当您说三个单词嵌入"时，我看到三个嵌入层，例如:

When you say "three word embeddings", I see three Embedding layers, such as:

input1 = Input((sentenceLength,))
input2 = Input((sentenceLength,))
input3 = Input((sentenceLength,))

emb1 = Embedding(...options...)(input1)
emb2 = Embedding(...options...)(input2)
emb3 = Embedding(...options...)(input3)

您可以使用简单的Add()层对这三个层求和:

You can use a simple Add() layer to sum the three:

summed = Add()([emb1,emb2,emb3])

然后您继续建模...

Then you continue your modeling...

#after creating the rest of the layers and getting the desired output:
model = Model([input1,input2,input3],output)

如果您不使用嵌入层，但是要输入三个向量:

If you're not using embedding layers, but you're inputting three vectors:

input1 = Input((4,)) #or perhaps (sentenceLength,4)
input2 = Input((4,))
input3 = Input((4,))

added = Add()([input1,input2,input3])

其余的都一样.

如果这不是您的问题，请提供三个单词嵌入"的来源，打算如何选择它们的详细信息，等等.

If this is not your question, please give more details about where the three "word embeddings" are coming from, how you intend to select them, etc.
