Dictionary Vectorizer for Go

MapToVec

Convert a Map with string keys to a float64 array. Numeric, boolean, and nil values are converted directly to float64. For other types, each new value encountered is given an index unique for its key.

A Vectorizer can be used to convert maps with a uniform set of keys, whose values are all comparable.

v := maptovec.NewVectorizer()

v.MapToVec(maptovec.Map{
	"a": 25,
	"b": float32(2.5),
	"c": float64(2.5),
	"d": true,
	"e": false,
	"f": "25",
	"g": nil,
}) // returns [25 2.5 2.5 1 0 1 0]

v.MapToVec(maptovec.Map{
	"a": 75,
	"b": float32(7.5),
	"c": float64(7.5),
	"d": true,
	"e": false,
	"f": "26",
	"g": struct{a string}{
		a: "abc",
	},
}) // returns [75 7.5 7.5 1 0 2 2]
