Text-to-image generation for soccer tactics

• Leveraged the Segment Anything Model (SAM) to extract and reposition players from real-world soccer images, enhancing dataset diversity for model training.
• Applied text-to-image diffusion models to generate structured tactical diagrams from textual descriptions, ensuring compliance with spatial constraints such as player formations, offside rules.

YUAttend Attendance App

• Developed an Android app using Java in Android Studio to track student attendance via GPS, displaying real-time location and attendance status for teachers.
• Integrated Firebase for cloud data storage, allowing teachers to manage courses and export attendance records to Excel.
• Planned for school-wide implementation, enabling all students to take attendance using the app.

Income Prediction Machine Learning Project

• Build a Machine Learning web application from scratch in Python with Streamlit. Use real world data from the stack overflow developer survey to build a machine learning model.
