Conditional density estimation with dimensionality reduction via squared-loss conditional entropy minimization.

Neural computation
Regression aims at estimating the conditional mean of output given input. However, regression is not informative enough if the conditional density is multimodal, heteroskedastic, and asymmetric. In such a case, estimating the conditional density itse...

Graph degree sequence solely determines the expected hopfield network pattern stability.

Neural computation
We analyze the effect of network topology on the pattern stability of the Hopfield neural network in the case of general graphs. The patterns are randomly selected from a uniform distribution. We start the Hopfield procedure from some pattern v. An e...

Clinical prediction from structural brain MRI scans: a large-scale empirical study.

Neuroinformatics
Multivariate pattern analysis (MVPA) methods have become an important tool in neuroimaging, revealing complex associations and yielding powerful prediction models. Despite methodological developments and novel application domains, there has been litt...
