It becomes more of a challenge in the case of countries like India with a strong 1.3 billion population. But COVID testing is a time consuming and resource-intensive process. So, to identify COVID positive patients and isolating them is very essential to stop its further spread. We all know that the main problem with this disease is that it is very infectious. Here we can take an example of recent COVID-19 epidemic problem related to the testing of positive cases. In this way, a recursive process of continues unless and until all the elements are grouped into particular categories and final nodes are all leaf nodes. The nodes from the root node are called either a leaf node or decision node depending on which one takes part in further decision making. The first and topmost condition which initiates the decision-making process is called the root condition. If we arrange the conditions and the decisions depending on those conditions and again one of those decisions resulting in further decisions the whole structure of decision making resembles a tree structure. Performing regression using decision treeĭecision tree problems generally consist of some existing conditions which determine its categorical response.Performing classification using decision tree.Application of Decision tree with Python.Classification and Regression Tree (CART).Read here my review of using Grammarly for more than two years. It is the best grammar and spellchecker available online. NB: Being a non-native English speaker, I always take extra care to proofread my articles with Grammarly. So, no doubt a decision tree gives a lot of liberty to its users. The decision tree can also handle both numerical and categorical data. There can be cases where the target variable has more than two categories, the decision tree can be applied in such multinomial cases too. The above two cases are where the target variable is a bivariate one i.e. Machine learning with python: a detailed discussion.In this article, we will learn how can we implement decision tree classification using Scikit-learn package of Pythonĭecision tree classification helps to take vital decisions in banking and finance sectors like whether a credit/loan should be given to a customer or not depending on his risk bearing credentials in medical test conditions like if a new medicine should be tried on a patient depending on his/her medical history and many more fields. Decision tree classification is a popular supervised machine learning algorithm and frequently used to classify categorical data as well as regressing continuous data.
