Yoora Kim, and was conducted under the supervision of Prof. Yoon Seok Yang and Prof. Byungkon Kang, reflecting the CS Department's strong culture of close faculty mentorship and student-driven research.   The paper, "SpikeMamba: Spike-Driven State Space Models for Energy-Efficient Biomedical Sequence Modeling," presents the first architecture to bring Mamba state space models entirely into the domain of spiking neural networks, enabling brain-inspired, event-driven computation for biomedical signals such as ECG and EEG. SpikeMamba matched or exceeded the accuracy of state-of-the-art models while consuming over 30 times less energy, opening a practical path toward always-on health monitoring on battery-powered wearable devices and neuromorphic processors such as MindCore.   This achievement highlights the CS Department's growing strength in neuromorphic computing and energy-efficient AI, and its commitment to research with real-world clinical impact.

The event also allowed attendees to discover ongoing research projects and inspired many students to consider participating in research in the future.   The Spring 2026 UROP received overwhelmingly positive feedback from participants, earning an overall satisfaction rating of 4.59 out of 5.0. Attendees particularly appreciated the variety of student presentations and the opportunity to learn about research being conducted across the department. Building on the success of this semester's event, the Department of Computer Science will continue to support undergraduate research initiatives that foster innovation, collaboration, and academic excellence.

Three undergraduate students (Dongyeong Kim, Gilho Kim, and Myeongkjun Kim), together with one Ph.D. student (Si Yong Lee), have published a research paper in IEEE Access, a Q1-ranked international journal, demonstrating an outstanding educational and research achievement. This work was conducted under the supervision of Prof. Yoon Seok Yang and reflects the strong research-oriented educational environment fostered through close faculty mentorship. The research focuses on improving the training and inference efficiency of spiking neural network (SNN)–based object detection models for low-power, real-time edge AI applications. To address the high computational cost of conventional CNN-based detectors such as YOLO, the group enhanced a Sigma–Delta spiking YOLOv3 framework by incorporating advanced training and optimization techniques. The proposed methods improved convergence, detection accuracy, and energy efficiency, and were validated using multiple real-world datasets. In addition, the trained model was successfully deployed on Intel’s Loihi 2 neuromorphic platform, demonstrating its feasibility for real-time and low-power operation. Through this project, undergraduate students gained hands-on experience in advanced AI research, from algorithm development to deployment on a neuromorphic hardware platform. This work demonstrates the value of active undergraduate participation in research and the CS Department’s commitment to integrating education and cutting-edge research.

  Two CS undergraduates, Juyoung Yun and Sol Choi, were the lead authors on a paper that won the Best Paper Award at the 2025 International Conference on Neural Information Processing (ICONIP), a long-running and well-regarded conference in the field of AI. The other authors were their supervisors: Profs. Francois Rameau, Prof. Byungkon Kang, and Prof. Zhoulai Fu. The paper is “Revisiting 16-bit Neural Network Training: A Practical Approach for Resource-Limited Learning”. Modern AI models are usually trained in 32-bit “full precision,” which is accurate but expensive in terms of memory and computation. Their work shows that one can safely train neural networks entirely in 16-bit precision, without the usual 32-bit “safety net,” even on modest hardware. A practical recipe, validated by theory and extensive experiments, is given for choosing the right settings so that training remains stable and the final model quality matches (and sometimes even rivals) 32-bit training. This is particularly important for settings where computing resources are limited, such as smaller labs, edge devices, or student projects that cannot rely on large GPU clusters. By cutting the precision in half while preserving performance, our approach makes state-of-the-art neural network training more accessible and more energy-efficient. This efficiency and practicality were key reasons the paper received the award.

Brain-inspired Computing Lab (BCL), led by Prof. Yoon Seok Yang, was selected to participate in the 2025 Preliminary Startup Package program organized by the Ministry of SMEs and Startups of Korea. BCL’s selected project, “Next-Generation AI Neuromorphic Processor Semiconductor Design”, is about developing a new type of on-device AI chip for edge computing that works more like the human brain. Most of today’s AI systems use GPUs, which are powerful but consume a lot of electricity and cost a great deal to run. As AI models get bigger and more complex, this problem is becoming even more serious. BCL aims to create a processor based on neuromorphic computing, which mimics the way neurons and synapses in the brain work. This makes it possible to run AI much faster and with far less energy, which is especially important for edge devices like self-driving cars, robots, and smart devices that need to work in real time.  In the project, BCL plans to design the chip itself, build a test version using an FPGA board, and make sure it can handle well-known datasets like ImageNet. BCL are also creating easy-to-use software tools so that developers can work with their chips just like they would with existing platforms such as TensorFlow or PyTorch. In the future, the goal is to make these chips available for many different applications and contribute to AI technology that is not only more powerful but also more energy-efficient and accessible.

Prof. Kang’s latest publications include a paper in the proceedings of the 2024 International Conference on Information and Knowledge Management (CIKM). This is a premier AI conference well-known for its papers on data mining, machine learning, and information management. It is recognized by many academic institutions, including NRF in Korea, as a class-A CS conference (CORE rank A).  The paper is about a machine learning algorithm that bypasses a shortcoming of AutoDiff, a core component in deep learning that enables us to train complex models. When training a model that uses linear algebraic routines, such as determinants, AutoDiff will give suboptimal performance. The paper proposes a reparameterization algorithm that yields the correct learning scheme as well as potentially saving more time by taking advantage of the parallelizability of the new formulation. A second paper, with Ph.D student Joonkyu Han as the main contributor, was published in the proceedings of the 29 th IEEE Pacific Rim International Symposium On Dependable Computing (PRDC). This is a well-regarded conference that showcases a variety of novel papers on software reliability, safety, security, and dependability. The paper deals with the use of visual and spatial information to authenticate a user during a login process. A fall-back authentication is an extra step of authentication taken when the user forgets his/her password. Typically-used secure question or email verification approaches have their shortcomings in terms of memorability and security. This work provides a way to authenticate a user by exploiting visual navigation through a virtual map; that is, a successful navigation through a map constitutes a successful login. Humans are particularly well-suited to remembering visual navigation, a fact that motivates and justifies our approach. Prof. Kang was also recognized as an Outstanding Reviewer for the 35th British Machine Vision Conference (November 2024), a highly ranked conference on ahigh-ranking computer vision.

The Conference on Computer Vision and Pattern Recognition (CVPR) 2024, regarded as one of the most prestigious and highest-impact conferences, has recognized Prof. Rameau as an Outstanding Reviewer.  This recognition was given to the top 2% of reviewers for their high-quality reviews (as judged by their Area Chairs) among 9,872 reviewers.  This is the second time Prof. Rameau has received the Outstanding Reviewer Award from CVPR.
