A novel non-linear dimensionality reduction
method, called Temporal Laplacian Eigenmaps, is introduced
to process efficiently time series data. In this embedded-based
approach, temporal information is intrinsic to the objective
function, which produces description of low dimensional spaces
with time coherence between data points. Since the proposed
scheme also includes bidirectional mapping between data and
embedded spaces and automatic tuning of key parameters, it
offers the same benefits as mapping-based approaches. Experiments on a couple of computer vision applications demonstrate
the superiority of the new approach to other dimensionality
reduction method in term of accuracy. Moreover, its lower
computational cost and generalisation abilities suggest it is
scalable to larger datasets.
