Identify the Problem:

We have Information of all previous general elections with respect to party, votes, Candidates, Locality, Issues in nation, etc. With All this information we need to find the winner of next general election.

Identify the problem:

We have information of all houses in a particular area like size, type and design of house, locality, colour, previous purchase etc. on the basis of these data we have to find the price of a particular house.

Identify a problem:

You have details of corona affected positive cases found in various regions. Depending upon parameters like number of increasing corona infected patients, weather conditions etc. regions are classified into red zone, Green zone and Orange Zone. On the basis of these data we have to predict the region of a city.

State whether True or False

The most meaningful and interpretable principal components are those that have the largest eigenvalues

Cross validation is used for

State True or False

For k cross-validation, larger k value implies more bias.

which of the following is not a method of cross validation?

If I am using all features of my dataset and I achieve 100% accuracy on my training set, but ~70% on validation set, what should I look out for?

Give the correct Answer for following statements.

1. It is important to perform feature normalization before using the Gaussian kernel.

2. The maximum value of the Gaussian kernel (i.e., ) is 1.

Which is/are method to do multiclass classification?

Following is Linear SVM classifier with 2 class classification problem. Now you have been given the following data in which some points are circled red that are representing support vectors.

If you remove the following any one red points from the data. Will the decision boundary change?

Suppose you are dealing with 4 class classification problem and you want to train a SVM model on the data for that you are using One-vs-all method. Now, say for training 1 time in one vs all setting the SVM is taking 10 second. How many seconds would it require to train one-vs-all method end to end?

For evaluating regression models, which of the following metrics can not be used ?

Suppose that we have N independent variables (X1,X2… Xn) and dependent variable is Y. Now Imagine that you are applying linear regression.You found that correlation coefficient for one of it’s variable(Say X1) with Y is -0.95.

Which of the following is true for X1?

Suppose that you have a dataset D1 and you design a linear regression model of degree 3 polynomial and you found that the training and testing error is “0” or in another terms it perfectly fits the data.

What will happen when you fit degree 4 polynomial in linear regression?

Which of the following function is used by Logistic Regression to convert the probability in between [0,1]

Regarding Bias and Variance ,which of the following statement is True?

Which of the following is true about Lasso and Ridge Regression?

Identify Performance measure P from following Traffic Pattern Analysis Algorithm.

____ % of Singaporeans will be over the age of 65 by 2030. [Only 1 answer is allowed]

Implications of Changing Demographics:

The make-up of Singapore society will be quite different just 15 years from now.

Social spending in Singapore has tripled to $ ____ billion(s ) over a decade. [Only 1 answer is allowed]

Implications of Changing Demographics:

The responsibility of supporting the elderly will fall on the next generation, & we are in turn responsible for helping them to rise up to this challenge.

The sharpest social divide in Singapore is now based on ____________ . [Only 1 answer is allowed]

Implications of Growing Social Divides:

Which of the job below is less unlikely to be automated in the future? [Only 1 answer is allowed]

Implications of a Changing Economy:

Job displacement is a real possibility, and while there will continue to be good jobs for our people in the future, they will look different from the jobs today.

The number of layoffs in Singapore in 2017 was about ____ % higher than in 2010.

Implications of a Changing Economy:

To prepare our students for the ever-changing world, we must enhance the learning environment to encourage continuous trying and learning from failure. This would develop our students’ intrinsic motivation to learn, and to continuously upgrade to stay competitive and relevant throughout their lives.

About ____ % of youth have a clear sense of what they want to do with their lives. [Only 1 answer is allowed]

Implications:

Most of our students are unlikely to have a clear idea of what they want out of life, & how to get there. Applied Learning allows our students to discover their interests & passions & are equipped with the dispositions & skills for learn for life, such as the need to imagine possibilities, takes risks, & learn from challenges & setbacks.

True or False: It is NOT important to offer some kind of motivation factor for Imagine Math goals

What must students complete in order for them to use the Live Teacher support feature?

What is the lesson plan resource that matches with the student achievement "measure" that is determined by taking Benchmark 1?

True or False: Being intentional with usage of student journals will make Imagine Math more meaningful.
