age author description
Tue, 03 Feb 2009 02:04:06 +0000 mas01mc Added warning about deprecated LSH_N_POINT_BITS coding. Only affects indexes built prior to rev 820 multiprobeLSH
Mon, 02 Feb 2009 17:41:02 +0000 mas01mc DELETED LSH_N_POINT_BITS coding. Tracks and points are now identified with a binary search, std::lower_bound(), on *adb->track_offsets return from LSH retrieval. multiprobeLSH
Fri, 30 Jan 2009 19:44:51 +0000 mas01mc Completed audiodb_datum_qpointers_partial(), fixed bug that was scribbling over pre-computed l2norms when points arrived in original less<PointPair> order, switched to greater<PointPair> order and all is fixed. multiprobeLSH
Fri, 30 Jan 2009 14:58:35 +0000 mas01mc Fixed a problem with inserting into exact_evaluation_queue, duplicate pairs were being inserted when querying multiple hashtables. That is now fixed by adding a unique constraint using set<PointPair> inserts and testing. This should speed things up quite a bit (like, 10-fold with default num tables). multiprobeLSH
Thu, 29 Jan 2009 13:44:47 +0000 mas01mc Added audiodb_datum_qpointers_partial() to make exact evaluation of LSH results more efficient. This routine calculates partial sums only for those vectors needed. multiprobeLSH
Wed, 28 Jan 2009 18:55:46 +0000 mas01mc Added more debugging information: report numPairs returned from LSH bucket retrieval (pre-distance computation), entry/exit from audiodb_query_spec_qpointers(...) multiprobeLSH
Fri, 23 Jan 2009 21:44:32 +0000 mas01mc Added hook for dumping LSH INDEX tables on load via compile-time switch: -DLSH_DUMP_CORE_TABLES
Thu, 15 Jan 2009 13:57:33 +0000 mas01cr Code rearrangements to tease apart library code from C++ audioDB code.
