[Numpy-discussion] SParse feature vector generation

[Dhruvkaran Mehta]

Hi numpy users,

*Is there a convenient way in numpy to go from "string" features like:*

"uc_berkeley", "google", 1
"stanford", "intel", 1
.
.
.
"uiuc", "texas_instruments", 0

*to a numpy matrix like:*

 "uc_berkeley", "stanford", ..., "uiuc", "google", "intel",
"texas_instruments", "bool"
          1                0         ...     0           1           0
           0                       1
          0                1         ...     0           0           1
           0                       1
          :
          0                0         ...     1           0           0
           1                       0

I really appreciate you taking the time to help!
Thanks!
