Answer:

Collaborative filtering

Explanation:

This is one out of five on the Recommender system apart from most popular items, Association and Market Basket based Analysis, Content-based analysis, self and hybrid analysis where we use both content-based and collaborative based approach together. And the Recommender system is a very important topic in Data science. For this question, remember that Collaborative filtering focuses on user and various other user's choices which are mathematically alike to concerned users, and which we find with the study of a large data set. Thus, we can predict from our above study that what are going to be likes of concerned users, and at the item level, whether that item will be liked by the concerned user or not. And this is prediction, and we use this approach in Machine learning these days. For this question, and as mentioned in question the requirements, answer is Collaborative filtering.

Marina CMI [18]

Answer:

i. This value was not accepted because we have 12 months and not 13.

ii. This is because the user entered the value for the day as value for the month.

Explanation:

i. Why was this not accepted?

This value was not accepted because we have 12 months and not 13. The user entered a value that was above the maximum value registered for the number of months in a year- which is 12.

ii. Why do you think this error occurred

This is because the user entered the value for the day as value for the month.

This could be because the user uses a date system different from that of the program.
