AI and Robotics
International Robotics Olympiad (IRO)
IRO was a special experience for me, not because it validated my robotics skills, but because of the process itself. At IRO, my main task was to design, code, and operate a robot to complete the given mission—a straightforward evaluation of technical ability. However, it was my first time in Greece, my first time meeting friends from different countries, and the first time I felt the pure joy of sharing a passion for robotics with others. These experiences were what ultimately made me decide to continue studying robotics.
DECFON (CS club)
When I walked into the club room each morning and switched on the lights, the room was filled with four rows of desks, each brimming with computers. As a freshman, I sat in the front row, eager to prove myself, seeking recognition and validation from the seniors. By sophomore year, I moved to the second row, where I started selecting and mentoring new members. As a senior, I sat in the back, overseeing everything, offering guidance, and shaping the direction of the group. Just as my perspective changed depending on which row I sat in, so did my understanding of computer science. What once was the subject of fascination became a field of study, and now, a tool to achieve my dreams.
I still find myself itching to give advice to the freshmen, offering insights they may not yet fully understand. But I’ve realized that each of us has our own DEFCON, and the meaning it holds is different for everyone. My role now is to pass down this community that shaped me, ensuring future members can grow and find their own meaning in it. That's all is needed.
The significance of a community lies in its ability to foster growth, unity, and connection among its members through collaboration, competition, and interaction. For me, DEFCON was not just a community but a place that cultivated both my passion and skills in computer science for the past three years.
Research - Enhanced Adversarial Attack on Voice Conversion using
Layer-wise Relevance Propagation
What use is technology if it can't be used for the good? AI is outpacing our ability to regulate and adapt. They are frequently used in crimes such as AI voice phishing-and I wanted to solve that.
Voice conversion technology is used in voice phishing scams by imitating voices of the victim's acquaintances. An adversarial attack prevents voice conversion by slightly altering the voice, making it sound the same to humans but disrupting the conversion systems. My research applied an explainable AI method to identify the important parts of the voice for a speech recognition task, and only altered those parts during an adversarial attack. As a result, I made the changes in the voice less noticeable(up to 14%), while maintaining attack performance.
This summer break, which I dedicated to this research, is just the beginning. I will continue to pursue research to ensure that technology is used solely for good in the future.
