Answer:

A for loop can be used to make something repeat as many times as you program it to, but a while loop only stops when you complete the task, or a certain condition is met. So, if you program a for loop to fill a bucket six times it will fill the bucket six times.

Assume that the int variables i and j have been declared, and that n has been declared and initialized.

Sonja [21]

Answer:

The code to this question can be given as:

code:

for(i=1;i<=n;i++) //for loop column

{

for(j=1;j<=i;j++) //for loop for rows

{

printf("*"); // print asterisks

}

printf("\n"); //line break

}

Explanation:

We know that variable i,j, and n is already declared and n variable has initialized a value. So, we write the code that is given above. In this code, we use a nested loop. In this code, we use two loops that are a loop (i)for column and j loop for rows. for print asterisks triangle we use two for loop. For that, we use two-variable (i,j) that is already declared. We assign the value in (i) loop that is 0 and checks that (i) is less than equal to n and increment of (i) by 1. In this loop, we use another loop that is (j) loop. It also starts from 1 and checks that (j) is less than equal to (i)and increment of (j) by 1. In that loop, we print asterisks end of (j) loop. In (i) loop we use ("\n") for line break end of (i) loop.

You’ve just finished training an ensemble tree method for spam classification, and it is getting abnormally bad performance on y

inn [45]

Answer:

The various reasons that could be a major problem for the implementation are it involves a large number of parameters also, having a noisy data

Explanation:

Solution

The various reasons that could be causing the problem is given as follows :

1. A wide number of parameters :

In the ensemble tree method, the number of parameters which are needed to be trained is very large in numbers.

When the training is performed in this tree, then the model files the data too well.

When the model has tested against the new data point form the validation set, then this causes a large error because the model is trained completely according to the training data.

2. Noisy Data:

The data used to train the model is taken from the real world . The real world's data set is often noisy i.e. contains the missing filed or the wrong values.

When the tree is trained on this noisy data, then it sets its parameters according to the training data.

As regards to testing the model by applying the validate set, the model gives a large error of high in accuracy y.
