Web17 jan. 2024 · Bidirectional LSTMs are supported in Keras via the Bidirectional layer wrapper. This wrapper takes a recurrent layer (e.g. the first LSTM layer) as an argument. It also allows you to specify the merge mode, that is how the forward and backward outputs should be combined before being passed on to the next layer. The options are: Web10 apr. 2024 · crf（条件随机场）是一种用于序列标注问题的生成模型，它可以通过使用预定义的标签集合为序列中的每个元素预测标签。 因此，bert-bilstm-crf模型是一种通过使用bert来捕获语言语法和语义信息，并使用bilstm和crf来处理序列标注问题的强大模型。
