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.
Answer: True
Explanation: CCM process is the process which basically watches over any change or modification that is being made in the data and it will only be implemented when there is no adverse effect of the change.It procedure helps in reducing the risk due to any modification made in data of a system. CCM process also take care of the confidentiality of data and integrity as well and helps inn maintaining it.Therefore the given statement is true.
Answer:
The Pointer P becomes a dangling pointer.
Explanation:
int calculate(){
int *p = (int*)malloc(10);
*p = 10;
return p;
}
In this program, the scope of p is only with the calculate function block. Hence, once the compiler comes out of the function, it can no more access the pointer p or the memory location p is pointing to. To overcome the dangling pointer, we need to declare p as static, so that the scope of p is throughout the program.
Answer:
The capacity of the disk is "40 GB".
Explanation:
Given value:







Cache memory is often used to speed up the runtime. It will enable us to improve performance unless we can store information, that is retrieved constantly in memory space.
- Hit Cache: when the Processor relates to representing database data, Cache Hit results.
- Miss Cache: when this Processor responds to a non-present cache data, this will trigger its miss of cache.
- It doesn't have to retrieve the Main Memory through secondary storage.
