06 Jun 2013 Fast K-means clustering Fast mex K-means clustering algorithm with possibility of K-mean++ initialization. Author: Sebastien PARIS

Kota,

I confirmed the bahaviour. In another way, why ask more clusters than the cardinality of your data ?

Kota,

Thank you for reporting.... I will check this
28 May 2013 Scenes/Objects classification toolbox Scenes recognition toolbox for vision systems Author: Sebastien PARIS

Zbingos... How big is your dataset ?. How many images?. In my current version now everything is passing trough a file so requiering low memory for a just a slight slowdown ..

Zbingos,

The version of the toolbox is old compare to my current one. I have to update it I know ... but have to spend of time to check compatibility, debugging etc... In the new version you have

i) New local features: HLBP/HLTP/DV, etc..
ii) New encoders/pooler: LCC, Local sparse coding, Fisher vector, lp-norm pooling
iii) cascade up to 3 layers
iv) cross-training capacity

Everything have been redesign completly compared to the current one...

Actually I don't have time to do this update, hope within 1 month... Please understand.
To asnwer to your question:
1) what are the 1 et 2 choices ?

2) norm is a vector (1 x 3). norm(1) for the all concatenated vector, norm(2), for all current level of the pyramid, norm(3) for each individual ROI where you are pooling

3) Did you extract first the corresponding descriptor ?

Unfortunatly with two branches ... The table lookup version is much better.. If you want to do it with my toolbox, I will include your work :)

Thank you for checking. The reason is that there are cases where the cardinality of the data is unknown before applying clustering. Well, I can first check the cardinality of the data and then use k <= cardinality but I just thought it would be great if your code could handle that situation.

My input data X is a set of one dimensional scalar and the values are taken from a finite discrete set S, e.g., S = {1,2,3,4,5}. When I run yael_kmeans with K>|S|, it looks like yael_kmeans goes into an infinite loop. Do you have any idea on how to fix it?
