init(column:)

Creates a new column of machine learning sequences from a given column whose elements can be converted to sequences.

Declaration

init<T>(column: MLDataColumn<T>) where T : MLDataValueConvertible

Parameters

column:
An Mldatacolumn of elements convertible to Sequencetype.

Discussion

Use this initializer to create a column of sequences from another column. Start by creating a column that is convertible to a column of sequences.

let intSequenceString = "[1, 2, 3]"
let intSequenceString2 = "[4, 5, 6]"
let stringsColumn = MLDataColumn([intSequenceString, intSequenceString2])

print(stringsColumn) // Prints "[1, 2, 3]", "[4, 5, 6]"]

Then use init(column:) to convert the column to a column of sequences.

let sequenceColumn = MLDataColumn<MLDataValue.SequenceType>(column: stringsColumn)
print(sequenceColumn) // Prints [[DataValue(1), DataValue(2), DataValue(3)],
                      // [DataValue(4), DataValue(5), DataValue(6)]]
