A classifier is any algorithm that sorts data into labeled classes, or categories of information. A simple practical example are spam filters that scan incoming raw emails and classify them as either spam or not spam. Classifiers are a concrete implementation of pattern recognition in many forms of machine learning.
Most classifiers produce a score, which is then thresholded to decide the classification. If a classifier produces a score between 0.0 and 1.0 , it is common to consider anything over 0.5 as positive.

Classifier: A classifier is a special case of a hypothesis . A classifier is a hypothesis or discrete valued function that is used to assign class labels to particular data points.
In pattern recognition, information retrieval and classification , precision is the fraction of relevant instances among the retrieved instances, while recall is the fraction of relevant instances that were retrieved.
There are two kinds of indicators that can be used to estimate the quality of classification models: Quantitative quality indicators statistics which express the quality of classification using numerical values. Graphical indicators the quality of classification is represented on a graph which combines selected quantitative indicators.
With the output of the tools and the values of the classification the machine learning techniques are used to make a decision tree based text classifier to detect ambiguities in the documents. This work has similarity aspects to our work, but the difference is that it only detects ambiguous passages in SRS documents.
Therefore, I decided to apply some machine learning models to figure out what makes a good quality wine! For this project, I used Kaggles Red Wine Quality dataset to build various classification models to predict whether a particular red wine is good quality or not. Each wine in this dataset is given a quality score between 0 and 10.
