CLinearLocalTangentSpaceAlignment Class Reference

---

Detailed Description

LinearLocalTangentSpaceAlignment converter used to construct embeddings as described in:

Zhang, T., Yang, J., Zhao, D., & Ge, X. (2007). Linear local tangent space alignment and application to face recognition. Neurocomputing, 70(7-9), 1547-1553. Retrieved from http://linkinghub.elsevier.com/retrieve/pii/S0925231206004577

This method is hardly applicable to very high-dimensional data due to necessity to solve eigenproblem involving matrix of size (dim x dim).
