Structured Priors for Structure Learning

open access: yesCoRR, 2012
Traditional approaches to Bayes net structure learning typically assume little regularity in graph structure other than sparseness. However, in many cases, we expect more systematicity: variables in real-world systems often group into classes that predict the kinds of probabilistic dependencies they participate in.

Multiple conformations facilitate PilT function in the type IV pilus

open access: yesNature Communications, 2019
Bacterial type IV pilus-like systems catalyse the formation of pilin fibres but it is unknown how they are powered. Here, the authors present crystal and cryo-EM structures of the hexameric motor ATPases PilB and PilT from Type IVa Pilus that reveal ...

Hybrid Optimization Algorithm for Bayesian Network Structure Learning

open access: yesInformation, 2019
Since the beginning of the 21st century, research on artificial intelligence has made great progress. Bayesian networks have gradually become one of the hotspots and important achievements in artificial intelligence research.

Multiscale causal structure learning [PDF]

open access: yes, 2023
Causal structure learning methods are vital for unveiling causal relationships embedded into observed data. However, the state of the art suffers a major limitation: it assumes that causal interactions occur only at the frequency at which data is ...

Bayesian Learning of Markov Network Structure [PDF]

open access: yes, 2006
We propose a simple and efficient approach to building undirected probabilistic classification models (Markov networks) that extend naive Bayes classifiers and outperform existing directed probabilistic classifiers (Bayesian networks) of similar ...

Structure Learning via Parameter Learning [PDF]

open access: yesProceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management, 2014
A key challenge in information and knowledge management is to automatically discover the underlying structures and patterns from large collections of extracted information. This paper presents a novel structure-learning method for a new, scalable probabilistic logic called ProPPR.

Structured Apprenticeship Learning [PDF]

open access: yes, 2012
We propose a graph-based algorithm for apprenticeship learning when the reward features are noisy. Previous apprenticeship learning techniques learn a reward function by using only local state features. This can be a limitation in practice, as often some features are misspecified or subject to measurement noise.

Learning the Structure of Event Sequences [PDF]

open access: yesJournal of Experimental Psychology: General, 1990
How is complex sequential material acquired, processed, and represented when there is no intention to learn? Two experiments exploring a choice reaction time task are reported. Unknown to Ss, successive stimuli followed a sequence derived from a "noisy" finite-state grammar.

Inducing structure in reward learning by learning features

open access: yesThe International Journal of Robotics Research, 2022
Reward learning enables robots to learn adaptable behaviors from human input. Traditional methods model the reward as a linear function of hand-crafted features, but that requires specifying all the relevant features a priori, which is impossible for real-world tasks.

Learning Latent Jet Structure [PDF]

open access: yesSymmetry, 2021
We summarize our recent work on how to infer on jet formation processes directly from substructure data using generative statistical models. We recount in detail how to cast jet substructure observables’ measurements in terms of Bayesian mixed membership models, in particular Latent Dirichlet Allocation.
