Tie the word embedding and softmax weights
Webb11 apr. 2024 · It takes the topic distribution θ, the topic-word weight matrix W d e c, and the word embedding x t e of the input sequence as input. The outputs of the multi-level topic-aware mechanism are the word-level and corpus-level topic representation. The multi-level topic-aware mechanism will be described in detailed below. Webb2.

Webbterm score is then weighted using a gating mech-anism (topmost box nodes in Fig.1) that exam-ines properties of the q-term to assess its impor-tance for ranking (e.g., common words are less im-portant). The sum of the weighted q-term scores is the relevance score of the document. This ig-nores entirely the contexts where the terms occur,
