When it fits — and when it doesn’t

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for new users

   The library's comprehensive nature and the need to understand both statistical concepts and Java programming can be overwhelming.

2. 02

   Limited documentation and examples

   While Rapaio is open-source, it lacks extensive tutorials or example projects that could help users quickly get up to speed with its features.

3. 03

   Narrow focus on Java ecosystem

   As a Java library, Rapaio does not support other programming languages directly, which can be a limitation for teams that prefer or require multi-language support.

4. 04

   Smaller community and slower issue resolution

   The relatively smaller user base compared to more popular libraries means less community-driven support and potentially slower response times for bug fixes and feature requests.
