Maximum A Posteriori Inference in Sum-Product Networks

open access: yes, 2017
Sum-product networks (SPNs) are a class of probabilistic graphical models that allow tractable marginal inference. However, the maximum a posteriori (MAP) inference in SPNs is NP-hard.

Spatial validation reveals poor predictive performance of large-scale ecological mapping models

open access: yesNature Communications, 2020
Mapping ecological variables using machine-learning algorithms based on remote-sensing data has become a widespread practice in ecology. Here, the authors use forest biomass mapping as a study case to show that the most common model validation approach ...

Enhancing the Transferability of Adversarial Patch via Alternating Minimization

open access: yesInternational Journal of Computational Intelligence Systems
Adversarial patches, a type of adversarial example, pose serious security threats to deep neural networks (DNNs) by inducing erroneous outputs. Existing gradient stabilization methods aim to stabilize the optimization direction of adversarial examples ...

Matrix Product States for Interacting Particles without Hardcore Constraints

open access: yes, 2017
We construct matrix product steady state for a class of interacting particle systems where particles do not obey hardcore exclusion, meaning each site can occupy any number of particles subjected to the global conservation of total number of particles in
