Top 8 Java Data Science Projects

  • GitHub repo OpenRefine

    OpenRefine is a free, open source power tool for working with messy data and improving it

    Project mention: Data mapping process | reddit.com/r/dataengineering | 2021-11-05

    In terms of open source - is OpenRefine what you are after?

  • GitHub repo Smile

    Statistical Machine Intelligence & Learning Engine

    Project mention: What libraries do you use for machine learning and data visualizing in scala? | reddit.com/r/scala | 2021-11-27

    I use smile https://github.com/haifengl/smile with ammonite and it feels pretty easy/good to work with. Of course for pure looking at data, and exploration, you're not going to beat python.

  • Scout APM

    Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

  • GitHub repo airbyte

    Airbyte is an open-source EL(T) platform that helps you replicate your data in your warehouses, lakes and databases.

    Project mention: How to improve ETL tech stack for robust API calls, historization, orchestration and versioning? | reddit.com/r/dataengineering | 2021-12-01

    Shout out airbyte.io - decent flexibility, self-hosting on Kubernetes, and a commitment to no premium connectors.

  • GitHub repo Trino

    Official repository of Trino, the distributed SQL query engine for big data, formerly known as PrestoSQL (https://trino.io)

    Project mention: Learn SQL | news.ycombinator.com | 2021-08-03

    You might find https://trino.io/ interesting. It allows you to bolt on a MPP SQL execution engine on top of any data source including pre-built connectors for Druid and Kafka.

    It's all ANSI SQL and the best part is you can combine data from heterogenous sources. e.g. You can join data between a topic in Kafka and a table in Druid or even between Kafka, S3 and your RDBMS.

    Disclaimer: I'm a maintainer of the project.

  • GitHub repo Tablesaw

    Java dataframe and visualization library

    Project mention: Does Java has similar project like this one in C#? (ml, data) | reddit.com/r/java | 2021-05-23

    For data frames, tablesaw or anything with apache arrow interop would be a good way to go: https://github.com/jtablesaw/tablesaw

  • GitHub repo DatumBox

    Datumbox is an open-source Machine Learning framework written in Java which allows the rapid development of Machine Learning and Statistical applications.

  • GitHub repo zingg

    Scalable data mastering, deduplication and entity resolution.

    Project mention: GitHub Java Projects to Contribute | reddit.com/r/opensource | 2021-11-17
