age author description
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
Wed, 28 Jan 2009 17:54:18 +0000 mas01mc Set ADB_FIXME_DEFAULT_LSH_N_POINT_BITS to 15 so we can get about 20k vectors per file in the LSH point encoding. This pain and suffering will go away soon, I promise. multiprobeLSH
Wed, 28 Jan 2009 17:18:58 +0000 mas01mc _LSH_DEBUG_ option now reports correct point counts per hashtable read. multiprobeLSH
Wed, 28 Jan 2009 16:02:17 +0000 mas01mc Fixed a bug in LSH hashtable writing to disk that doesn't always sort the t2 entries into strict weak ordering. Now it does. Lots of debugging informational code inserted. multiprobeLSH
Wed, 28 Jan 2009 05:18:14 +0000 mas01mc insert some statistics gathering for hash tables, add _LSH_DEBUG_ macro to output LSH statistics on INDEX and QUERY multiprobeLSH
