KAIST-KakaoBank Speeds Up 'Explainable AI' by 11 Times: "Boosts Financial AI Reliability
< (From left) Professor Jaesik Choi of the Kim Jaechul Graduate School of AI, Ph.D candidate Chanwoo Lee, Ph.D candidate Youngjin Park >
The research team led by Professor Jaesik Choi of KAIST's Kim Jaechul Graduate School of AI, in collaboration with KakaoBank Corp, announced that they have developed an accelerated explanation technology that can explain the basis of an Artificial Intelligence (AI) model's judgment in real-time. This research achievement significantly increases the practical applicability of Explainable Artificial Intelligence (hereinafter XAI) technology in fields requiring real-time decision-making, such as financial services, by achieving an average processing speed 8.5 times faster, and up to 11 times faster, than existing explanation algorithms for AI model predictions.
In the financial sector, a clear explanation for decisions made by AI systems is essential. Especially in services directly related to customer rights, such as loan screening and anomaly detection, regulatory demands to transparently present the basis for the AI model's judgment are increasingly stringent. However, conventional Explainable Artificial Intelligence (XAI) technologies required the repeated calculation of hundreds to thousands of baselines to generate accurate explanations, resulting in massive computational costs. This was a major factor limiting the application of XAI technology in real-time service environments.
To address this issue, Professor Choi's research team developed the 'ABSQR (Amortized Baseline Selection via Rank-Revealing QR)' framework for accelerating explanation algorithms. ABSQR noticed that the value function matrix generated during the AI model explanation process has a low-rank structure. It introduced a method to select only a critical few baselines from the hundreds available. This drastically reduced the computation complexity, which was previously proportional to the number of baselines, to be proportional only to the number of selected critical baselines, thereby maximizing computational efficiency while maintaining explanatory accuracy.
Specifically, ABSQR operates in two stages. The first stage systematically selects important baselines using Singular Value Decomposition (SVD) and Rank-Revealing QR decomposition techniques. Unlike existing random sampling methods, this is a deterministic selection method aimed at preserving information recovery, which guarantees the accuracy of the explanation while significantly reducing computation. The second stage introduces an amortized inference mechanism, which reuses the pre-calculated weights of the baselines through cluster-based search, allowing the system to provide an explanation for the model's prediction result in real-time service environments without repeatedly evaluating the model. The research team verified the superiority of ABSQR through experiments on various real-world datasets. Tests on standard datasets across five sectors—finance, marketing, and demographics—showed that ABSQR achieved an average processing speed 8.5 times faster than existing explanation algorithms that use all baselines, with a maximum speed improvement of over 11 times. Furthermore, the degradation of explanatory accuracy due to speed acceleration was minimized, maintaining up to 93.5% of the explanation accuracy compared to the baseline algorithm. This level is sufficient to meet the explanation quality required in real-world applications.
< ABSQR Framework Overview. (1) The baseline selection stage utilizes the low-rank structure of the value function matrix to select only a small number of key baselines, and (2) the accelerated search stage reuses the pre-calculated baseline weight coefficients based on clusters. This dramatically reduces the computation complexity, which was proportional to the number of baselines, to be proportional only to the number of selected key baselines. >
A KakaoBank official stated, "We will continue relentless research and development to enhance the reliability and convenience of financial services and introduce innovative financial technologies that customers can experience." Chanwoo Lee and Youngjin Park, co-first authors from KAIST, explained the significance of the research: "This methodology solves the crucial acceleration problem for real-time application in the financial sector, proving that it is possible to provide users with the reasons behind a learning model's decision in real-time." They added, "This research provides new insights into what constitutes unnecessary computation and the selection of important baselines in explanation algorithms, practically contributing to the improvement of explanation technology efficiency." This research, co-authored by PhD candidates Chanwoo Lee and Youngjin Park from the KAIST Kim Jaechul Graduate School of AI, and researchers Hyeongeun Lee and Yeeun Yoo from the KakaoBank Financial Technology Research Institute, was presented on November 12 at the 'CIKM 2025 (ACM International Conference on Information and Knowledge Management)', the world's highest-authority academic conference in the field of information and knowledge management. ※ Paper Title: Amortized Baseline Selection via Rank-Revealing QR for Efficient Model Explanation

Development of Core NPU Technology to Improve ChatGPT Inference Performance by Over 60%
Latest generative AI models such as OpenAI's ChatGPT-4 and Google's Gemini 2.5 require not only high memory bandwidth but also large memory capacity. This is why generative AI cloud operating companies like Microsoft and Google purchase hundreds of thousands of NVIDIA GPUs. As a solution to address the core challenges of building such high-performance AI infrastructure, Korean researchers have succeeded in developing an NPU (Neural Processing Unit)* core technology that improves the inference performance of generative AI models by an average of over 60% while consuming approximately 44% less power compared to the latest GPUs.
