Byte pair encoding is a data encoding technique. The encoding algorithm looks for pairs of characters that appear in the string

more than once and replaces each instance of that pair with a corresponding character that does not appear in the string. The algorithm saves a list containing the mapping of character pairs to their corresponding replacement characters.
For example, the string "THIS_IS_THE_BEST_WISH" can be encoded as "%#_#_%E_BEST_W#H" by replacing all instances of "TH" with "%" and replacing all instances of "IS" with "#".
Which of the following statements about byte pair encoding is true?
A. Byte pair encoding is an example of a lossy transformation because it discards some of the data in the original string.
B. Byte pair encoding is an example of a lossy transformation because some pairs of characters are replaced by a single character.
C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.
D. Byte pair encoding is an example of a lossless transformation because it can be used to transmit messages securely.

Answer:

C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.

Explanation:

Byte pair encoding is a form of encoding in which the most common pairs of consecutive bytes of data are replaced by a single byte which does not occur within the set of data.

For example, if we has a string ZZaaAb, it can be encoded if the pairs of string ZZ are replaced by X and the second pair by Y. So, our data now becomes XYAb.

To get our original data, that is decode it, we just replace the data with the keys X = ZZ and Y = aa thus allowing our original data to be restored.

Since our original string is restored without loss of data, it implies that <u>byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.</u>

Identify the type of error described
Arturiano [62]

Answer:

ZeroDivisionError

ValueError

Explanation:

ZeroDivisionError occurs when you attempt to divide a number by 0.

ValueError occurs when the argument passed into a function holds the wrong value. In this case, the string is not numeric which cannot be passed into the float() function.

Hope this helps :)

An Agile Team decides they want to use pair programming in future Iterations. Where should this be captured? g
Umnica [9.8K]

Answer:

The decision to use pair programming by an Agile Team should be captured in their <em>Inspect and Adapt meeting notes.   </em>

Explanation: The underlying principle for having an agile team that the team is committed to constant incremental and or progressive improvement.

Inspect and Adapt Meeting Notes are notes which hold the summary of past achievements which hold and records of things to do going forward in order to ensure that there is progress and improvement over the last set of objectives.

These notes are usually taken at the Inspect and Adapt meeting. This is simply a meeting held at the end of each project milestone. An agile team during this meeting will review its performance, agree and document how it can be more effective.

Pair programming is also an Agile practice in the parlance of software development. Instead of the regular method where an individual is tasked with the development of an application, in this case, two programmers are tasked with the development of one App.

Sometimes this method is used during Extreme Programming (XP)

Cheers!

iragen [17]

Answer:

False.

Explanation:

The description provided matches better with Software performance testing, and shouldn't be confused with a benchmark.

In computing, a benchmark is a tool or software designed to measure the average performance of another program, by running several tests and trials against it.

A performance testing is designed to measure the performance and responsiveness of a computer system (not a program) under a heavy workload.
