Tue, 27 Jan 2009 14:52:28 +0000 | mas01mc | Fixed upper-limit (T) boundary error in MultiProbe::generatePerturbationSets(x, T). Setting this too high spins algorithm1 into infinite heap allocations without possiblity of terminating. This is now silently capped at --lsh_k * 2; the algorithm halts up to this threshold. multiprobeLSH |
Tue, 27 Jan 2009 03:49:19 +0000 | mas01mc | Working version of multiprobe LSH. Passes tests. But needs testing vis-a-vis TP improvement. In the process, found a bug in hash function projections on rare occasions admitting negative values. This only shows for large datasets and was fatal for multiprobe. multiprobeLSH |
