End-To-End Business Projects. Employee turnover attrition is a major cost to an organization, and predicting turnover is at the forefront of needs of Human Resources HR in many organizations. Until now the mainstream approach has been to use logistic regression or survival curves to model employee attrition. However, with advancements in machine learning MLwe can now get both better predictive performance and better explanations of what critical features are linked to employee attrition.

His statement cuts to the core of a major problem: employee attrition. An organization is only as good as its employees, and these people are the true source of its competitive advantage. Organizations face huge costs resulting from employee turnover. Some costs are tangible such as training expenses and the time it takes from when an employee starts to when they become a productive member.

However, the most important costs are intangible.

With advances in machine learning and data science, its possible to not only predict employee attrition but to understand the key variables that influence turnover.

Machine Learning with h2o. This has all changed with the lime package. The major advancement with lime is that, by recursively analyzing the models locally, it can extract feature importance that repeats globally. What this means to us is that lime has opened the door to understanding the ML models regardless of complexity. Now the best and typically very complex models can also be investigated and potentially understood as to what variables or features make the model tick.

With these new automated ML tools combined with tools to uncover critical variables, we now have capabilities for both extreme predictive accuracy and understandabilitywhich was previously impossible!

You can download the data and read the analysis here:. The article shows that using Watson, the analyst was able to detect features that led to increased probability of attrition. Download the data here. This is needed for H2O. We could make a number of other numeric data that is actually categorical factors, but this tends to increase modeling time and can have little improvement on model performance.

We can see all of the columns. We are going to use the h2o. Next, we change our data to an h2o object that the package can interpret.

We also split the data into training, validation, and test sets. Now we are ready to model. The features every other column are what we will use to model the prediction.And, Seattle is the go-to location for C programmers, based on public Github data? In India, Bangalore is the top hub for coding talent, wherein Java has the most Github repositories. This is in sharp contrast to patterns seen in most US cities, where Java falls into the fourth slot, after Javascript, Python, and Ruby.

These are useful insights for HR talent teams. What are some interesting findings for employee engagement? A leading Asian retail bank found that employee stock option ESOP was the strongest influencer of employee performance in annual reviews, specifically in certain business units. The bank also found that employees engaged in company CSR activities exhibited the least risk of attrition. Insights such as these demonstrate that data can help surface the apparently invisible, but stronger undercurrents of human behavior.

Data analytics can be a potent tool to better understand employees and their engagement levels. It can transform the length and breadth of the HR function. It can come in handy to reduce hiring bias, improve employee relationships, find drivers of performance, and help manage attrition.

HR processes capture a wealth of data. They start from initial contact and extend long after employees move out of active engagement.

This data can provide particularly valuable nuggets of actionable insights. When enriched with the right external sources, it can turn into a goldmine.

Here are 3 steps for success in the journey towards smarter talent management. Lack of data or curated sources is a common complaint in organizations. This is often cited for slow progress in making HR more data-driven.

People quote how the entire function is driven by excel sheets. Or how pulling together a single employee view is tough, despite decades of digitization. There are numerous data trails that org systems generate. Imagine biometrics, CCTV feeds, intranet logs or sensor-enabled smart offices. All of this data can be harvested without trampling upon privacy or ethics.

If you typeWhen I first started learning about the use of big data in HR, I thought it was going to be just a waste of time. My initial impression was that it will take too much time for a bunch of weak and uncertain results. However, I soon realized that HR analytics actually derives a number of meaningful conclusions from what previously seemed like a big pile of useless data.

People analytics, when effectively used, gives HR the ability to provide substantive information allowing the business they support to reap significant commercial gains. Now, this is something that really deserves a proper explanation after all.

In this article, we are going to explain the process of big data analytics in the field of human resources. With the markets being crowded with dozens or even hundreds of serious competitors, companies are really struggling to attract the most talented young professionals. Traditional HR management cannot handle this issue properly due to the lack of manpower or simply because it is not able to analyze so many information at the same time.

Using data science and contemporary software solutions related to talent acquisition management, companies are able to filter through thousands of resumes and create a base of the most promising prospects.

After this first round of selection is completed, it is getting easier for HR teams to analyze each applicant individually and to choose the candidates that they should invite to the interview.

Without help from big data analytics, this process would take much more time and would still end up being less precise and efficient. The real job is to introduce them to their new duties and guide them through professional training programs.

First of all, they need to adapt to corporate procedures and then to learn all details about their positions and software solutions that they are going to use at work. When this phase is over, it is necessary to keep learning because the vast majority of businesses are constantly upgrading their services. Employees often attend online courses, training sessions, and other learning programs. However, it is hard to determine the exact benefits of such procedures. Namely, many companies realized that the cost of training is much higher than the profit they receive out of it.

