Deep Learning with Finance

Hi, I am MTech student in computer science. I want to work on finance domain with machine learning. So can anyone suggest me some research topic. On which we can work for last year thesis. During my MTech my major focus on machine learning and deep learning around topic. But I have an interest in the finance domain also I did some project like https://github.com/Zdong104/FNSPID_Financial_News_Dataset with market regime prediction. But now I am finding an solid research topic for the my final year. Is there any suggestion for this ?
