    The analytic methods can improve Human Resources (HR) management for companies with large number of employees. It is very easy to give example, how can companies benefit from machine learning methods applied to HR. Let’s assume that training of new employee costs 1000$ and if we can predict which employee is going to leave next month, and propose him/her a bonus program worth 500$ to keep him for next 6 months, we are 500$ on plus and keep experienced, well-trained employee under the hood, with higher morale.

    Herein the performance of MLJAR on Kaggle dataset from “Give me some credit” challenge is reported. The obtained results are compared with other predictive APIs from Amazon, Google, PredicSis and BigML. This post was inspired with Louis Dorard’s article.

  • Predict stock market on AI tournament (numer.ai)

    September 28, 2016 by Piotr Płoński

    The data and machine learning models used by hedge funds are secret. However, there is one hedge fund which makes its data public - Numer.ai. The dataset is encrypted and prediction of stock market is transformed into binary classification problem. Every 7 days (one round) a new dataset is released and anyone can download it, train model and upload predictions. At the end of the round, the best predictions are rewarded - there is no need to upload the model. As you can see from the leaderboard, MLJAR_COM is doing really well!
