Class GetEmbeddingsMeanRoute

java.lang.Object

de.julielab.ml.embeddings.server.GetEmbeddingsMeanRoute

All Implemented Interfaces:

spark.Route

public class GetEmbeddingsMeanRoute
extends Object
implements spark.Route

Encodes a singe vector representing the mean of the requested word embeddings. The response indicates which word vectors were found and which one are out of vocabulary. The response format is a byte stream in the following format:

       [4 bytes]          [num words bytes]                [rest]
             
                          for each input word,
   embedding dimensions   1 byte is allocated         the byte-encoded
   (length of the         with 0 or 1 to indicate     mean vector
   embedding vectors)     that the respective          
                          word was (not) in
                          the vocabulary
 

Where the embedding vector encoding follows the format described in EmbeddingServerUtils.convertVectorToByteArray(double[]).