*NPU (Neural Processing Unit): An AI-specific semiconductor chip designed to rapidly process artificial neural networks.
On the 4th, Professor Jongse Park's research team from KAIST School of Computing, in collaboration with HyperAccel Inc. (a startup founded by Professor Joo-Young Kim from the School of Electrical Engineering), announced that they have developed a high-performance, low-power NPU (Neural Processing Unit) core technology specialized for generative AI clouds like ChatGPT.
The technology proposed by the research team has been accepted by the '2025 International Symposium on Computer Architecture (ISCA 2025)', a top-tier international conference in the field of computer architecture.
The key objective of this research is to improve the performance of large-scale generative AI services by lightweighting the inference process, while minimizing accuracy loss and solving memory bottleneck issues. This research is highly recognized for its integrated design of AI semiconductors and AI system software, which are key components of AI infrastructure.
While existing GPU-based AI infrastructure requires multiple GPU devices to meet high bandwidth and capacity demands, this technology enables the configuration of the same level of AI infrastructure using fewer NPU devices through KV cache quantization*. KV cache accounts for most of the memory usage, thereby its quantization significantly reduces the cost of building generative AI clouds.
*KV Cache (Key-Value Cache) Quantization: Refers to reducing the data size in a type of temporary storage space used to improve performance when operating generative AI models (e.g., converting a 16-bit number to a 4-bit number reduces data size by 1/4).
The research team designed it to be integrated with memory interfaces without changing the operational logic of existing NPU architectures. This hardware architecture not only implements the proposed quantization algorithm but also adopts page-level memory management techniques* for efficient utilization of limited memory bandwidth and capacity, and introduces new encoding technique optimized for quantized KV cache.
*Page-level memory management technique: Virtualizes memory addresses, as the CPU does, to allow consistent access within the NPU.
Furthermore, when building an NPU-based AI cloud with superior cost and power efficiency compared to the latest GPUs, the high-performance, low-power nature of NPUs is expected to significantly reduce operating costs.
Professor Jongse Park stated, "This research, through joint work with HyperAccel Inc., found a solution in generative AI inference lightweighting algorithms and succeeded in developing a core NPU technology that can solve the 'memory problem.' Through this technology, we implemented an NPU with over 60% improved performance compared to the latest GPUs by combining quantization techniques that reduce memory requirements while maintaining inference accuracy, and hardware designs optimized for this".
He further emphasized, "This technology has demonstrated the possibility of implementing high-performance, low-power infrastructure specialized for generative AI, and is expected to play a key role not only in AI cloud data centers but also in the AI transformation (AX) environment represented by dynamic, executable AI such as 'Agentic AI'."
This research was presented by Ph.D. student Minsu Kim and Dr. Seongmin Hong from HyperAccel Inc. as co-first authors at the '2025 International Symposium on Computer Architecture (ISCA)' held in Tokyo, Japan, from June 21 to June 25. ISCA, a globally renowned academic conference, received 570 paper submissions this year, with only 127 papers accepted (an acceptance rate of 22.7%).

The “2025 KAIST Global Entrepreneurship Summer School (2025 KAIST GESS),” organized by the Office of Global Initiative of the KAIST International Office (Vice President So Young Kim), successfully concluded. Now in its fourth year, the program was designed to provide KAIST students with firsthand experience of the world’s leading startup ecosystem in Silicon Valley, USA, and to strengthen their practical capabilities to take on challenges on the global stage.
