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.

Explanation:

In programming variables exists with scopes This could be local or global. When a variable is declared as a global variable it is available to all methods and procedures in the program. Java programming language as well as C++ and several others use the open and close braces to define the scope in programs. consider the following example

<em>public class ANot {</em>

<em>    public static void main(String[] args) {</em>

<em>        int i = 0;</em>

<em>        while ( i<10){</em>

<em>            int sum = 0;</em>

<em>            sum = sum+i;       </em>

<em>        }</em>

<em>    }</em>

<em>}</em>

In this example, the variable i is global and can be assessed within the while loop but the variable sum is local to the while loop and cannot be assessed outside of it
