- Abstract:
-
Canonical correlation analysis (CCA) is a statistical technique commonly used to determine the correlativity of two variables. It is difficult to accurately identify the complex underlying relationship between variables using linear CCA, so we propose a nonlinear CCA based on an extreme learning machine (ELM) for multi-modal feature extraction. First, to obtain abstract-depth feature representation, we use the ELM to perform unsupervised feature learning for each modality. Then, we use CCA to maximize the correlation between the nonlinear representations, thereby simultaneously obtaining two groups of related variables, and realize complex nonlinear and high-correlation representations of multi-modality data. Lastly, we conducted an experiment using the Cornell grasping dataset. The results show that, in comparison with other related algorithms, the proposed method significantly increases the training speed.
