Web因为在代码里，CRF 通过函数crf_log_likelihood 直接计算得到整个句子级别的 loss，而不是像上面一样，用交叉熵在每个字上计算 loss，所以这种基于 mask 的方法就没法用了. 但是从实验效果来看，虽然去掉了 CRF，但是加入 WOL 之后的方法的 F1Score 还是要大一些。 WebJun 3, 2024 · A [batch_size, max_seq_len, num_tags] tensor of unary potentials to use as input to the CRF layer. tag_indices: A [batch_size, max_seq_len] matrix of tag indices for which we compute the log-likelihood. sequence_lengths: A [batch_size] vector of true sequence lengths. transition_params: A [num_tags, num_tags] transition matrix, if available.

Webedc_metadata. edc-metadata puts a "metadata" layer on top of your data collection forms, namely CRFs and Requisitions. The "metadata" is used on the data entry dashboard (see also edc_dashboard).The metadata may be queried directly by a data manager to review the completion status of CRF and Requisition forms. WebJul 1, 2024 · The CRF model Conditional random field (CRF) is a statistical model well suited for handling NER problems, because it takes context into account. In other words, when a CRF model makes a prediction, it factors in the impact of neighbouring samples by modelling the prediction as a graphical model.
