WebFeb 20, 2024 · bilstm-crf 是一种结合了双向长短时记忆网络（bilstm）和条件随机场（crf）的序列标注模型，常用于自然语言处理中的命名实体识别和分词任务。 BiLSTM 是一种递归神经网络，它能够通过前向和后向两个方向的信息流动，捕捉到输入序列中的上下文信 … WebThe Keras-CRF-Layer module implements a linear-chain CRF layer for learning to predict tag sequences. This variant of the CRF is factored into unary potentials for every element in the sequence and binary potentials for every transition between output tags. Usage Below is an example of the API, which learns a CRF for some random data.
