Machine Learning Challenge - Chaordic

Machine Learning Challenge from Chaordic


Steps to solve the challenge

  1. Gathering information: research similar problems and published articles

  2. Knowing the data: play with the datasets and see how it is structured

  3. Cleaning the data: split the dataset and remove irrelevant information

  4. Analysing the data: find correlations between possible features and the target data

  5. Training the model: split the data for train and test and try different models of classifiers

  6. Evaluating the model: compare the results with an appropriate metric for a binary classification

  7. Submitting the answer: generate csv file with the target data scored with the best trained model

  8. Iterating over the process: go back to step 4, filter the relevant features, remove outliers, balance the trainig data, combine some variables, do some magic, ...


Tools used during the challenge

  1. Gathering information: google

  2. Knowing the data: gedit and bash commands

  3. Cleaning the data: bash scripts and OpenRefine

  4. Analysing the data: jupyter notebooks and python libraries (pandas, numpy, matplotlib, ...)

  5. Training the model: sklearn modules

  6. Evaluating the model: sklearn functions and methods inside classes

  7. Submitting the answer: python code

  8. Iterating over the process: try different tools like azure machine learning studio
