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:
The answer of the following question is Encryption.
Explanation:
Encryption is the second layer of the OSI Layer. It helps reduce the maintenance charges and offload complexity.
Encryption has presents in layer 3 and layer 4 which is IPSec in layer 3 and SSL, TSL in layer 4. of OSI Model.
<u>Note</u>- Only the Encryption can protect the data itself
here are some ideas
some things i wished i knew before coming into middle school:
1. be organized
2. dont worry about other peoples opinions
3. DO YOUR HOMEWORK

Answer and Explanation:
1. There’s need to ask for help and advice from people who have the
knowledge and skills in making a simple electrical gadget.
2. Adapter is used to plug appliances that are far from the main power source.
3. Do not touch the metal pipes while you are doing electrical repairs.
4. Shut off the power at the main switch or circuit breaker and unplug the equipment when working on electricity.
5. Pliers are tools used to grip, pull or cut electric wires.
From the above, we have corrected some of the errors that could be made in everyday home appliances or home electricity. In number 4, it is also worthy of note that shutting off power at the main switch will only require emergency situations otherwise we need only shut off the one for the problem circuit and leave the rest.
The
Insert Tab option
You can add a shape your word, excel or PowerPoint document to
make a drawing. To do this in MS Word, click on the Insert tab, and in the illustration
group, click on the shapes option. Click the shapes or callouts that you would
like to insert and then drag to place the shape anywhere in the document.
