1. Precision and recall are two numbers which together are used to evaluate the performance of classification or information retrieval systems. Precision is defined as the fraction of relevant instances among all retrieved instances. Recall, sometimes referred to as ‘sensitivity, is the fraction of retrieved instances among all relevant instances. A perfect classifierhas precision and recall both equal to 1. It is often possible to calibrate the number of results returned by a model and improve precision at the expense of recall, or vice versa. Precision and recall should always be reported together. Precision and recall are sometimes combined together into the F-score, if a single numerical measurement of a system's performance is required.

1. Note about upcoming changes to our XCS229 professional courses: Currently, the professional offering of the Stanford graduate course CS229 is split into two parts—Machine Learning (XCS229i) and Machine Learning Strategy and Reinforcement Learning (XCS229ii). Beginning in Spring 2022, material from CS229 will be offered as a single course (XCS229), in line with all other courses in the program. The new course will include all topics in XCS229i and XCS229ii, but will not include the final project which is currently part of XCS229ii. If you have taken XCS229i in the past you may still enroll in the final cohort of XCS229ii, which begins October 4, 2021. In this era of big data, there is an increasing need to develop and deploy algorithms that can analyze and identify connections in that data. Using machine learning (a subset of artificial intelligence) it is now possible to create computer systems that automatically improve with experience. This technology has numerous real-world appli...

1. By definition, precision is the proportion of correctly identified positive labels (TP) among all the predicted positive labels (TP + FP). Because low FP yields high precision, precision is an excellent metric when minimizing false-positives takes priority(e.g., a spam filter misidentifies legitimate emails as spam). However, when the positive cases are rare, precision alone is not enough to warn us against the case of high false negatives.

Frequently Asked Questions

What is the difference between precision and recall?

Precision and recall In pattern recognition, information retrieval and classification (machine learning), precision (also called positive predictive value) is the fraction of relevant instances among the retrieved instances, while recall (also known as sensitivity) is the fraction of relevant instances that were retrieved.

How do you calculate precision and recall?

Recall is defined as the number of relevant documents retrieved by a search divided by the total number of existing relevant documents, while precision is defined as the number of relevant documents retrieved by a search divided by the total number of documents retrieved by that search.

What is precision and recall?

precision and recall (or “PR” for short – not to be confused with personal record, pull request, or public relations) are commonly used in information retrieval, machine learning and computer vision to measure the accuracy of a binary prediction system (i.e. a classifier that maps some input space to binary labels,...

What is precision score?

With precision scores in general, the lower the score the higher the risk for the lender, the higher the interest rate charged. Credit model names differ, but credit rating agencies use comparable algorithms. The score determines risk for a lending institution to lend money or advance credit to borrowers.
