Stability and agility: biped running over varied and unknown terrain

Yang YI,Zhi-yun LIN

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 4, Pages 283-292 doi: 10.1631/FITEE.1400284

Abstract: We tackle the problem of a biped running over varied and unknown terrain.Running is a necessary skill for a biped moving fast, but it increases the challenge of dynamic balanceTo address this issue, a new dynamic indicator called the sustainable running criterion is developed.a running-feasible set, instead of running on a periodic limit cycle gait in the traditional way.Finally, the position and velocity of the COG are driven into the running-feasible set.

Machine learning for detecting mesial temporal lobe epilepsy by structural and functional neuroimaging

Baiwan Zhou, Dongmei An, Fenglai Xiao, Running Niu, Wenbin Li, Wei Li, Xin Tong, Graham J Kemp, Dong

Frontiers of Medicine 2020, Volume 14, Issue 5, Pages 630-641 doi: 10.1007/s11684-019-0718-4

Abstract: Mesial temporal lobe epilepsy (mTLE), the most common type of focal epilepsy, is associated with functional and structural brain alterations. Machine learning (ML) techniques have been successfully used in discriminating mTLE from healthy controls. However, either functional or structural neuroimaging data are mostly used separately as input, and the opportunity to combine both has not been exploited yet. We conducted a multimodal ML study based on functional and structural neuroimaging measures. We enrolled 37 patients with left mTLE, 37 patients with right mTLE, and 74 healthy controls and trained a support vector ML model to distinguish them by using each measure and the combinations of the measures. For each single measure, we obtained a mean accuracy of 74% and 69% for discriminating left mTLE and right mTLE from controls, respectively, and 64% when all patients were combined. We achieved an accuracy of 78% by integrating functional data and 79% by integrating structural data for left mTLE, and the highest accuracy of 84% was obtained when all functional and structural measures were combined. These findings suggest that combining multimodal measures within a single model is a promising direction for improving the classification of individual patients with mTLE.
