In this preliminary round of the Datathon2024 competition, the task we needed to tackle was a fraud detection challenge. Throughout the process, I personally learned so much, and thankfully we finished with quite a satisfactory result.
We implemented various advanced techniques in feature extraction, data cleaning, feature selection, and all the way to tuning.
This was definitely one of the most interesting problems I have faced, and the complete notebook can be found here. Should you have interest in this topic or would like to inquire about it, feel free to contact me!
