A research paper by scientists at Hainan University proposed FSS-eq2Seq as a 2-stage strategy for gait synergy modeling in lower limb assistive devices to achieve synergic and user-adaptive trajectories that improve human-machine interactions. The new research paper, published on Jul. 3 in the journal Cyborg and Bionic Systems, indicatedSeq2Seq outperforms LSTM, RNN, and GRU in both interlimb and intralimb synergy modeling. Further, FS significantly improves Seq2Seq’s modeling performance. The concept of Read More
