document (sparse) data format #4

Open 3bst0r opened 8 years ago

3bst0r commented 8 years ago

Please document the data format that the tsne model wants with type 'sparse'. I tried a nested array like [[i_11,...i_1j],...[i_n1,...i_nk]] where i_rs are the indices of the set values but that did not work.

for anyone wondering, it seems to be [ [i1, j1], ... , [in, jn] ] where i,j are the indices of the non-zero values.
