Uses of BaseRecordReader in org.datavec.api.records.reader.impl.csv

Subclasses of BaseRecordReader in org.datavec.api.records.reader.impl.csv

Modifier and Type	Class and Description
class	CSVLineSequenceRecordReader CSVLineSequenceRecordReader: Used for loading univariance (single valued) sequences from a CSV, where each line in a CSV represents an independent sequence, and each sequence has exactly 1 value per time step. For example, a CSV file with content:
class	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:
class	CSVNLinesSequenceRecordReader A CSV Sequence record reader where: (a) all time series are in a single file (b) each time series is of the same length (specified in constructor) (c) no delimiter is used between time series For example, with nLinesPerSequence=10, lines 0 to 9 are the first time series, 10 to 19 are the second, and so on.
class	CSVRecordReader Simple csv record reader.
class	CSVRegexRecordReader A CSVRecordReader that can split each column into additional columns using regexs.
class	CSVSequenceRecordReader CSV Sequence Record Reader This reader is intended to read sequences of data in CSV format, where each sequence is defined in its own file (and there are multiple files) Each line in the file represents one time step
class	CSVVariableSlidingWindowRecordReader A sliding window of variable size across an entire CSV.

Uses of BaseRecordReader in org.datavec.api.records.reader.impl.jackson

Subclasses of BaseRecordReader in org.datavec.api.records.reader.impl.jackson

Modifier and Type	Class and Description
class	JacksonLineRecordReader JacksonLineRecordReader will read a single file line-by-line when .next() is called.
class	JacksonLineSequenceRecordReader The sequence record reader version of JacksonLineRecordReader. Assumptions here: 1.
class	JacksonRecordReader RecordReader using Jackson. Design for this record reader: - Support for JSON, XML and YAML: one record per file only, via Jackson ObjectMapper: - JSON: new ObjectMapper(new JsonFactory()) - YAML: new ObjectMapper(new YAMLFactory()) (requires jackson-dataformat-yaml dependency) - XML: new ObjectMapper(new XmlFactory()) (requires jackson-dataformat-xml dependency) - User provides a list of fields to load, using FieldSelection.
