Functions ¶

func FeatureClassKey ¶

func FeatureClassKey(feat string, clas string) string

Types ¶

type Class ¶

type Class = KV

type Feature ¶

type Feature = KV

type KV ¶

type KV struct {
	Label string
	Value float64
}

func (KV) IsZero ¶

func (k KV) IsZero() bool

type KVSlice ¶

type KVSlice []KV

func NewKVSlice ¶

func NewKVSlice(cap int) KVSlice

func (KVSlice) Len ¶

func (s KVSlice) Len() int

func (KVSlice) Less ¶

func (s KVSlice) Less(i, j int) bool

func (KVSlice) Swap ¶

func (s KVSlice) Swap(i, j int)

type PerceptronJSONModel ¶

type PerceptronJSONModel struct {
	Weights map[string]map[string]float64
	Classes map[string]struct{}
}

type Sentence ¶

type Sentence struct {
	Words []string
	Tags  []string
}

type Weights ¶

type Weights struct {
	// contains filtered or unexported fields
}

Each feature gets its own weight vector, so weights is a dict-of-dicts

func NewWeights ¶

func NewWeights(cap int) *Weights

NewWeights init Weights

func NewWeightsFromMap ¶

func NewWeightsFromMap(mp map[string]map[string]float64) *Weights

func (Weights) Features ¶

func (w Weights) Features() <-chan string

Features

func (Weights) GetFeatureLength ¶

func (w Weights) GetFeatureLength(feat string) int

func (Weights) GetFeatureWeights ¶

func (w Weights) GetFeatureWeights(feat string) <-chan KV

GetFeatureWeights get a feat classes weights

func (Weights) GetWeight ¶

func (w Weights) GetWeight(feat string, clas string) float64

GetWeight get class weight value

func (Weights) Map ¶

func (w Weights) Map() map[string]map[string]float64

Map convert weights to map

func (*Weights) SetWeight ¶

func (w *Weights) SetWeight(feat string, clas string, value float64)

SetWeight set a weight value for feat->clas
