This is a version of ML-Plan that tries to cope with medium sized data in the sense of big files. That is, the data is still enough to be organized in a single file such that no streaming is required. The data is, however, in general too large to be entirely loaded into memory. We use simple sampling to create a relatively small subset of the data, then run info gain, and then ML-Plan with learning curve prediction.
