Weka For Mac



There are two versions of Weka: Weka 3.8 is the latest stable versionand Weka 3.9 is the development version. New releases of these two versionsare normally made once or twice a year. For the bleeding edge, it isalso possible to download nightly snapshots of these two versions.

The stable version receives only bug fixes and feature upgrades thatdo not break compatibility with its earlier releases, while thedevelopment version may receive new features that break compatibilitywith its earlier releases.
