问如何保存Accord.Net K-Means的集群结果以供重用？

EN

KMeans kmeans = ...

using (FileStream fs = new FileStream(path, FileMode.Create))
{
    new BinaryFormatter().Serialize(fs, kmeans);
}    

KMeans kmeans = null;

using (FileStream fs = new FileStream(path, FileMode.Open))
{
    kmeans = new BinaryFormatter().Deserialize(fs) as KMeans;
}    

KMeans means;
Accord.IO.Serializer.Save(means, filename);

means = Accord.IO.Serializer.Load<KMeans>(filename);

// Saving the Centroids
int[] clusterIds = kmeans.Compute(observations);
double[][] centroids = kmeans.Clusters.Centroids;

// Initializing with Centroids
kmeans = new KMeans(numOfClusters);
kmeans.Clusters.Centroids = centroids;
int[] clusterIds = kmeans.Compute(observations);
