Sorry, I forgot to mention the following: all I wrote is only valid as long
as your number of samples is smaller than the number of different words. If
the number of samples exceeds the total number of different words, you
should better use the explicit matrix representation and use some kernel
(e.g. linear) on this matrix.

Best regards,
