Online Machine Learning and Deep Learning Quiz (300+ Objective Type Questions)

I have created an online quiz on Machine Learning and Deep Learning. This quiz contains objective type questions on various concepts of Machine Learning and Deep Learning. 

Currently, there are 134 objective questions for machine learning and 205 objective questions for deep learning (total 339 questions). I will keep adding more and more questions to the quiz.

Rules and Guidelines

1. All questions are objective type questions with 4 options. Only one option is correct.

2. 60 seconds are allotted for each question.

3. Correct answer gives you 4 marks and wrong answer takes away 1 mark (25% negative marking).

4. We will take short breaks during the quiz after every 10 questions.

5. Passing score is 75%. Quiz contains very simple Machine Learning objective questions, so I think 75% marks can be easily scored.

6. Please don't refresh the page or click any other link during the quiz.

7. Please don't use Internet Explorer to run this quiz.

Helplines

There are 4 helplines given in this quiz:

1. Weed Out
2. Blink
3. Magic Wand
4. Hands Up













You can use one helpline per question except "Hands Up". You can use each helpline 4 times during the quiz. Below is the description of all these helplines:

1. Weed Out

"Weed Out" helpline weeds out two incorrect options. So, now you have to guess the answer only from 2 options from which one is the right answer.

2. Blink

Keep your eyes wide open while using the "Blink" helpline. "Blink" helpline first lights the bulb against the right option and then in fraction of a second (100 milliseconds), it goes on lighting the bulbs against wrong options. So you have to identify against which option, the bulb was lighted first.

3. Magic Wand

This is the most flexible helpline in which you have nothing to do. Just click on the "Magic Wand" and you get the right answer magically.

4. Hands Up

By using "Hands Up" helpline, you are not adding up score but saving your quiz time. You can use it as many times you want. I would suggest you to use this helpline when you have exhausted all your other helplines. If you find a question whose answer is not clear to you, and you don’t have any helpline left, please don’t waste time on that question and just raise your hands to save your time.

Next Question

Once you are done with the question, you can go to the next question by using this option.

Quit Quiz

Quiz contains a lot of objective questions on Machine Learning which will take a lot of time and patience to complete. If you feel tired at any point of time and don't want to continue, you can just quit the quiz and your results will be displayed based on the number of questions you went through.

Quiz Results

At the end of the quiz, you will get your score and time taken to complete the quiz. You can take screenshot of the result for any future reference.

  1. It would be useful to have a "next" button, or for it to go to the next question automatically once you answer the current one.