This year’s 2025 KAIST GESS welcomed approximately 40 participants, including 24 undergraduate and graduate students selected through document screening, interviews, team presentations, mentoring, and peer evaluations, as well as 16 Impact MBA students from the College of Business. The selected undergraduate and graduate participants underwent two months of pre-program training and received mentoring from experienced entrepreneurs to refine their business models and elevate their project ideas. Meanwhile, Impact MBA students joined the Silicon Valley program onsite, attending key lectures and networking sessions to broaden their understanding of the global startup ecosystem.
From June 22nd, participants spent seven days in Silicon Valley completing the global entrepreneurship curriculum. The program was operated in cooperation with major organizations including the KOTRA Silicon Valley IT Center, Korea-US AI Semiconductor Innovation Center (K-ASIC), and Plug and Play Tech Center. Local experts delivered lectures on topics such as “Startup Culture,” “Learning from Failures” and “Networks and Capital.”
Participants also had the opportunity to visit startups led by KAIST alumni and local entrepreneurs, gaining valuable insights from firsthand stories about global entrepreneurship. Companies visited included Medic Life Sciences (CEO Kyuho Han) and ImpriMed (CEO Sungwon Lim). Through these visits, participants received practical advice on market entry strategies and overcoming challenges in the global arena.
As part of their first onsite schedule, KAIST students attended an interactive fireside chat titled “Global Entrepreneurship and AI,” where they engaged in in-depth discussions on the future of AI-driven global startups. The session featured three distinguished speakers: Jay Kim, Head of US Business Development at Hyper Accel; Chandra Shekhar Dhir, AI/ML Director at JPMorgan Chase’s Machine Learning Center of Excellence; and Taesu Kim, co-founder of AI voice synthesis startup Neosapience and KAIST alumnus. Taesu Kim shared, “Facing serious health issues made me reflect on my life, and after recovering, I wanted to pursue something that could create a real impact on society, which led me to start my own company.” He also advised students to “take time at important turning points in life to deeply think about what you truly want to do and how you can contribute to society.
In line with the core value of ‘paying it forward’—a fundamental principle of global entrepreneurship learned in Silicon Valley—GESS participants engaged in a community service project titled “Let’s Play with AI+Tech,” organized in collaboration with the Sunnyvale community and Foothill College. Leveraging their strong foundation in AI, KAIST students designed and led a hands-on ‘Doodle AI’ educational program to make foundational AI concepts accessible and engaging for underrepresented local elementary school children and their parents, fostering meaningful community interaction.
On the final day of the 2025 KAIST GESS, a pitch competition was held with participation from Silicon Valley venture capitalists and accelerators. Participants presented their business models, developed over the two-month program, to a panel of judges. The winning team was eaureco, and Si Li Sara Aow (Civil and Environmental Engineering) shared, “GESS was a valuable opportunity to test and hone practical entrepreneurship skills beyond mere networking.” She added, “At first, I lacked confidence, but challenging myself to pitch in the final presentation gave me the courage to take one step closer to global entrepreneurship. Pitching in Silicon Valley, the heart of global startups, was an invaluable experience that will shape my path as a global entrepreneur.”
The program concluded with a special lecture by Jay Eum, a seasoned Silicon Valley venture capitalist and a judging panel member for GESS over the past three years. He shared key insights on startup success from an investor’s perspective, advising, “The journey of entrepreneurship is never easy, but the sooner you start, the better.” He further encouraged participants to “focus on solving problems in local markets, but do not fear challenging global markets,” inspiring them with courage and actionable advice.
So Young Kim, Director of the KAIST Office of Global Initiative, said, “We hope the 2025 KAIST GESS serves as a stepping stone for KAIST students to grow into influential entrepreneurs on the global stage,” adding, “This program is also expected to further enhance KAIST’s international reputation.”
Byungchae Jin, Faculty Chair of the KAIST Impact MBA, College of Business, highlighted the program's educational benefits, stating, “Engaging directly with local entrepreneurs and gaining practical experience in Silicon Valley's startup environment provide students with hands-on learning and significant inspiration.”
The 2025 KAIST GESS was jointly hosted by the KAIST Office of Global Initiative, Impact MBA, and Startup KAIST. Moving forward, KAIST plans to continue expanding its field-based global entrepreneurship education by linking with key global hubs like Silicon Valley, fostering next-generation global leaders who will lead innovation and challenge the status quo.

