I am new to this data science domain. I have recently completed statistics course from Udacity and have gone through various courses/ article for pre model stage like data exploration, feature engineering to understand the data in detail. Now for next step, I want to explore machine learning algorithms and there are enough methods available( [list is exhaustive]). I am not able to structure these algorithms as level1, level2, level3 …
Please help me to structure these algorithm as level1, level2, level3…so that a beginner can start with level1 and by the end of level 3/4, he/ she is able to solve any data science challenge.
