top i believe is the answer
Answer:
The third point i.e " Use an alternating least squares (ALS) algorithm to create a collaborative filtering solution" is the correct answer .
Explanation:
The Alternating Less Squares is the different approach that main objective to enhancing the loss function.The Alternating Less Squares process divided the matrix into the two factors for optimizing the loss .The divided of two factor matrix is known as item matrix or the user matrix.
- As we have to build the machine learning model which proposes restaurants to restaurants that are based on the customer information and the prior restaurant reviews the alternating least squares is the best model to implement this .
- All the other options are not the correct model also they are not related to given scenario that's why they are incorrect options.
In python:
first_grade = float(input("Please input the first grade "))
second_grade = float(input("Please input the second grade "))
third_grade = float(input("Please input the third grade "))
print("The average of the three grades is {}".format( round((first_grade + second_grade + third_grade) / 3,2)))
Answer:
Option e: The use of programmed decisions should be limited to noncritical situations.
Explanation:
A repetitive decision or routine that can be managed by developed business procedures or rules are known as programmed decisions. These kind of decisions are most often known for at certain points in a standard process, and are planned relying on recognized and easily identifiable terms. Programmed decisions generally do not demand much consideration or discussion, and can typically be automated to make certain consistency and save time for decision-makers.
So, the use of programmed decisions should not be limited to noncritical situations.
Keeping the fact in mind that Sasha wants to work as a program developer of iPhone applications, she will have to make use of the native language Objective-C.
Objective-C
<u>Explanation:</u>
The iPhone applications and interface work on iPhone Operation System or IOS, that make them completely different from the android and other operating systems currently being used in smartphones.
Moreover, Apple Inc. took a decision to use native languages like Objective-C for application development in the IOS environment because it cost them less as compared to other languages and the performance parameter also stands high and unaffected.
