For convenience prepare proper directory structure, unpack and place files as follows:



E:\apl\lvq\source.zip contents



E:\apl\lvq\results\ (empty)



E:\apl\lvq\Data\*.txt example



E:\apl\lvq\lvq.exe



E:\apl\spectrum\results\signal_spectra_and_cepstra.spk (for 2.7 version) or .spc (for current version)

===========================================================

Version 6.1., news:

1. The procedure InitRead from the module dataProcessor was corrected - the "closeFile(initFile)" instruction was mooved into the conditional instruction "if fileExists(InitDir)". The bug caused the I/O error when the init file was'nt  present.
2. The hibernating procedure was actualised. The new one is: function SetSuspendState(Hibernate, ForceCritical, DisableWakeEvent: Boolean): Boolean;
3. A bug causing RCE when cathegory 4 processing was turned on is removed.
4. Version Delphi 12. Plots color frames encircled checkboxes switching the plots were added (procedure allCheckRectangle(form:Tform);)

Note. In the windows 10 or higher enwironment launch the Delphi 2005 as admin  to prevent its hanging up.


Version 6.0.0., news:
1. transfer of extended info about output and standardize check boxes states and state of the 0-component of spectrum analyses results and boundle analyses choice was implemented
2. printing above information to report was implemented
3. directory management edits corrected

Version 5.2., news:
1. Command "Repaint last plots" improved (important for version D11.3, because - for unknown reasons - drawing control plots does not work properly)
2. Command "SuspendOrHibernate" improved (but still does not work in version D11.3)

Version 5.1., news:
1. Distribution procedures in D11 corrected
2. Interface improvements
3. Code improvements

Version 5.0., news:
Distribution processing procedures corrected

Version 4.1.1., news:
Note. The distribution processing procedures need same attention yet...

1. Standardising function corrected

2. Control plots corrected

3. Interface improved



Version 4.1., news:

1. additional command "Repaint plots" was added

2. Program stability was strenghten

3. Monitoring of programm performance was improved

4. A bug pertaining data reading break-point was removed

5. The table 1 - 0-th row added





Version 4.0., news:

1. Some bugs in data acquisition interface was removed and improvements to it were done. 

2. Preprocessing now possible also in next sessions: Now some preprocessing procedures (i.e. standardising an|or time constant contribution removing) 

   can be turned on or off without necessity of repeating of input data loading. Original data are gathered in RAM and wait intakt for the preprocessing.

3. The txt data are now treated exactly in the same way as the spc data.

4. Now you can process events features streams of vectors of any length from 2, to 1024 components and take into account any subsets of these vectors components. 

5. You can also establish the best such subset applying incorporated the CART method (this was possible from the very 1. version).

6. Moreover you can obtain distributions of all quantisation parameters (i.e. of the information radius, distortion and recognition error)

   values over cathegories values as the function of number of groups



Version 3.1., news:

1. Data acquisition improved



Version 3.2., news:

1. One bug removed (could cause "Range checking error" while data acquisition)

2. Interface improved





Version 3, news:

1. This version works on real data values. It reads spectra data results obtained from the current program, the "Spectrum."

2. Version 3 generates different output (code book), which can not be read by the current version of encoder, i.e. by the "VQC" program

3. This version accepts 4 cathegories data vectors (see the .txt data example)



Version 2.7, news:

1. RAM allocation monitoring added

2. Interface small corrections done



Version 2.6, news:

1. Tree - information about FFT windows width added



Version 2.5.c, news:

1. Tree - information about cepstrum liftering treshold was added 

2. Help - information about the *.spk data format was supplemented (0-th record)

3. Description - information as above was supplemented and fig. "Schemat 3" was updated





Version 2.5.b, news:

1. Set constructor improved (is more resistant to editing errors now) and adequate changes in procedures InitDefault and Init[Write,Read] done

2. SaveTree, added information about wave file directory

3. Help - corrected description of the 0-th record of the *.spk data





Version 2.5.a, news:

1. Monitor, "Cardinals of final tree leaves", overlay graphs condition pertaining this graphs added





Version 2.5, news:

1. New input data format was added, namely one-stream text data

2. A lot of improvements
