The technical potential of a preliminary research study is that you are subsequently able to determine what type of AI and machine learning your data is capable of supporting.
In essence, these concepts cover a wide range of techniques that are all intended to uncover trends in the data that you have, where the feasibility study clarifies which options on the list have the greatest potential given the data at hand. These include classification, regression, suggestion algorithms, Natural Language Processing, and image recognition.
What suits you best depends on the data you have available and what you would like to have anticipated.
