I need algorithm that assign object to cluster already created. In my case objects are Patients or sick person and clusters are diseases, and based on multiple questions patient should be assigned to cluster; of course the questions and responses (yes or no) will be already prepared for every disease.
For example : you are coughing ? if yes => do you have a fever? if Yes then maybe => corona disease. and so on. edit : decision tree algorithm
Have a look at ID-3; this allows you to build a decision tree based on pre-classified data, and any new patient can be classified according to their responses.
