How to initialize weights by using LSH ？

I don't understand how to initialize weights by LSH. I have two points, but i don't know which is true.
The one is using LSH on the dataset before the training and we can get the mapped data. Then we can use the data pair (data, mapped data) to fine tuning our Net.
The other one is that we can get the mapping matrix by LSH and use this as the weights directly.

I have understood.
