类 MinHashLSH

java.lang.Object

org.apache.flink.ml.feature.lsh.MinHashLSH

所有已实现的接口:

Serializable, org.apache.flink.ml.api.Estimator<MinHashLSH,MinHashLSHModel>, org.apache.flink.ml.api.Stage<MinHashLSH>, org.apache.flink.ml.common.param.HasInputCol<MinHashLSH>, org.apache.flink.ml.common.param.HasOutputCol<MinHashLSH>, org.apache.flink.ml.common.param.HasSeed<MinHashLSH>, LSHModelParams<MinHashLSH>, LSHParams<MinHashLSH>, MinHashLSHParams<MinHashLSH>, org.apache.flink.ml.param.WithParams<MinHashLSH>

public class MinHashLSH
extends Object
implements MinHashLSHParams<MinHashLSH>

An Estimator that implements the MinHash LSH algorithm, which supports LSH for Jaccard distance.

The input could be dense or sparse vectors. Each input vector must have at least one non-zero index and all non-zero values are treated as binary "1" values. The sizes of input vectors should be same and not larger than a predefined prime (i.e., 2038074743).
