I have extracted data from 4 satellites and ground data (for the past 10 years) of rainfall in excel files separately . Now i need to compare each satellite data with the ground data and find the difference and similarity between them. For example: if in satellite data the column "dog" has 100 values then i need to compare that column to the "dog" column in ground data using RNN. I need to compare each satellite data to the ground data one by one and find the similarity percentage and the difference percentage. If you guyz point me to some helpful resources or help me to get started, it will be much appreciated. I am kinda new to machine learning and this is for my masters research. Thank you.
