Re: [Databionic-ESOM-User] Problem when integrating ESOM with Matlab

[Flavius da L. G. <fl...@dc...>]

Hi Fabian and Yok,

I actualized my toolbox with missing files which you send, but the
troubles remains (see below). What can I try now?

Yok, do you succeeded in completing your work?

Thanks

Re: [Databionic-ESOM-User] Problem when integrating ESOM with Matlab

[<fa...@my...>]

Hi,

even if it doesn't look like it this is also an error due to a missing file.
our "trim" function is missing and instead one of the same name in
simulink is found and used.

I included all missing files that I know about in a *.zip file that is
linked on
    http://databionic-esom.sourceforge.net/install.html
please keep complaining until it works.

When I developed the toolbox I must have had all this code in my
matlab search p[ath without thinking about it. you guys seem to be
the first people using the matlab interface (at least the first that ever
complained).

Hi Yok Yen,

Hi Fabian,

Thanks for your support.
I still getting an error while trying to run the esom_demo.m

        if ~isnumber(t)

Error in =3D=3D> loadlrn at 56
        [data,names,defined] =3D loadlrnfast(filename);

Error in =3D=3D> esom_demo at 61
[wts, bm, umx] =3D esom_train(NOData, prefix, epochs, rows, columns, grid,
radius, learn, algorithm);

[Databionic-ESOM-User] Problem when integrating ESOM with Matlab

[Yok Y. <yo...@gm...>]

Hi,

I am trying to integrate ESOM with my matlab problem.
However, it is not successful.
Hope to seek your help in this.
Thanks in advance.

The errors that shows up when I try to run esom_demo.m are as follows:
1)
>> esom_demo
??? Undefined command/function 'tail'.

Error in ==> addfileext at 29
if ~strcmp(tail(filename,length(ext)),ext)

Error in ==> savecls at 32
filename = addfileext(filename,'.cls');

Error in ==> esom_demo at 54
savecls('demo.cls', key, cls);

2)
??? Undefined command/function 'head'.

Error in ==> loadlrnfast at 60
    tokens = strread(deblank(head(line,-1)),'%s\t');

Error in ==> loadlrn at 56
        [data,names,defined] = loadlrnfast(filename);

Error in ==> esom_train at 144
    data = loadlrn([prefix, '.lrn']);

Error in ==> esom_demo at 61
[wts, bm, umx] = esom_train(NOData, prefix, epochs, rows, columns, grid,
radius, learn, algorithm);

The average quantizatior error is the error printed for the last epoch?
I have one more problem I had performed training with one dataset and a 
umx matrix is produced.
when I load the cls file while I have open the umx the clustering is not 
successful. The bestmatches of one class are over the bestmatches of the 
other no clusters are created.
any suggestions to solve this ??
Should I try another training alogorithm? My data is the problem?
thanks,
Katerina

Re: [Databionic-ESOM-User] Font size for SOM name labels.

[Matthew K. <ema...@in...>]

Yes=21 That is a massive improvement. Thank you very much for replying so =
promptly with a fix. I can now be reassured that the Hierarchical =
Clustering (via DELTA) and SOM (via ESOM) aspects of my project are fairly =
secure and move on to K-Means...

It is worth noting that there is still some overlap - so perhaps some =
later version could adjust the positioning of labels slightly to avoid =
this. Nevertheless, I can replace the names (e.g. HD_189733) with shorter =
numbers or an ID code for my purposes, and it is definitely usable.

Matthew

Re: [Databionic-ESOM-User] Font size for SOM name labels.

[<fa...@my...>]

Matthew,

you are right, this function is not very well designed, yet. I tried a
simple fix that limits
the maximum font size to 12 (which was previously used at zoom level 6)
and also uses
a minimum font zise of 10. I will send a modified jar to your personal
email, just replace
the one in your lib folder. If you think this is better I will include
it in a future release.

Re: [Databionic-ESOM-User] Can ESOM scale to large data sets

[<fa...@my...>]

Sesan,

we have successfully used ESOM with datasets of this size and beyond. It
should in principle not make a difference
except for the training time. are you using the same normalization? an
error in preprocessing can lead to
meaningless results.

You may want to increase the map size to have a higher resolution and
not have a too 'crowded' map. Then you also
should increase the start radius proportionally.

If you can draw a small representative sample from your large dataset
you could try to cluster the sample, check
for meaningful results, and then project the full dataset onto the map
in classification mode. This will be much faster
than training with the full set. Of course this is problematic if the
sample is not representative and the full dataset
may contain additional clusters.

hope this helps

[Databionic-ESOM-User] Can ESOM scale to large data sets

[Sesan A. <ses...@ya...>]

Hi
  I am using Databionics ESOM (along with other software) for my reseach. The data set that am working on can be really large (up to 10,000 rows of data in about 5 colums in an Excel spreadsheet.
   
