Many people signup for their training. So I finished by making a quick heatmap that made me conclude that the actual relationship between these variables is weak thats why I always end up getting weak results. Some notes about the data: The data is imbalanced, most features are categorical, some with cardinality and missing imputation can be part of pipeline (https://www.kaggle.com/arashnic/hr-analytics-job-change-of-data-scientists?select=sample_submission.csv). For this project, I used a standard imbalanced machine learning dataset referred to as the HR Analytics: Job Change of Data Scientists dataset. Learn more. Thats because I set the threshold to a relative difference of 50%, so that labels for groups with small differences wont clutter up the plot. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. I got my data for this project from kaggle. Human Resource Data Scientist jobs. 5 minute read. Since our purpose is to determine whether a data scientist will change their job or not, we set the 'looking for job' variable as the label and the remaining data as training data. Simple countplots and histogram plots of features can give us a general idea of how each feature is distributed. The stackplot shows groups as percentages of each target label, rather than as raw counts. For another recommendation, please check Notebook. This dataset consists of rows of data science employees who either are searching for a job change (target=1), or not (target=0). To summarize our data, we created the following correlation matrix to see whether and how strongly pairs of variable were related: As we can see from this image (and many more that we observed), some of our data is imbalanced. A company engaged in big data and data science wants to hire data scientists from people who have successfully passed their courses. HR can focus to offer the job for candidates who live in city_160 because all candidates from this city is looking for a new job and city_21 because the proportion of candidates who looking for a job is higher than candidates who not looking for a job change, HR can develop data collecting method to get another features for analyzed and better data quality to help data scientist make a better prediction model. There has been only a slight increase in accuracy and AUC score by applying Light GBM over XGBOOST but there is a significant difference in the execution time for the training procedure. This dataset consists of rows of data science employees who either are searching for a job change (target=1), or not (target=0). Recommendation: The data suggests that employees with discipline major STEM are more likely to leave than other disciplines(Business, Humanities, Arts, Others). Training data has 14 features on 19158 observations and 2129 observations with 13 features in testing dataset. Light GBM is almost 7 times faster than XGBOOST and is a much better approach when dealing with large datasets. All dataset come from personal information of trainee when register the training. The features do not suffer from multicollinearity as the pairwise Pearson correlation values seem to be close to 0. Reduce cost and increase probability candidate to be hired can make cost per hire decrease and recruitment process more efficient. Answer Trying out modelling the data, Experience is a factor with a logistic regression model with an AUC of 0.75.
