Ok. In this case I will use an Array instead.

I agree with Till, the data types are different here so you need a custom
string vector.
The Vector abstraction in FlinkML is designed with numerical vectors in
mind.

Hi Hilmi,
I think in your case it makes sense to define a custom vector of strings.
The easiest implementation could be an Array[String] or List[String].
The reason why it does not make so much sense to make Vector and
DenseVector
generic is that these types are algebraic data types. How would you define
algebraic operations such as scalar product, outer product, multiplication,
etc. on a vector of strings? Then you would have to provide different
implementations for the different type parameters.
Cheers,
Till

Hi,
how I explained it in a previous E-Mail, I need a LabeledVector where the
label is also a vector. After we discussed this issue, I created a new
class named LabeledSequenceVector with the labels as a Vector. In my use
case, I want to train a POS-Tagger system, so the "vector" is a vector of
strings and the "labels" is also a vector of strings. If I use the Flink
Vector/DenseVector implementation then the vector does only have double
values but I need String values.
Best Regards,
Hilmi

Hi Hilmi,
In NLP, which types are used for vector values? I think we can cover
typical case using double values.

the Vector and DenseVector implementations of Flink ML only allow

values. But there are cases where the values are not Doubles, e.g. in
NLP.
Does it make sense to make the implementations generic, i.e. Vector[T]
and
DenseVector[T]?
