Self driving cars, such as the ones being developed by companies like Google, have proven to be nearly crash-proof on their own. This is because computer programs make solid choices based upon true calculations. Also, programs simply don't get distracted like we humans do. Statistics show that nearly every single automobile accident involving self-driving cars was due to a human driver in another vehicle. In the one or two crashes where the self-driving car was at fault, it was simply because of something the programmer had done, in which such mistakes could easily be corrected later on.

Write a C program that reads two hexadecimal values from the keyboard and then stores the two values into two variables of type

Solution :

With,user receive recommendations for items that are similar in type to items they already like.

Dennis_Churaev [7]

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.

When you write a program that will run in a GUI environment as opposed to a

givi [52]

When you write a program that will run in a GUI environment as opposed to a

command-line environment, some syntax is different.

Explanation:

GUI (Graphical User Interface) which is the computer user interface uses graphical images to activate and run the applications.
Command line interface is a interface that is in a text format, which can accept commands for a task.
So, to program both interface, we need high level program skills with good understanding in programming languages like C++, C etc and algorithms.
Here, the GUI syntax differs from the command line interface.
