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))
Answer:
it can balance computing resources by time
Explanation:
this this is as it involves multiprogramming
Answer:
real-time analytics
Explanation:
Real time analytics is a type of data analysis that is done immediately the data for analysis is available. This can allow users to draw conclusion or acquire new insights swiftly and immediately the data enters their system. Businesses use real time analytics when there is a need to make and execute new decisions without hesitation.
A business that wants to centralize its administrative tasks and simultaneously wants the existing system to manage and sustain the growing amount of work in a capable manner would use real-time analytics.
