StreamDef(field = NULL, shape = NULL, is_sparse = FALSE,
  transforms = NULL, context = NULL, scp = NULL, mlf = NULL,
  broadcast = NULL, defines_mb_size = FALSE)

`field`	string defining the name of the stream
`shape`	- list of ints representing tensor shape integer defining the dimensions of the stream
`is_sparse`	logical for whether the data is sparse (FALSE by default)
`transforms`	list of transforms to be applied to the Deserializer
`context`	vector of length two defining whther reading in HTK data, (only supported by 'HTKFeatureDeserializer')
`scp`	list of 'scp' files for HTK data
`mlf`	list 'mlf' files for HTK data
`broadcast`	logical for whether the streams should be broadcast to the whole sequence
`defines_mb_size`	logical for whether this stream defines minibatch size
