How Crisp Can you Classify? : A Data Challenge to flex your classification skills

Data Challenge Task

This Data Challenge has 2 tasks;

  • to determine the type of an Iris plant given data on sepal and petal lengths and widths of the flowers

  • to identify a digit/number given optical data from handwritten digits

Data Challenge Bounty

USD 100

to the highest ranked model submission, based on the Git timestamps

USD 10

to the next top 10 ranked submissions, based on Git timestamps

Invitation to an Exclusive Data Hackathon

Where we will hack on a real business’ data and stand a chance to win even more exciting prizes and learn from experienced mentors [this is for those based in or willing to travel to Nairobi]

Due Date: August 10th

Rules of Engagement

The Data Challenge is judged based on the following criteria:

  • A Correct fork, branch and pull request
  • Using the GitHub Pull Request timestamp where order of submissions is applicable
  • Using solution quality/accuracy and explanation to rank submissions where applicable
  • Do not share any code that you cannot open source on the Git Repository as its open source and african.ai will not be liable for any breach of intellectual property (if at all) once shared on the platform.

Working on the Data Challenge

1.Fork the code challenge repository provided.

2.Make a topic branch. In your github form, keep the master branch clean. When you create a branch, it essentially will be a copy of the master.

Pull all changes, make sure your repository is up to date

$ cd challenge1_HowCrispCanYouClassify
$ git pull origin master

Create a new branch as follows-> git checkout -b [your_phone_number_email], e.g.

$ git checkout -b 2348177779360_youremail@gmail.com master

See all branches created

$ git branch
* 2348177779360_youremail@gmail.com
  master

Push the new branch to github

$ git push origin -u 2348177779360_youremail@gmail.com

3.Remember to only make changes to the fork!

The folder named data contains 4 csv files.

  • iris_train
  • iris_test
  • digits_train
  • digits_test

The folder names submissions contains 2 csv files.

  • digits_sample_submission
  • iris_sample_submission

The train datasets contain labelled records, ie. their classes are known. In each case:

  • use the train datasets to train a satisfactory classification model
  • use the model to classify the records in the test datasets
  • ensure the format of your submission files is similar to the
  • once satisfied with the model and the predictions, name the file containing labelled test data iris_test_labelled or digit_test_labelled and include it in the submissions folder, submission files should include only 2 columns, the id and the predicted labels
  • Add to the base of the existing README file a brief explanation about your solution outlining the algorithm you chose to use, why you chose it and how the algorithm compared to any others you may have tried to use

4.Commit the changes to your fork.

5.Make a pull request to the challenge1_HowCrispCanYouClassify Repo.
