Re: The explanation of input text format using LDA in Spark
hi keegan, Thanks a lot. Now I know the column represents all the words without repetition in all documents. I don't know what determine the order of the words, is there any difference when the column words with the different order? Thanks.

The explanation of input text format using LDA in Spark
Hi all, After I read the example code using LDA in Spark, I found the input text in the code is a matrix. the format of the text is as follows: 1 2 6 0 2 3 1 1 0 0 3 1 3 0 1 3 0 0 2 0 0 1 1 4 1 0 0 4 9 0 1 2 0 2 1 0 3 0 0 5 0 2 3 9 3 1 1 9 3 0 2 0 0 1 3 4 2 0 3 4 5 1 1 1 4 0 2 1 0 3 0 0 5 0 2 2 9 1 1 1 9 2 1 2 0 0 1 3 4 4 0 3 4 2 1 3 0 0 0 2 8 2 0 3 0 2 0 2 7 2 1 1 1 9 0 2 2 0 0 3 3 4 1 0 0 4 5 1 3 0 1 0 But I don't know the explanation of each line or each column. And if I have several text documents, how do I process them to use LDA in Spark? Thanks.

Re: How to implement multinomial logistic regression(softmax regression) in Spark?
Did I describe the problem not clearly? Is anyone familiar to softmax regression? Thanks.
