Select Your Challenge
Our challenge problems help us understand your aptitude for the program. These are not meant to be overly challenging and participants don't need previous machine learning or data science experience to complete them successfully. Your approach to these challenges help us understand your capabilities in problem solving and rapidly acquiring and demonstrating new skills.
Pick one of the following challenges. Perform your analysis in a Google Colaboratory Notebook and share your results 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 types of visualizations will help me grasp the nature of the problem / data?
- What are some of the weakness of the model and and how can it be improved with additional work?
You can learn more about Google Collaboratory here.
Fit a regression model (with an out-of-sample R^2 of >0.01) to a financial time series. Financial series have a low signal-to-noise ratio, so even a weak correlation will require some basic feature engineering (moving average prices, volatility, etc).
Basic Computer Vision
Modify the Keras MNIST example to train a single decision tree model. Show the training / validation accuracy of your model.
