It comprises detailed information about how questions under ML challenges should be attempted and details about the HackerEarth judge.

Machine Learning challenge

1. Where will the challenge take place?

This challenge is an online challenge.

2. Will I receive a reminder notification before the challenge begins?

You will receive a reminder email 3 hours before the challenge begins only if you have registered for the challenge

3. How do I participate in this challenge?

To participate in this challenge, do the following:

1. Register for the challenge

2. Visit the challenge page on start date/time

3. Click Start now

4. How does the time limit work?

We follow an open time-limit format. In this format, you will have the following:

• Challenge duration

  • Duration between the start and end time of the challenge. For example, 24 hours (6 p.m. on Wednesday up to 6 p.m. on Thursday)

• Challenge-completion duration

  • Time within which you must complete the challenge. For example, within 12 hours (starting any time after 6 p.m. on Wednesday)
  • After you start the challenge, you cannot pause it

5. The challenge is open for 24 hours (6 PM on Wednesday up to 6 PM on Thursday). If I start the challenge on 5 PM on Thursday, how long will I get to complete the challenge?

This is a fixed event, which means that the duration is fixed. The challenge will end on the date and time that is given on the challenge page. The amount of time you will get to complete the challenge is based on when you begin the challenge.

If you register for and start the challenge on Thursday at 5 PM, you will get only 1 hour to complete the challenge.

6. How are the Machine Learning problems evaluated?

The evaluation is based on the evaluation metrics that are defined for a problem. When the challenge is live, your submission will be evaluated only for 50% of the test data.

After the contest is over, we re-evaluate and assign a score to your final submission based on the complete data set. Therefore, the score after the offline evaluation is subject to change.

7. How can I submit my final submission file?

You can submit your output by uploading your submission file on the Problems page in the format specified in the problem statement.

8. What all should I submit other than the submission file?

In addition to your submission file, you must submit the following:

• Text file explaining your approach to the problems
• Source files used to build your ML models

All these files should be submitted as a compressed archive in any one of these formats:

• zip
• tar
• zig

9. Which tools can I use for building my models?

You can use any tools or libraries for building your models. There is no restriction on thetools that you can use.

10. Where will the challenge take place?
