What does the is_sparse mean in StreamDef?

I'm new to CNTK and quite confused about the is_sparse argument in StreamDef. Does it mean the input file has to be in some specific format?

Solution

Yes, it means that the corresponding field in the CTF file is expected to be formatted as zero or more feature_index:feature_value pairs.
