An Online Clustering Approach to Optimal Regression – We propose an online clustering technique for clustering data with multiple dimensions. Different datasets are often represented using a set of nodes (for example, an MRI image) and a set of labels. The dataset may contain multiple dimensions such as the dimension of noise, or it may be a set of images. The clustering algorithm, which we call Online Clustering Challenge, requires a set of parameters which are determined by our algorithms. We then learn the optimal solutions to each of these parameters and use them as the parameters of the clustering model. We validate this approach on several data clustering datasets. We present the results of our algorithms for each dataset that we evaluate on two datasets. The results show that our model is competitive with existing algorithms and we show that our algorithm is more flexible and accurate. Moreover, the algorithms we evaluate show that the algorithm does not take too many parameters and can be used to estimate the parameters of multiple datasets simultaneously.
We study unsupervised sparse estimation of the visual saliency maps via a graphical model. In this work, we propose a multi-class latent representation of the visual saliency maps using a variational algorithm, based on Monte Carlo sampling. The inference is performed on a sparse set of images from a dataset of real images to learn a sparse posterior representation of the saliency maps, and then the prediction is done via sparse sampling. Our approach is an extension of a Bayesian network learning framework that involves Bayesian Bayesian inference to the latent space to learn the posterior density of the visual saliency maps over a sparse distribution of latent images containing both the saliency maps and the training data. We show that the learned posterior density provides a good baseline for the latent saliency models to be used when training deep CNNs, and therefore can be used for the supervised and unsupervised learning of CNNs with high classification accuracy even without the latent space representation. The Bayesian model outperforms the supervised and unsupervised learning approaches by a very large margin.
