Descripción
Facial expression recognition is a topic of interest both in industry and academia. Recent approaches to facial expression recognition are based on mapping ex- pressions to low dimensional manifolds. In this paper we revisit various dimensionality reduction algorithms using a graph-based paradigm. We compare eight di- mensionality reduction algorithms on a facial expres- sion recognition task. For this task, experimental re- sults show that although Linear Discriminant Analysis (LDA) is the simplest and oldest supervised approach, its results are comparable to more flexible recent algo- rithms. LDA, on the other hand, is much simpler to tune, since it only depends on one parameter.
