I am a master student in applied statistic, I am planing to do my master on machine learning and its applications in statistics, can any one suggest a new topic in this field?
My suggestion is, "Point of Significance: Statistics vs Geo-Statistics".
Under this topic you can use the concept of descriptive statistics and also use machine learning approach to prove the Geo-Statistics evolves nowadays in a faster space.
I have attached a book link. Hopefully this book fulfill your requirements.
Actually, Geo-Statistics is dealt with such kind of statistics used to analyze and predict the values associated with spatial or spatiotemporal phenomena using GIS, Machine learning approach etc. that may be related to Geography or Geology. I think now your queries may fulfill.
