Kotlin for Data Science - Getting Started

Data science is a field that involves extracting valuable insights from data. While Python and R are commonly used in data science, Kotlin can also be a great choice. In this guide, we'll show you how to get started with Kotlin for data science.

Setting Up Your Environment

Before you start, make sure you have the following tools and libraries installed:

  • Kotlin
  • An integrated development environment (IDE) like IntelliJ IDEA
  • Kotlin libraries for data science (e.g., Kotlin-Num, Kotlin-Math, Apache Spark with Kotlin bindings)

Step 1: Exploratory Data Analysis (EDA)

EDA is the first step in data science. Load your dataset and perform basic data analysis to understand its structure and characteristics. You can use libraries like Kotlin-Num or Kotlin-Math to help with data manipulation and visualization.

Step 2: Data Preprocessing

Clean and preprocess your data. This includes handling missing values, data scaling, and feature engineering. Kotlin provides tools for data preprocessing, and you can also use Apache Spark for distributed data processing.

Step 3: Model Building

Choose the appropriate machine learning or statistical models for your task. You can implement these models in Kotlin using libraries like Kotlin for Apache Spark or implement your custom models using Kotlin's native capabilities.

Step 4: Model Training

Train your machine learning models on your preprocessed data. Kotlin libraries for data science provide the necessary tools for model training and evaluation.

Step 5: Model Evaluation

Evaluate the performance of your models using metrics like accuracy, precision, recall, or custom evaluation criteria. Visualize the results to gain insights from the model's behavior.

Step 6: Deployment

If your model performs well, you can deploy it in a production environment. This can be done using Kotlin in server-side applications or by creating APIs to serve predictions.

Additional Resources

Learning Kotlin for data science is an ongoing process. You can find resources like books, online courses, and documentation to deepen your knowledge and skills in this field.


Kotlin is a versatile language that can be used for data science alongside Python and R. This guide provides a high-level overview of how to get started with Kotlin for data science. Depending on your project's complexity, you may need to explore specific libraries and frameworks to suit your needs.

Happy data science with Kotlin!
