In the proposed algorithm, Laplacian eigenmaps are used to reconstruct the objective function of dimensionality reduction. The weights of it are introduced by combining the geodesic distance with Euclidean distance, which can effectively represent the manifold structure of nonlinear data. Compared the existing LLE algorithm, the proposed one better maintains the original manifold structure of the data. The merit of the proposal is enhanced by the theoretical analysis and numerical experiments, where the classification recognition rate is 2%\u20138% higher than LLE.<\/jats:p>","DOI":"10.3233\/kes-190132","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T13:16:41Z","timestamp":1611062201000},"page":"323-330","source":"Crossref","is-referenced-by-count":0,"title":["Improved weighted local linear embedding algorithm based on Laplacian eigenmaps"],"prefix":"10.1177","volume":"24","author":[{"given":"Qing","family":"Wu","sequence":"first","affiliation":[{"name":"School of Automation, Xi\u2019an University of Posts and Telecommunications, Xi\u2019an, Shaanxi, China"},{"name":"Xi\u2019an Key Laboratory of Advanced Control and Intelligent Process, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rongrong","family":"Jing","sequence":"additional","affiliation":[{"name":"School of Automation, Xi\u2019an University of Posts and Telecommunications, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"En","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Humanities and Social Sciences, Xi\u2019an Jiaotong University, Xi\u2019an, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"4","key":"10.3233\/KES-190132_ref1","doi-asserted-by":"crossref","first-page":"813","DOI":"10.1134\/S1054661818040041","article-title":"An adaptive entropy based scale invariant face recognition face altered by plastic surgery","volume":"28","author":"Sable","year":"2018","journal-title":"Pattern Recognition and Image Analysis"},{"key":"10.3233\/KES-190132_ref2","doi-asserted-by":"crossref","unstructured":"A.M.
