BERT-Residual Quantum Language Model Inspired by ODE Multi-Step Method
Published 2025-01-01“…Therefore, in this paper, we propose the BERT-Residual quantum language model inspired by the multi-step method of ordinary differential equations (ODE), using the density matrix to capture the semantic high-order interaction features missing in the BERT modeling process, and obtain the sentence representation, and perform the first step Residuals. Then quantum measurement is performed on the sentence representation, and the second step of residual connection is performed with the BERT layer. …”
