Kakao Bank has advanced its research in artificial intelligence and data science through its Financial Tech Lab, revealing new capabilities aimed at enhancing explainable AI and improving financial search in the Korean language. The announcement was made on Thursday, marking a significant contribution to the evolving landscape of financial technology.
The research addresses two critical challenges in financial AI: increasing model transparency and improving the accuracy of processing Korea-specific financial language and context. This initiative comes as the banking sector increasingly relies on AI for various applications, from compliance to customer service.
At the International Conference on Information and Knowledge Management held in Seoul in mid-November, Kakao Bank presented a high-efficiency technique for explainable AI developed in collaboration with the Korea Advanced Institute of Science and Technology. The importance of explainability in regulated sectors like finance cannot be overstated; however, many existing methods require significant computational resources that hinder real-time application. Kakao Bank claims its new approach enhances computation speed by up to 8.5 times while maintaining the quality of explanations. This advancement is expected to bolster compliance with South Korea’s new AI Basic Act and improve systems involved in fraud detection.
Later that month, at the International Conference on AI in Finance in Singapore, the lender showcased its research on Korean-language financial information retrieval. Given that many large language models are predominantly trained on English data, they tend to struggle with Korean financial terminology, leading to decreased accuracy in search results and overall system reliability. In response, Kakao Bank has developed a dedicated benchmark dataset designed to objectively assess AI performance on Korean-language financial queries. This resource has been recognized by the academic community as a foundational tool for future research in the field.
A bank official noted, “Kakao Bank’s recognition at global academic societies shows its technology is already competitive by international standards. We will continue advancing reliability and customer convenience through research that can be applied directly to everyday financial services.” This commitment underscores Kakao Bank’s strategy to not only innovate within its existing frameworks but also to set a standard for financial technology in South Korea and beyond.
The emphasis on explainable AI and the development of resources tailored to the Korean language reflect a growing awareness of the unique challenges faced by non-English speaking markets in the AI landscape. As AI continues to proliferate across various sectors, the need for models that are both accurate and understandable becomes increasingly important, particularly in regulated environments like finance.
Looking forward, Kakao Bank’s initiatives could significantly impact the broader financial technology landscape in South Korea. As the demand for reliable AI solutions grows, the bank’s research could inspire further innovations, setting the stage for enhanced customer experiences and increased regulatory compliance. The ongoing evolution of AI in finance not only stands to reshape the industry’s operational framework but also promises to elevate service standards for consumers navigating an increasingly complex financial world.