PhD Graduate Mekuria Teklemariam Inspired to Better Serve Ethiopia
Ethiopia’s Former Minister of Urban Development and Housing Mekuria Teklemariam became a KAIST alumnus, earning his PhD in the Global IT Technology Program (ITTP) last month. Dr. Telkemariam completed his degree summa cum laude in business administration in four years. He is the highest-ranking official among the ITTP Program recipients.
Dr. Teklemarian cited the ‘Saemaul Undong,’ also known as the New Community Movement as well as the strong infrastructure of IT industry as part of the driving forces behind Korea’s rapid economic success and this inspired him to choose KAIST as his academic destination.
The Global ITTP was launched in 2006 to educate elite public officials from diverse countries on information and communication technology. This program has played a vital role in transferring Korea’s advanced information and communications technology to many countries whose industries are in the budding stages.
Approximately 200 officials from over 50 countries have enrolled in the ITTP program, and the program has expanded to cover diverse areas of ICT and grown into a global network of ICT leaders abroad. The 2020 Class graduated five PhDs and five master’s degree holders.
Dr. Teklemariam plans to benchmark Korea to aid the development of Ethiopia when he returns home. “Korea is a country that has made remarkable progress in all areas including politics and economics in the last few decades, emerged from one of the poorest countries in the 1960s to be among the largest economies in the world today,” Dr. Telkemariam said.
“So I wanted to study what transformed Korea to make such a miraculous transformation academically for my country’s own development too,” he added, explaining his motivation to study in Korea. He also cited diverse IT education programs for the elderly as a Korean policy he would like to see applied in his country.
The 50-year-old former minister and incumbent urban affairs advisor to the prime minister of Ethiopia was elected to the country's parliament a decade ago, becoming the youngest member in Ethiopian history. He has led the economic development of Ethiopia in the areas of smart city development, land management, and housing development policies.
While studying at KAIST, Dr. Telkemariam became the two-time winner of the Outstanding Collaborative Research Award presented by the KAIST Institute for IT Convergence through collaborative research with the National IT Industry Promotion Agency (NIPA) and the Science and Technology Policy Institute (STEPI).
In addition, his graduation thesis, "Differentiating mobile broadband policies across diffusion stages: A panel data analysis" was published in Telecommunications Policy.
President Sung-Chul Shin met with him during a luncheon meeting before he returned to home. During the meeting Dr. Telkemariam said, “I was impressed by the Korean people, who not only work hard to do their part wherever they are, but also put whatever they say into practice. I will apply and practice what I have learned from Korea and KAIST to Ethiopia.” President Shin responded, “We shall seek to find ways to cooperate that can be practically used to expand exchanges between the two countries.”

Biomarker Predicts Who Will Have Severe COVID-19
- Airway cell analyses showing an activated immune axis could pinpoint the COVID-19 patients who will most benefit from targeted therapies.-
KAIST researchers have identified key markers that could help pinpoint patients who are bound to get a severe reaction to COVID-19 infection. This would help doctors provide the right treatments at the right time, potentially saving lives. The findings were published in the journal Frontiers in Immunology on August 28.
People’s immune systems react differently to infection with SARS-CoV-2, the virus that causes COVID-19, ranging from mild to severe, life-threatening responses.
To understand the differences in responses, Professor Heung Kyu Lee and PhD candidate Jang Hyun Park from the Graduate School of Medical Science and Engineering at KAIST analysed ribonucleic acid (RNA) sequencing data extracted from individual airway cells of healthy controls and of mildly and severely ill patients with COVID-19. The data was available in a public database previously published by a group of Chinese researchers.
“Our analyses identified an association between immune cells called neutrophils and special cell receptors that bind to the steroid hormone glucocorticoid,” Professor Lee explained. “This finding could be used as a biomarker for predicting disease severity in patients and thus selecting a targeted therapy that can help treat them at an appropriate time,” he added.
Severe illness in COVID-19 is associated with an exaggerated immune response that leads to excessive airway-damaging inflammation. This condition, known as acute respiratory distress syndrome (ARDS), accounts for 70% of deaths in fatal COVID-19 infections.
