ML Expert - Data analysis and classification

The task involves analysing about 50 sheets of prediction results from ML models. The task is to analyse the data sets independently or together with the training data sets and then determine which model will give the best prediction results based on the prediction history available in the 50 data sets. The analysis should be done only on the data with or without training data sets and not the ML model. The analysis is concerning the
results of the 50 data sets available. After the analysis, I will be able to tell which model is best suited for the 51st data set.
