Answer:
b
Explanation:
First, we need to initialize the classifier.
Then, we are required to train the classifier.
The next step is to predict the target.
And finally, we need to evaluate the classifier model.
You will find different algorithms for solving the classification problem. Some of them are like decision tree classification etc.
However, you need to know how these classifier works. And its explained before:
You need to initialize the classifier at first.
All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.
The predict(x) returns the y which is the predicted label.And this is prediction.
For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.
Answer:
Option (B) is the correct answer of this question.
Explanation:
Packet analyzer is a software application or set of infrastructure capable of unencrypted and recording communication that travels through a virtual system of a computer system.A packet analyzer used to detect network activity is recognized as a broadband monitoring system.
A packet analyzer is a code application that is used for monitoring, intercepting, and recording http requests with the help of a virtual interface.
Other options are incorrect because they are not related to the given scenario.
Answer:
function validateForm(event)
{
event.preventDefault();
var phoneNumber = form.phoneNumber.value;
var userName = form.userName.value;
if(phoneNumber.length!=10)
console.log("Phone Number is Invalid");
if(userName.length<11)
console.log("User Name is Invalid");
}
Answer:
A. Big Data
Explanation:
It is big data. The internet searches, customer transactions, social media posts, medical tests, weather sensors, military surveillance, and all the data source you are seeing around yourself forms together with the big data. And a big social media company gathers around so many petabytes of data each day. And there are so many such companies, plus all sorts like eLearning sites, etc. And all these together form the big data.
Answer: b. 11
Explanation:
//The initial value is 1
//let call the value as x
x = 1
//then the user updated the value to 10
//so now x is 10
x = 10
// and update the workflow to 11
//so now the value of x is 11
x = 11
even if the programmer print x, so the output will be 11
