Golang problem_add_train_inst Examples

Example #1

File: problem.go Project: sridif/gosvm

func (problem *Problem) Add(trainInst TrainingInstance) {
	features := sortedFeatureVector(trainInst.Features)

	nodes := C.nodes_new(C.size_t(len(features)))

	for idx, val := range features {
		C.nodes_put(nodes, C.size_t(idx), C.int(val.Index), C.double(val.Value))
	}

	C.problem_add_train_inst(problem.problem, nodes, C.double(trainInst.Label))
}

Example #2
