Fri, 13 Feb 2009 11:01:35 +0000 mas01cr Improve the behaviour of the RDF example a little bit. multiprobeLSH
Fri, 13 Feb 2009 11:01:32 +0000 mas01cr Produce embryonic example of integration with runner ("sonic annotator") multiprobeLSH
Thu, 12 Feb 2009 10:44:54 +0000 mas01cr Implement error exits in the SOAP client when the return code is not SOAP_OK.
Wed, 11 Feb 2009 12:38:04 +0000 mas01cr Make the Makefile test target depend on $(LIBRARY) as well as $(EXECUTABLE).
Wed, 11 Feb 2009 12:38:03 +0000 mas01cr Implement a rudimentary API for audioDB::liszt
Wed, 11 Feb 2009 10:42:23 +0000 mas02md Add the latex sources to the AudioDB spec document
Sun, 08 Feb 2009 22:32:33 +0000 mas01mc Rework new audiodb_track_id_datum_offset() and audiodb_insert_create_datum_offset() so that all offsets are in num_vectors. Internals of data storage are left the the methods to implement. If we are going to export these methods to the API, how do we expose the cache ? It needs to be passed back to the user and back in by the user on each call for caching to be re-entrant. No (intentional) functional changes this version. multiprobeLSH
Sun, 08 Feb 2009 15:53:57 +0000 mas01mc Expanded interface to audiodb_insert_create_datum() and audiodb_track_id_datum() to include _offset versions of both. Default cache is NULL, but offset and size parameters required. multiprobeLSH
Sun, 08 Feb 2009 06:41:55 +0000 mas01mc A fix for using_query_point with query_by_key (i.e. not by file). This code path still loads the entire query file, even if using one vector. Loading of query data needs better rationalization. multiprobeLSH
Sun, 08 Feb 2009 05:06:01 +0000 mas01mc Fixed non-NULL memory initializaton error. We require NULL fields for correct free() behaviour. multiprobeLSH
Sat, 07 Feb 2009 18:01:18 +0000 mas01mc This fix plugs a minor memory leak introduced in caching file references. multiprobeLSH
Sat, 07 Feb 2009 16:59:31 +0000 mas01mc Added file caching for sparse datum reads. This required making a new type called adb_fd_cache_t and modifying the read methods audiodb_track_id_datum() and audiodb_insert_create_datum() to use the cache struct if one is provided by the user. multiprobeLSH
Sat, 07 Feb 2009 12:12:46 +0000 mas01mc Fixed time-stamp option off-by-one error in new sparse scattered I/O. This probably isn't used by anyone at the moment and time-stamping needs to be tested properly anyway. multiprobeLSH
Sat, 07 Feb 2009 01:20:05 +0000 mas01mc Optimized the query_loop_points inner loop for memcpy and I/O efficiency. Uses sparse seeks and reads to perform scattered reads across data set. Current version does not cache fid between open calls to the same trackID. multiprobeLSH
Fri, 06 Feb 2009 21:08:35 +0000 mas01mc Added back single-query point I/O behaviour from pre API-inversion. Thus only those query vectors required are loaded when using query-from-file. Tests 0006 and 0007 fail silently with this change. multiprobeLSH
Fri, 06 Feb 2009 17:08:21 +0000 mas01mc Removed obsolete dbH header pointer dereferences in audioDB.cpp. Replaced with the API adb->header type calls. The dbH calls were causing segfaults when attempting to index an empty database or during batch inserts in some rare cases.
Wed, 04 Feb 2009 13:47:02 +0000 mas01cr Use upper_bound rather than lower_bound in audiodb_index_to_track_id()
Wed, 04 Feb 2009 11:37:07 +0000 mas01cr Compile fix for previous revision
Wed, 04 Feb 2009 10:45:57 +0000 mas01mc Removed LSH_N_POINT_BITS coding for LSH index. Now uses binay search via STL lower_bound to locate tracks and positions from global pointID searching over cumulative track lengths. MERGE of branches/multiprobeLSH -r 819:821 onto trunk. This is a non backward-compatible change; WARNING generated on attempt to use INDEXING with older audioDB databases. Only INDEXES are broken, not ADB instances.
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
Sat, 31 Jan 2009 16:25:30 +0000 mas01mc Removed redundant memcpy calls from query_loop_queue(). This changed the order of some memory allocation and de-allocation calls for loaded database data. 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
