Creating a hot vector (numpy)

2016-04-17 Thread Paulo da Silva
Hi all. I have seen this "trick" to create a hot vector. In [45]: x Out[45]: array([0, 1]) In [46]: y Out[46]: array([1, 1, 1, 0, 0, 1, 0, 0], dtype=uint8) In [47]: y[:,None] Out[47]: array([[1], [1], [1], [0], [0], [1], [0], [0]], dtype=uint8)
