A RowTransformer
which transform each selected columns
to a size(1) Tensor
.
The keys of output Table
are fieldNames
of selected columns
.
field names of selected columns
A RowTransformer
which contains both atomic
schemas and numeric
schemas.
A RowTransformer
which contains both atomic
schemas and numeric
schemas.
field names of selected columns
Map<schemaKey
, fieldNames of selected columns
> of numeric fields
A RowTransformer
which concat values of selected columns
to one Tensor
.
A RowTransformer
which concat values of selected columns
to one Tensor
.
It means you will get a Table
with keys of numericFields
.
Values of Table
are Tensor
s concatenated by selected columns
of the keys.
Map<schemaKey
, fieldNames of selected columns
> of numeric fields
A RowTransformer
which concat values of all columns
to one Tensor
.
A RowTransformer
which concat values of all columns
to one Tensor
.
It means you will get a Table with single key-value pair after transformation.
The unique key is schemaKey
. The unique value is a size(length of Row) Tensor.
key of the schema, default value is "all"
