What's New in RapidMiner Server 7.5?
This page describes the new features of RapidMiner Server 7.5 as well as its enhancements.
More improvements in performance
This release is again focused on performance, but from another point of view: memory. RapidMiner 7.5 features a new data core that manages data sets in a much more efficient way. Some of the benefits of the new data core are:
- Lower memory footprint through more compact data representations. Better data management allows larger datasets to be processed.
- Sparse datasets are detected and special data structures handle them for an increase in efficiency.
- New data management modes (speed-optimized, auto, memory-optimized) allow you to select the optimal representation for your data.
- The data core now keeps data in a columnar format, which significantly speeds up many data preparation tasks that modify or create new attributes.
