Challenge Problem

We ask fellows to work on a small challenge problem to assess problem solving and coding capabilities

Choose

Choose a challenge problem from a list provided to you when you login.

Analyze

Perform your analysis in a well-commented Jupyter notebook and post on Github or Google Colab.

Share!

Share your notebook with us.

Some hints for hacking our challenge

Ask yourself why would they have selected this problem for the challenge? What are some gotchas in this domain I should know about?

What is the highest level of accuracy that others have achieved with this dataset or similar problems / datasets ?

What types of visualizations will help me grasp the nature of the problem / data?

What feature engineering might help improve the signal?

Which modeling techniques are good at capturing the types of relationships I see in this data?

Now that I have a model, how can I be sure that I didn't introduce a bug in the code? If results are too good to be true, they probably are!

What are some of the weaknesses of the model and and how can the model be improved with additional work.

Video Submission

After finishing the challenge, we ask fellows to submit a brief video (not more than 7 minutes) on YouTube and share the link with us. The video should contain the following

Introduction - A short introduction to your background.

Motivation - Why do you want to participate in this program?

Analysis - Your analysis of the challenge problem that you submitted

Video Submission Guidelines

Please do not read from a script written beforehand.

Do not add any background music

Please ensure that the video is unlisted and not private

Challenge Problem Frequently Asked Questions

What are you looking for in challenge submissions?

Problem solving ability - did you understand the problem correctly, and did you take logical steps to solve it?
Machine learning skills - what sort of models did you use? How rigorous was your exploratory analysis of the data, your choice and fine tuning of models, and your assessment of results.
Coding skills - does your python look presentable or do you code like a scientist?
Communication skills - is your solution readable and well explained? Messiness and raw code with no explanation does not reflect well on your potential for working well with our business partners during the fellowship.

What are some of the common mistakes I should avoid?

Skipping exploratory analysis and feature engineering
Do not jump straight into fitting models without demonstrating to us, in your Jupyter notebook, that you have understood and thought about the dataset.
Choosing models with no explanation
Please use the notebook to explain your thought process. We care about this as much as we care about your results.
Unreadable notebooks
Make sure to run your notebook before sharing so that we can see the results. We won't be running your code on our machines. On the other hand, please do not print out the entire dataset or endless rounds of epochs.
Overly simplistic final results
Your final results should consist of more than a single number or percentage printout. Explain why you chose the success metrics you chose, and analyze what your output means.
