Hi all,
while implementing Locality Preserving Projections ,
at one point i have to perform X L X.transpose()
these matrices are large (32256 x 32256) so i get "out of memory" error.
I assume, as the dataset gets larger one would come across this problem ,
how would
one go about solving this ? Is
Hope this helps

2. very low learning curve.
pyTables seems to be more suitable but , i somehow found the learning curve
too steep . Also pyTables needs lot of in
