Transformative Learning at NTU: Team Untitled's Journey in the HOYA Chatbot Hackathon 2025

NTU's recent HOYA Chatbot Hackathon 2025 has become a vivid testament to the transformative power of hands-on learning and innovative problem-solving. NTU students, with their keen insights and relentless determination to bridge theory and practical application, have set a benchmark in the realm of enterprise chatbots. At the heart of this story is Team Untitled—a dynamic group of second-year students from NTU’s Disciplines of Data Science & Artificial Intelligence (DSAI) and Computer Science (CSC)—who turned an ambitious challenge into a launchpad for both technical innovation and professional growth.

The Hackathon Challenge: Bridging Academia with Industry​

Organised by the NTU Career & Attachment Office (CAO) in collaboration with HOYA Electronics, the hackathon called upon student teams to develop an enterprise-ready HR chatbot. The task was far from trivial. It demanded a solution that could streamline internal communications and optimize workflow processes in real-world corporate settings. With stakeholders expecting practical enhancements to existing systems, the project pushed the teams to not only innovate but also embed a high degree of usability and operational efficiency into their designs.
Key aspects of the challenge included:

• Enterprise Adaptability: Building a chatbot that could navigate complex HR queries, adapting to various internal communication needs.
• Integration of Advanced Technologies: Incorporating advanced solutions like natural language processing, prompt engineering, and retrieval-augmented generation (RAG).
• User-Centric Design: Focusing on the end-user experience by refining stakeholder engagement and agile development processes.

Team Untitled: A Journey from Classroom Concepts to Real-World Impact​

Team Untitled, composed of Cheng Yi Hsuen, Wang Shi Ying, Risha Sunil Shetty, and Singh Janhavee, exemplified how a well-coordinated group of enthusiastic learners can overcome the steep transition from theory to impact. Despite being in their second year, none had prior hands-on experience with chatbots. However, their determination to learn on the fly and adapt quickly allowed them to transform fundamental workshop concepts into a sophisticated, enterprise-grade solution.

Overcoming Initial Hurdles​

As the students dived into the hackathon challenge, they quickly realised the steep learning curve ahead:

• Rapid Learning Process: The team had to assimilate new information at an accelerated pace—embracing failure as an essential part of the learning journey.
• Cooperative Problem Solving: By leveraging their collective strengths, they managed to support one another, ensuring that each team member could contribute effectively.
• Adaptation from Theory to Practice: The transition involved integrating classroom theories with practical, applied AI skills, highlighting the importance of experiential learning in today’s rapidly evolving tech landscape.

The Role of Training and Mentorship in their Success​

A cornerstone of Team Untitled’s success was the Applied LLM & Microsoft Azure Workshop Series. Organised by CDEFG and the Innovation Lab at NTU's CCDS, the workshop series played a pivotal role by providing the students with targeted training in advanced AI and cloud services. Under the guidance of Professor Ong Chin Ann, the sessions tackled several crucial topics:

• Prompt Engineering: Techniques to translate user intents accurately into machine-understandable language.
• Retrieval-Augmented Generation (RAG): Methods to dynamically retrieve and generate contextually relevant responses.
• Vector Stores and Information Retrieval: Concepts that underpin modern search and embedding systems, essential for scaling chatbot performance.

These sessions not only demystified complex AI paradigms but also provided practical examples of integrating these principles with industry-standard tools. The team’s ability to leverage Microsoft Azure’s robust environment, in particular, demonstrated how cloud-based solutions can empower rapid prototyping and deployment—a skill highly relevant in today’s digital-first workplace.

Integrating External Tools​

To escalate their chatbot’s capabilities, Team Untitled explored the integration of external tools:

• Neo4j Graph: Leveraging graph databases enabled them to create nuanced data relationships, enhancing the chatbot's ability to understand and navigate intricate HR workflows.
• Computer Vision Modules: These were integrated to add layers of contextual awareness, particularly useful in scenarios requiring image-based information retrieval.

The willingness to integrate such diverse tools exemplifies a forward-thinking approach, where the boundaries of conventional chatbot development are expanded by harnessing multidisciplinary innovations.

Industry Impact and Stakeholder Engagement​

The impressive execution by Team Untitled did not go unnoticed. Stakeholders from HOYA Electronics were particularly taken by the team’s approach and the robustness of their prototype. In fact, the prototype became the benchmark against which other submissions were measured—a clear endorsement of the team’s innovative and practical design.

Learning Beyond Technical Skills​

The hackathon wasn’t merely a technical contest; it was a comprehensive learning experience that deepened the team’s understanding of stakeholder engagement and agile methodologies:

• User-Centric Focus: By prioritising feedback from mentors and industry experts, the team learned to iterate and refine their solution in real time.
• Agile Development: The process underscored the importance of iterative development and rapid prototyping, where feedback loops are crucial for refining functionality.
• Collaborative Dynamics: The project reinforced the value of team synergy, illustrating how diverse skill sets can converge to produce a solution that is both innovative and relevant.

The learning experience emphasized that real-world impact is achieved when technical prowess meets practical usability—a lesson that goes beyond the confines of academic classrooms.
