Jihye Park

Software Engineer, Samsung Electronics

September 2023 – Present

Working on designing and implementing LLM-based data analysis systems that can support engineers' decisions.

• Designed and implemented end-to-end LLM-based data analysis systems leveraging RAG and agentic AI frameworks, translating user requirements into system architecture, development, and evaluation strategies.
• Built and operated scalable data pipelines using Airflow on Kubernetes and Docker, enabling reliable processing of large-scale industrial data.

Worked on developing robust and explainable algorithms that can support engineers' decisions with visualized, quantitative, and objective evidence.

• Collaborated with domain experts to translate real-world manufacturing problems into deployable AI solutions.
• Designed and implemented algorithms to identify potential root-cause sensors from large-scale manufacturing data.
• Implemented sLLM applications by defining domain-specific labeling strategies and developing a BERT-based sensor classification model.

  Another promising area for future research is digital marketing. Digital marketing broadly refers to the process of using digital technologies such as social media to promote brands, acquire customers, and increase sales (Kannan et al., 2017). In the digital environment, customers can post reviews on products, services, brands, and companies on websites or social media platforms; and these reviews reach a much wider audience (Kannan et al., 2017). Customers can share word-of-mouth, which refers to informal communications between private parties concerning evaluations of goods and services (Anderson, 1998; Fornell, 1992; Singh, 1988; Westbrook, 1987), with thousands of users around the world as well as a few close friends. Thus, marketers are interested in promoting positive word-of-mouth and preventing negative word-of-mouth that could damage the brand's image (Gildin, 2022).
