Do years of experience has any effect on the desire for a job change? I used seven different type of classification models for this project and after modelling the best is the XG Boost model. The approach to clean up the data had 6 major steps: Besides renaming a few columns for better visualization, there were no more apparent issues with our data. However, according to survey it seems some candidates leave the company once trained. 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. For the full end-to-end ML notebook with the complete codebase, please visit my Google Colab notebook. XGBoost and Light GBM have good accuracy scores of more than 90. Hence to reduce the cost on training, company want to predict which candidates are really interested in working for the company and which candidates may look for new employment once trained. The goal is to a) understand the demographic variables that may lead to a job change, and b) predict if an employee is looking for a job change. Since SMOTENC used for data augmentation accepts non-label encoded data, I need to save the fit label encoders to use for decoding categories after KNN imputation. Not at all, I guess! Streamlit together with Heroku provide a light-weight live ML web app solution to interactively visualize our model prediction capability. In other words, if target=0 and target=1 were to have the same size, people enrolled in full time course would be more likely to be looking for a job change than not. The whole data is divided into train and test. Introduction. Information related to demographics, education, experience are in hands from candidates signup and enrollment. Variable 2: Last.new.job Further work can be pursued on answering one inference question: Which features are in turn affected by an employees decision to leave their job/ remain at their current job? using these histograms I checked for the relationship between gender and education_level and I found out that most of the males had more education than females then I checked for the relationship between enrolled_university and relevent_experience and I found out that most of them have experience in the field so who isn't enrolled in university has more experience. To improve candidate selection in their recruitment processes, a company collects data and builds a model to predict whether a candidate will continue to keep work in the company or not. Learn more.

The simplest way to analyse the data is to look into the distributions of each feature. What is the effect of company size on the desire for a job change? I got -0.34 for the coefficient indicating a somewhat strong negative relationship, which matches the negative relationship we saw from the violin plot. March 9, 20211 minute read. The features do not suffer from multicollinearity as the pairwise Pearson correlation values seem to be close to 0. Second, some of the features are similarly imbalanced, such as gender. 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. Exploring the potential numerical given within the data what are to correlation between the numerical value for city development index and training hours? Variable 3: Discipline Major well personally i would agree with it. So I went to using other variables trying to predict education_level but first, I had to make some changes to the used data as you can see I changed the column gender and education level one.
