WebFlink ML provides support for vectors of double values. A Vector in Flink ML can be either dense ( DenseVector) or sparse ( SparseVector ), depending on how users create them accordig to the vector’s sparsity. Each vector is initialized with a fixed size and users may get or set the double value of any 0-based index location in the vector. Web14. nov 2024 · c.sparseVector() is an S3 method for all "sparseVector"s, but automatic dispatch only happens for the first argument, so it is useful also as regular R function, see the examples.
