Python MatrixSketcherBase Examples

Example #1

 def __init__(self, d, ell):
     MatrixSketcherBase.__init__(self, d, ell)
     self.class_name = 'RandomProjections'
     self.rescaled_signs = [-1.0, 1.0] / sqrt(self.ell)

Example #2

 def __init__(self, d, ell):
     MatrixSketcherBase.__init__(self, d, ell)
     self.class_name = 'RowSampler'
     self.samplers = [singleItemSampler() for i in xrange(self.ell)]

Example #3

     MatrixSketcherBase.__init__(self, d, ell)
     self.class_name = 'RowSampler' 
     self.samplers = [singleItemSampler() for i in xrange(self.ell)]

Example #4
