Naive Bayes Classification explained with Python code
Machine Learning is a vast area of Computer Science that is concerned with designing algorithms which form good models of the world around us (the data coming from the world around us).
Within Machine Learning many tasks are – or can be reformulated as – classification tasks.
In classification tasks we are trying to produce a model which can give the correlation between the input data and the class
each input belongs to. This model is formed with the feature-values of the input-data. For example, the dataset contains datapoints belonging to the classes Apples, Pears and Oranges and based on the features of the datapoints (weight, color, size etc) we are trying to predict the class.
We need some amount of training data to train the Classifier, i.e. form a correct model of the data. We can then use the trained Classifier to classify new data. If the training dataset chosen correctly, the Classifier should predict the class probabilities of the new data with a similar accuracy (as it does for the training examples).
After construction, such a Classifier could
