Hello,
No I don't have it and I don't plan to implement it since UPGrowth was shown to be faster, HUI-Miner was shown to be faster than UPGrowth and FHM was shown to be faster than HUI-Miner.
Therefore, I have no interest in implementing IHUP.
You can get the source code of Two-Phase, HUI-Miner and FHM in the
SPMF data mining library. On the download page you can also get the datasets.
Best,
