In the context of the components of a typical expert system, _____ is similar to a database, but in addition to storing facts and figures it keeps track of rules and explanations associated with facts.

Answers

Answer 1

Answer:

Knowledge base.

Explanation:

Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.

Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.

Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;

I. Non-algorithmic processing.

II. Symbolic processing.

In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.

Hence, expert systems represents knowledge as a set of rules by mimicking the expertise of humans in a particular field to uniquely proffer solutions to a problem.

Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.

Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.

Basically, expert systems comprises five (5) main components and these are;

1. Explanation module.

2. Inference Engine.

3. Knowledge acquisition and learning module.

4. User Interface.

5. Knowledge Base.

In the context of the components that makes up an expert system, knowledge base is similar to a database because it is used for storing facts and figures, while keeping track of rules and explanations associated with facts. Thus, giving rise to the knowledge base management system (KBMS).

Answer 2

In the context of the components of a typical expert system, Knowledge base is similar to a database, but in addition to storing facts and figures, it keeps track of rules and explanations associated with facts.

An expert system is a form of artificial intelligence where computer imitate the decision making style of humans.

There are basically two types of the expert system and they are the inference engine and the knowledge base.

The knowledge base consists of the facts and rules and ways of interpreting them to arise to new insights. The inference engine applies logical rules to the knowledge base.

cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:

Answers

Answer:

#include <iostream>

int main() {

 // The length of the list

 int l;

 // The array containing the numbers

 int *list;

 // Threshold, last value in array

 int thresh;

 

 // Read in first value and create an array with the size of that value

 scanf("%d", &l);

 list = (int*) malloc(l * sizeof(int));

 

 for(int i = 0; i < l; i++) {

   scanf("%d", &list[i]);

 }

 thresh = list[l - 1];

 // Print the values

 for(int i = 0; i < l - 1; i++) {

   if (list[i] <= thresh) {

     printf("%d ", list[i]);

   }

 }

 

 printf("\n");

 free(list);

}

Explanation:

The program assumes at least two values are provided. The length of the list and the threshold.

We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.

Write the code for the following problem.
Add a function to problem to display the last name and highest, last name and lowest and average exam score. Hint: for highest initialize a variable to 0 (high_var). If the array value is higher than the high_var then set high_var to the array value and set high_index to the position of the array. Proceed through the array until you get to the end. Do the same for finding the lowest using low_var set to 999 (higher than the highest value). For the average score, sum all the exam scores as you proceed through the loop. Use a for loop to go through each occurrence of the arrays. Note you can do all this with one for loop but if it makes more sense to you to use multiple for loops that is ok too.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.

A hammer tool can only be used by one technician at a time to perform hitting. Accordingly, you have developed a Hammer class with a hit method. Objects of class Hammer are used to simulate different hammers, while threads are created to simulate users. Which situation needs to add the synchronized keyword to the hit method

Answers

Answer:

Explanation:

The synchronized keyword needs to be active on the hit method at any point where 2 or more threads (users) exists at any given moment. This is in order to prevent two or more users from trying to perform a hammer hit at the same time. This is what the synchronized keyword is used for. It prevents the more than one thread from calling the specific method at the same time. Instead it adds the action to a sequence so that the second thread calls the hit method only after the first thread's hit method finishes.

If you were driving the blue Prius in the situation pictured above, explain why the red Mustang should be given right-of-way at this intersection.

Answers

Answer:

The red Mustang should be given the right-of-way at this intersection because:

The red Mustang arrived first before the blue Prius and is closer to the stop sign before the arrival of the blue Prius.  This implies that the red Mustang must have waited for its turn, unlike the blue Prius that just arrived at the intersection.

Explanation:

Traffic laws, regulations, and IPDE defensive driving strategy require that drivers always give way to the vehicle that arrived before them at an intersection.   Assuming that multiple vehicles reach the intersection simultaneously, then the vehicle must be given the right-of-way.  Alternatively, the traffic lights at the intersection should be obeyed and be allowed to regulate the movement of vehicles.  IPDE defensive driving strategy requires drivers to be watchful of their driving spaces to determine the appropriate time to move.

Our graphic can look good at any resolution, no matter how large it gets. If we take a png or jpg file and make it extremely large, you'll notice the image begins to get blurry, because the pixels are being stretched and colors are being predicted or matched for the larger scale.

A. A "for" loop inside of a "while" loop
B. A "while" loop inside of a "for" loop
C. None of the above

Answers

The type of nested loop which I would use to write the program is:

B. A "while" loop inside of a "for" loop

What is a Loop?

This refers to the control flow statement which is used to iterate and lets a particular line(s) of code execute repeatedly

With this in mind, we can see that the type of nested loop which I would use to write the program is a "while" loop inside of a "for" loop because it is a conditional statement that continues to ask for the certain valid grades until it gets the right one.

Therefore, the correct answer is option B

Suppose you have a stack ADT (i.e., an Abstract Data Type that includes operations to maintain a stack. Design a flowchart or suitable logical diagram to show you could implement a queue’s enqueue and dequeue operations using two stacks, stack 1 and stack 2.

Answers

Answer:

One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.

Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).

Dequeueing would be:

- For all items in stack1: pop them from stack1 and push them in stack 2.

- Pop one item from stack2, which will be your dequeue result

- For all items in stack2: pop them from stack2 and push them in stack 1.

Hope it makes sense. I'm sure you can draw a diagram.

How to use the AI System ?

ANSWER:

· New artificial intelligence systems are being developed to help teachers administer more effective testing that could uncover some of these often-hidden conditions. Once they can be properly identified, educators can tap into the resources available for a learning disability. Students can use AI to give reliable feedback.

1. For this assignment you will print the steps for 8-bit by 8-bit multiplication.
2. Your program should read in two unsigned numbers from stdin, the first being the multiplicand and the second being the multiplier. Your program should verify that both values are within the range 0 to 255. If not, the program should print an appropriate error message and exit.
3. Your program should then initialize the simulated registers and echo the input values in decimal and also in binary.
4. Then your program should illustrate the eight steps required for multiplication using the same type of step diagrams as given in the lecture notes.
5. Finally, your program should print a check section that shows a summary of the multiplication in binary as well as in decimal. See the example below.
6. You may write your program in C, C++, or Java. If you choose to work in C, here is an example function that will allow you to represent an n-bit value within an int data type and print out the binary value in "length" bits. It uses the shift right operator and the bitwise and. (You can also choose to use unsigned int as the data type; since you are using only the lower 8 of the 32 bits in an int, there will be no apparent difference between using int and using unsigned int. However, if you choose to use char as the data type, you should use unsigned char to ensure that the compiler generates logical rather than arithmetic shifts.)
void prt_bin( int value, int length ){
int i;
for( i=(length-1); i>=0; i--){
if((value>>i)&1)
putchar('1');
else
putchar('0');
}
}
For example, if you declare acc as an int, then you could call prt_bin(acc,8) to print the 8-bit value in the accumulator.
You should format your output to exactly match the output below. 10% of the grade will be awarded for following the same format.
