CSVMultiSequenceRecordReader
CSVMultiSequenceRecordReader: Used to read CSV-format time series (sequence) data where there are multiple
independent sequences in each file.
The assumption is that each sequence is separated by some delimiter - for example, a blank line between sequences, or some other line that can be detected by a regex. Note that the number of columns (i.e., number of lines in the CSV per sequence) must be the same for all sequences. It supports 3 CSVMultiSequenceRecordReader.Modes:(a) CONCAT mode: the output is a univariate (single column) sequence with the values from all lines (b) EQUAL_LENGTH: Require that all lines have the exact same number of tokens (c) PAD: For any shorter lines (fewer tokens), a user-specified padding Writable value will be used to make them the same length as the other sequences Example: Input data: |
