Now let’s create the classification decision tree using the DecisionTreeClassifier function from the sklearn.tree library. Although the DecisionTreeClassifier function has many parameters that I invite you to
Learn the basics of Decision Trees - a popular and powerful machine learning algorithm and implement them using Python
If we use just the basic implementation of a Decision Tree, it will probably not fit very well.Therefore, we need to tweak the parameters in order to get a good fit. This is very easy and won't require much effort. 如果你只是执行基本的决策树,它拟合的可能并不好,因此,我们需要调整参数来...
Now, let’s do the actual decision tree implementation. I’m making it scikit-learn compatible, hence I use some classes fromsklearn.base. If you are not familiar with that, check out my article abouthow to build scikit-learn compatible models. Let’s implement! import numpy as np from ...
The programming language is Python 3.8. The deep learning framework is TensorFlow 2.9.1. The data processing libraries are Pandas 1.4.3 and NumPy 1.22.0. The visualization tools are Matplotlib 3.5.1 and Seaborn 0.11.2. The parameter setting in this paper is optimized for ID3 decision tree ...
We also discussed its pros, cons, and how to optimize decision tree performance using parameter tuning. Hopefully, you can now utilize the decision tree algorithm to analyze your own datasets. If you want to learn more about Machine Learning in Python, take DataCamp's Machine Learning with ...
In this article, we have learned how to model the decision tree algorithm in Python using the Python machine learning library scikit-learn. In the process, we learned how to split the data into train and test dataset. To model decision tree classifier we used the information gain, and gini...