Scientists already know that this excessive inflammation involves heightened neutrophil recruitment to the airways, but the detailed mechanisms of this reaction are still unclear.
Lee and Park’s analyses found that a group of immune cells called myeloid cells produced excess amounts of neutrophil-recruiting chemicals in severely ill patients, including a cytokine called tumour necrosis factor (TNF) and a chemokine called CXCL8.
Further RNA analyses of neutrophils in severely ill patients showed they were less able to recruit very important T cells needed for attacking the virus. At the same time, the neutrophils produced too many extracellular molecules that normally trap pathogens, but damage airway cells when produced in excess.
The researchers additionally found that the airway cells in severely ill patients were not expressing enough glucocorticoid receptors. This was correlated with increased CXCL8 expression and neutrophil recruitment.
Glucocorticoids, like the well-known drug dexamethasone, are anti-inflammatory agents that could play a role in treating COVID-19. However, using them in early or mild forms of the infection could suppress the necessary immune reactions to combat the virus. But if airway damage has already happened in more severe cases, glucocorticoid treatment would be ineffective.
Knowing who to give this treatment to and when is really important. COVID-19 patients showing reduced glucocorticoid receptor expression, increased CXCL8 expression, and excess neutrophil recruitment to the airways could benefit from treatment with glucocorticoids to prevent airway damage. Further research is needed, however, to confirm the relationship between glucocorticoids and neutrophil inflammation at the protein level.
“Our study could serve as a springboard towards more accurate and reliable COVID-19 treatments,” Professor Lee said.
This work was supported by the National Research Foundation of Korea, and Mobile Clinic Module Project funded by KAIST.

KAIST Technology Value Tops in Commercialization Market
KAIST became the first Korean university to achieve 10.183 billion KRW in annual technology royalties, and was also selected as an ‘Institution of Outstanding Patent Quality Management’ and an ‘Institution of Outstanding Public Patent Technology Transfer’ for 2020.
KAIST earns its technology royalties through 56 technology transfer contracts. Following KAIST in the rankings were Seoul National University (SNU) in second place with 8.8 billion KRW from 87 contracts and Korea University (KU) in the third with 5.4 billion KRW from 133 contracts. The data shows the high value of KAIST-created technology in the market.
The Korean Intellectual Property Office (KIPO) started to recognize the Institution of Outstanding Patent Quality Management this year to encourage profit-driven patent management at universities and public research institutes, and KAIST was selected as one of the four first recipients of this distinction.
In addition, KAIST was selected as an Institution of Outstanding Public Patent Technology Transfer, a title given by KIPO to three universities and public research institutes this year with outstanding achievements in technology transfers and commercialization to encourage patent utilization.
Director of the KAIST Institute of Technology Value Creation (ITVC) Professor Kyung-cheol Choi said that KAIST’s achievement in annual technology royalties and technology transfers and commercialization were prime examples of accelerating competitiveness in intellectual property through innovative R&D investment.
In April, KAIST expanded and reorganized its Industry-Academia Collaboration Team into the ITVC to support technology transfers and commercialization. Specialized organizations such as the Intellectual Property and Technology Transfer Center and Industrial Liaison Center have been established under the ITVC, and industry experts have been recruited as special professors focusing on industry-academia collaborations to enhance its specialized functions.
KAIST also operates an enterprise membership system and technology consulting system, aimed at sharing its outstanding intellectual property within domestic industries. In 2019, it secured a technology transfer commercialization fund of 1.2 billion KRW available for three years under KIPO’s Intellectual Property Profit Reinvestment Support Program (formerly the Korean Patent Gap Fund Creation Project).
This program was introduced to bridge the gap between the technology developed in universities and the level of technology required by industry. Under the program, bold investments are made in early-stage technologies at the research paper or experiment phase.
The program encourages enterprises to take active steps for the transfer of technologies by demonstrating their commercial potential through prototype production, testing and certification, and standard patent filing. KAIST is currently funding approximately 20 new technologies under this program as of July 2020.
KAIST’s outstanding intellectual property management has also received international recognition, with its selection as Asia’s leading institution in university R&D intellectual property at the Intellectual Property Business Congress (IPBC) Asia 2019 held in Tokyo, Japan last October.
