The reason why computers has the need to periodically check
for the DNS of websites that an individual has already visited because certain
websites can change its IP address and that the individual using it can be
directed to a different website that he or she does not know of.
Answer and Explanation:
Some of the advantages of using the F measure (weighted harmonic mean) over using the Precision & Recall when evaluating an IR system performance are as follows-
- Precision quantifies the number of positive class predictions that actually belong to the positive class.
- Recall quantifies the number of positive class predictions made out of all positive examples in the dataset.
- F-Measure provides a single score that balances both the concerns of precision and recall in one number.
- A measure that combines precision and recall is the harmonic mean of precision and recall, the traditional F-measure or balanced F-score:
F=2((precision.recall)/(precision+recall))
