Ted Dunning commented on MAHOUT-1135:
-------------------------------------
Is there any value to the super class? In particular, forcing WeightedVector
into this mold seems to have an object creation cost.
Isn't the real value here the realization that MatrixSlice could have been a
vector all along?
> Unify decorated vectors in DecoratedVector<T>

> Key: MAHOUT-1135
> URL: https://issues.apache.org/jira/browse/MAHOUT-1135
> Project: Mahout
> Issue Type: Wish
> Components: Math
> Affects Versions: 1.0
> Reporter: Dan Filimon
> Priority: Minor
> Labels: improvement, vector
>
> I'm finding the current Vector classes in Mahout a bit confusing.
> The vector implementation are just fine, I'm talking more about the decorated
> vectors:
> WeightedVector
> MatrixSlice
> NamedVector
> I propose using a single DecoratedVector<T> type that can easily be extended.
> For example, right now MatrixSlice doesn't even implement the Vector
> interface.
> So,
> WeightedVector -> DecoratedVector<Pair<Integer, Double>>
> MatrixSlice -> DecoratedVector<Integer>
> NamedVector -> DecoratedVector<String>
> We could even keep the names (maybe changing MatrixSlice to something like
> IndexedVector though?) by extending DecoratedVector<T>.
> I'd be willing to fix this if people think it's a good idea.
> What about it? :)