  When i tried ESOM using a smaller data set (about 600) i was able to get some meaningful results. However with a data set of 2000 data elements i couldn't get any meaningful clusters (other none graphical software did). 
   
  I really like the ESOM software because its comprehensive and flexible, however, it just won't give any meaning results. I varied the epochs (up to 500), varied the map size etc, but still won't work or can't visualize the clusters if they really are there!!!
   
  How can i solve this problem or is it that the ESOM can't scale to large values.
   
  Thanks

[Databionic-ESOM-User] Font size for SOM name labels.

[Matthew K. <ema...@in...>]

I have been using Databionics ESOM for my dissertation (amongst other =

since the map shrinks along with the font) appears extremely large (size =

run over each other and become illegible. It is exceedingly frustrating =
because were the font at, say, 8 or 10, at 10x zoom, then the application =

Re: [Databionic-ESOM-User] eSOM Kfold, training error??

[<fa...@my...>]

Katerina,

ESOM is an unsupervised method, so I think k-fold training to optimize
certain parameters makes only very limited sense. In supervised problems
all you care about is the accuracy (or a similar measure). Crucial
parameters of a classifier (like C for SVM) can be optimized using
k-fold crossvalidation to avoid overfitting. For unsupervised methods
like ESOM or clustering there are several alternative measures that you
might want to optimize. But if you would want to optimize map size to
achieve a low quantization error you will most likely get smaller errors
as the map grows, because a larger parameter space can better represent
your data. A small quantization error does not necessarily mean you have
the best map (e.g. the best visualization, the best untangling of
clusters, ...).

As for the speed there are people working on speeding up ESOM training
and I hope these methods will be incorporated in a future version.

Hi Mario,
thank you, but what about kfold????
Is there a command I can use to perform kfold for the tuning of 
parameters????

another problem I face is that the overhead is really high for training 
datasets around 20000 records any suggestions for this problem?

Re: [Databionic-ESOM-User] eSOM Kfold, training error??

[Mario N. <noe...@Ma...>]

Hi Katerina,

the only training error which is implemented yet, is the average
quantization error.

If you change the entry for log4j.category.databionics in the
etc/esom.conf file from INFO to DEBUG the quantization error will be
logged after every epoch of training.

The parameters which can be tuned are (in my opinion) the size of the
map, the values for radius and learning rate, the neighborhood function,
the number of epochs and the initialization method.

Re: [Databionic-ESOM-User] Weight errors while running ESOM!

[<fa...@my...>]

Hi Preeti,

it is possible that your problem is related to missing values or
calculation errors from division by zero or something
like that. this is hard to tell without seeing the data. can you send me
a sample to my personal email where the
problem occurs?

for best result you should be using the online algorithm, see
http://www.mathematik.uni-marburg.de/~databionics/de//downloads/papers/noecker06fast.pdf

the parameter selection is in general not all that crucial. the default
settings will most likely work well for many problems.

increasing the number of training epochs mainly means smoothing the
training process, since the radius and learning
rate are always cooled from start to end.

if you have a large dataset you might want to make the map bigger to
increase the resolution of you views into the high
dimensional data space.

pca weight initialization will give you more reproducible map layouts
but is very expensive. random works too and is faster.

more important than the learning rate is the radius and more important
than start values are end values. a larger end
radius will give you a smoother mapping, while a smaller end radius will
give you more details.

bye
fabian

[Databionic-ESOM-User] Weight errors while running ESOM!

[Preeti S. <ps...@ya...>]

Hello! everyone,
 
I am new to ESOM and have been using it to classify a huge database. First of all, I have noticed that many times when I train the dataset, I save the weights (*.wts) and the best matching (*.bm) along the way. After the training is complete, I get a weird visualization, where most of the map is blue and white dots (best matching units) in between here and there. When I go into the weight file, I can see that it has some weird characters instead of numbers. I dont know what I am doing wrong? I have tried several times and I keep getting the same visualization and weight files most of the time. One out of 10 trainings gives me the correct visualization. Can anyone help me in finding out where the mistake lies? second of all, how do you know what parameters are the optimal ones for running your dataset? For example, how many epochs I should run it for? Which training algorithm should I use? which weight initilization method is the best? start value for learning rate? etc. 
 
Looking forward to hearing from some of you!
 
Best Regards,
Preeti

This is surely possible. Any height matrix that you can create
with the ESOM tools can be saved as a *.umx file. The file
extension is a little misleading, but in the beginning there
was only the U-Matrix. With the command line tools you could
save the P-Matrix with