This is how companies get the best evaluation and then have the opportunity to modify courses in order to make them more productive. This system enables an organization to monitor all key performance indicators in real time and to evaluate each one of its workers separately.

Big data analysis also detects potential mistakes and flaws in work, which is a valuable feedback that can be used to make things right in short notice.We also measure the accuracy of models that are built by using Machine Learning, and we assess directions for further development. And we will do all of the above in Python. The data was downloaded from Kaggle.

It is pretty straightforward.

Introduction to Using Python for People Analytics

Gives this table:. The department column of the dataset has many categories and we need to reduce the categories for a better modeling. The department column has the following categories:. There are employees left and employees stayed in our data. Let us get a sense of the numbers across these two classes:. We can calculate categorical means for categorical variables such as department and salary to get a more detailed sense of our data like so:. Let us visualize our data to get a much clearer picture of the data and the significant features.

Predict Employee Turnover With Python

Gives this plot: It is evident that the frequency of employee turnover depends a great deal on the department they work for. Thus, department can be a good predictor of the outcome variable. Gives this plot: The proportion of the employee turnover depends a great deal on their salary level; hence, salary level can be a good predictor in predicting the outcome. Histograms are often one of the most helpful tools we can use for numeric variables during the exploratory phrase.

Gives this plot:. There are two categorical variables department, salary in the dataset and they need to be converted to dummy variables before they can be used for modelling. The actual categorical variable needs to be removed once the dummy variables have been created.

Column names after creating dummy variables for categorical variables:. The Recursive Feature Elimination RFE works by recursively removing variables and building a model on those variables that remain.

It uses the model accuracy to identify which variables and combination of variables contribute the most to predicting the target attribute. There are total 18 columns in X, how about select 10? Cross validation attempts to avoid overfitting while still producing a prediction for each observation dataset. We are using fold Cross-Validation to train our Random Forest model. The average accuracy remains very close to the Random Forest model accuracy; hence, we can conclude that the model generalizes well.

We construct confusion matrix to visualize predictions made by a classifier and evaluate the accuracy of a classification. When an employee left, how often does my classifier predict that correctly? Out of all the turnover cases, random forest correctly retrieved out of When a classifier predicts an employee will leave, how often does that employee actually leave?

The receiver operating characteristic ROC curve is another common tool used with binary classifiers. The dotted line represents the ROC curve of a purely random classifier; a good classifier stays as far away from that line as possible toward the top-left corner. According to our Random Forest model, the above shows the most important features which influence whether to leave the company, in ascending order. This brings us to the end of the post. Employee turnover analysis can help guide decisions, but not make them.

Use analytics carefully to avoid legal issues and mistrust from employees, and use them in conjunction with employee feedback, to make the best decisions possible. Source code that created this post can be found here.The key to success in an organisation is the ability to attract and retain top talents.

It is vital for the Human Resource HR Department to identify the factors that keep employees and those which prompt them to leave. Organisations could do more to prevent the loss of good people.

Machine Learning models can help to understand and determine how these factors relate to workforce attrition. Jupyter notebook with Python codes here. The dataset is well organised with no missing values. Are employees leaving because they are poorly paid?

This can be confirmed later at feature importance. Overtime seems to be one of the key factors to attrition, as a larger proportion of overtime employees has departed. There are only 3 departments included for this analysis. Data has to be preprocessed as machine learning models are better at reading numbers than words. Using label encoding, categorical data can be replaced with numbers. Below code is to display all categorical data. Next I split the data into ratio.

After tuning hyperparameters and the threshold, the Logistic Regression has achieved F1-score Also, if features are closely related to one another multicollinearityone of them has to be removed to prevent misleading results to linear models such as Logistic Regression.

Although tree-based models are not directed affected, they could also lead to over-fitting. Run below code to locate the highest correlated features, and drop the one with lower feature importance. However, HR seems to have done fabulously in job matching as this feature did not emerge useful.

This time, Random Forest Classifier emerged with F1-score As a result, there is a possibility that the model built might be biased towards to the majority and over-represented class. Random Forest Classifier has emerged as the final winning model with F1-score This could be the highest possible score achieved with the inherent limitations in the dataset. This could be due to a bad compensation process or causing a poor work-life balance. The next important factor seems to be personal relationships with fellow workers, where current manager and job role could be the main contributing reasons for attrition.

Finally, employee engagement is a critical satisfaction factor, and the organisation should keep employees constantly involved and motivated. Machine learning models are as good as the data you feed it, and more data would strengthen the model.
