How to classify “wine” using SKLEARN Boosting Ensemble models – Multiclass Classification in Python
In machine learning, one of the most common tasks is to classify data into different categories. For example, classifying different types of wine as red or white. In this blog post, we’ll take a look at how we can use a technique called “boosting” to classify wines using the python library scikit-learn (also known as sklearn).
Boosting is a method of ensemble learning, which means that it combines the predictions of multiple simpler models to make a more accurate final prediction. In the case of wine classification, we would train multiple “weak” models (such as decision trees) on the wine data and then combine their predictions to make a final “strong” prediction.
One specific type of boosting algorithm that is commonly used in sklearn is called “AdaBoost”. AdaBoost stands for Adaptive Boosting and is an iterative technique that weights the instances in the dataset in such a way that the classifier that was misclassified in the previous iteration is given more weight in the next.
There are several different types of boosting algorithms that can be used in sklearn, and each has its own strengths and weaknesses. However, one of the main advantages of boosting is that it often leads to models that are more accurate than those produced by a single classifier.
Multiclass classification means predicting one of several possible outcomes. For example, in the case of wine classification, there are red, white, and rose wines. In sklearn, we can use the OneVsRestClassifier, which creates multiple binary classifiers that can handle multiple classes.
In conclusion, boosting is an ensemble method for machine learning which can be very useful for classification problems like predicting the types of wine. AdaBoost is one of the most common boosting algorithm used in Sklearn, for multiclass classification we can use OneVsRestClassifier.
