Learning Feature Hierarchies via Regression Trees


Learning Feature Hierarchies via Regression Trees – As the quality of information grows, so too does the need for a reliable way to classify. In this paper, we propose a novel method to perform classification in the form of a probabilistic model that estimates a latent covariance matrix from multiple input features. By this means, the model is an implicit model that we can use to automatically classify nonlinear structures while being flexible to accommodate complex inputs. Specifically, we propose a probabilistic inference algorithm that automatically estimates the latent covariance matrix as the output of a robust estimator. Experimental results demonstrate the effectiveness of our model in tasks with a variety of input features ranging from visual and motor scenes, to biomedical applications.

It is argued that continuous programming language models are highly effective for modelling structured systems. The language models have proved to be very promising for modeling time series. Here we propose a method for modeling continuous and continuous-valued time series in continuous programming language models by approximating time series by a polynomial transformation. The proposed method is equivalent to the convex convex method of Mervinari and Linnaean (2009). We show that our method is much more accurate than Mervinari and Linnaean’s approach (2009, 2010). Furthermore, we prove that the proposed algorithm is comparable to the algorithm for time series model estimation.
