From September 25 to 27, 2025, a selected group of former students and their mentors from the Codespring Mentoring Program had the honor of taking part in SISY 2025 — the IEEE 23rd International Symposium on Intelligent Systems and Informatics in Subotica, Serbia. Participating in this event marked the culmination of over a year’s dedicated work of these young professionals: the students, guided by our dedicated software developers, presented in front of an international professional audience the projects that they had been working on since summer 2024.

This way, the three-day event was not only a technical milestone but also a memorable team-building experience for all the participants. Between inspiring keynotes, presentations, and informal gatherings, our MP coordinators, mentors and students strengthened their bonds, shared their knowledge, and celebrated their achievements.

Conference Attendance and Side Activities at SISY 2025

The team arrived in Subotica on Thursday and checked in at the accommodation in Palić, a charming resort area renowned for its art nouveau villas and lakeside promenades. This picturesque area set the perfect tone for both the academic and social sides of the conference.

Before the official opening, we had the possibility to hold a final rehearsal of the student presentations. Each student received last-minute feedback, tips, and encouragement from peers and mentors, ensuring that everyone felt prepared for the stage.

After that, we attended the conference opening ceremony and the first plenary sessions. The atmosphere was inspiring, as the symposium returned to its “home ground” in Subotica after two years in Pula, Croatia. For many of our mentors, it was a warm reunion with colleagues and old friends from past editions—Codespring teams have been attending SISY since 2013, and this continuity adds special value to each appearance.

The evening ended with a city tour and a team dinner in downtown Subotica, allowing participants to discover the city’s architectural gems while bonding over local cuisine.

High-level Project Presentations

Friday was the most anticipated day for our students. The presentations took place at Subotica Tech (VTS), in two sessions: Informatics and Intelligent Robotics.

Our young authors impressed the audience with their presentations about four innovative projects:

Session on Informatics

• B.o.B.: Intelligent Chatbot Employing Document-Centric Data Processing

Authors: K. Ákos, H. Gábor | Mentors: F. Eszter, P. Kinga | Coordinator: B. Nándor

B.o.B. is a web-based chatbot powered by AI and RAG (Retrieval-Augmented Generation) technology, designed to answer questions based strictly on user-provided documents. Users can upload files, start conversations, and receive context-specific answers. Features include session management, user accounts, answer rating, and intuitive browsing of conversations and files. The project showcased how natural language processing can enhance user interaction with personal or institutional document repositories.

• Precise Indoor Positioning Using Ultra-Wideband (UWB)

Authors: M. Walter, F. Szilárd |Mentors: Sz. Dávid, F. Lóránt | Coordinator: S. Csaba

This project explored the use of UWB technology for high-accuracy, real-time indoor positioning—outperforming Bluetooth Low Energy (BLE) and capable of working in shielded environments. Tests were conducted with Qorvo’s DWM1001-DEV and DWM3001-CDK devices. The solution is suitable for navigation in parking garages, automated door systems in office buildings, point-of-interest marking, and group member localization.

• VoteHub: Highly Customizable and Secured Voting System for Institutions with AI-Based Transcript Generation

Authors: B. Norbert, K. Gergő |Mentors: R.-N. Kata, K.-F. Bálint | Coordinator: S. Károly

VoteHub is a secure, institution-level voting and meeting management system. It supports both online and hybrid assemblies, offering customizable voting rights per agenda point, automated membership assignment, and integrated statistics and transcripts. Its architecture includes a central server, a web-based management interface, and a mobile app for participants, creating a comprehensive solution for organizational governance.

Session on Intelligent Robotics

• Automated Testing of Interaction-Requiring Devices with a Robotic Arm and Object Detection

Authors: D. Levente, D. Beniamin |Mentors: Sz. Arnold, M. Dénes, K. Gyöngyi | Coordinator S. Csaba

This project combined robotics, AI-driven computer vision, and automated software testing. A Dobot Magician Lite robotic arm was used to physically interact with devices such as controllers and touchscreens, while a camera and deep learning models identified input components. Calibrated spatial mapping allowed the robot to execute repeatable tests, with a validation algorithm ensuring the accuracy of results. The project demonstrated how automation can reduce manual testing effort in hardware-software integrated systems.

Each presentation was well-received, with authors not only delivering clear explanations but also engaging in interactive discussions with the audience. Mentors noted the visible progress from rehearsals to the live sessions—the students’ confidence and professionalism shone through.

Social Activities with Tasty Experiences and Views

The day concluded with a delicious dinner and wine tasting in an award-winning winery. Sharing dinner by the lakeside created a relaxed atmosphere where students and mentors could mingle and reflect on the day’s achievements. A lighthearted celebration followed: after all the stress of presenting, the team could finally relax.

On Saturday, after the remaining conference sessions, the team began the journey home. While the official program has ended, the sense of accomplishment and the strengthened relationships among students and mentors would carry forward into future projects.

Reflections from the Mentors

According to Károly, one of the coordinators, the SISY 2025 conference was extremely well-organized, with a warm and familiar atmosphere. He added that returning to Subotica felt like coming home, and it was wonderful to reconnect with long-standing partners. Our former students’ presentations were of high quality and showcased the strong mentorship process. Staying in Palić added a special touch—it was not just about attending a conference but also about celebrating teamwork, growth, and shared achievements. Some students even rejoined us this year as fresh colleagues, which made the event even more meaningful, he summed up.

“Our students worked with great dedication, putting together papers that not only made it into SISY conference programme but they will also be published in recognized professional periodicals. That recognition required additional revisions, but the students gladly invested the effort, knowing how rare and prestigious such an opportunity is,” added Gyöngyi, one of the mentors from Codespring | Softech.

As she stated, on the opening day, they could sense the importance of the moment—the students carefully carried their formal shirts on hangers, knowing this was no ordinary trip. “Watching them perform on stage, we mentors were proud and impressed. Their talks were clear, engaging, and, in our view, the best of their sessions. The success was celebrated with local food, drinks, and the joy of knowing that their hard work had truly paid off.”

Key Takeaways from SISY 2025

• Professional Growth: Students gained hands-on experience presenting research at an international IEEE conference, receiving valuable feedback from experts.
• Team Spirit: The three days combined academic rigor with cultural exploration, strengthening bonds between students and mentors.
• Recognition: the papers will be published recognized professional periodicals, one of them being selected to be published in Acta Polytechnica Hungarica which is a significant academic achievement.
• Tradition and Continuity: Codespring has been part of SISY since 2013, and each year adds new milestones to this journey.

Closing Remarks

SISY 2025 in Subotica was more than a conference—it was the celebration of a year-long mentorship journey, a platform for innovation, and a memorable shared experience. Our 17 participants—students, mentors, and coordinators alike—returned with not only academic accomplishments but also lasting memories, stronger professional relationships, and fresh motivation for the challenges ahead.

As we look forward to the next edition of SISY, we are proud of what our team has achieved and grateful for the opportunity to contribute to the international community of intelligent systems and informatics.
