I have data in table format having total 3 columns. One column for label, other two columns are features. So, such 30 rows(1 row contains 2 feature and 1 label) make one set of data with all 30 rows having same. In these 30 rows there could be some patterns of features. There could be more such sets of 30 rows(for 30 rows label will be same). So there will be 6 to 7 labels or class. I want algorithm to predict one label from 30 rows(one set). Which algorithm should I choose and how should I pre-process data?
