Structural Concrete, EarlyView.Abstract Our generation inherits this cultural heritage of historic material and historic reinforced concrete structures and thus bears a certain responsibility to preserve these historic buildings with the help of the new technologies of lifetime management, conservation concepts and the new digitalization as well as the emerging safety concepts of ...

Dirichlet Posterior Sampling with Truncated Multinomial Likelihoods [PDF]
, 2012 We consider the problem of drawing samples from posterior distributions formed under a Dirichlet prior and a truncated multinomial likelihood, by which we mean a Multinomial likelihood function where we condition on one or more counts being zero a priori.

Approximate Bayesian Computation for a Class of Time Series Models [PDF]
, 2014 In the following article we consider approximate Bayesian computation (ABC) for certain classes of time series models. In particular, we focus upon scenarios where the likelihoods of the observations and parameter are intractable, by which we mean that ...

A hidden semi-Markov model for estimating burst suppression EEG [PDF]
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019 Burst suppression is an electroencephalogram (EEG) pattern associated with profoundly inactivated brain states characterized by cerebral metabolic depression. This pattern is distinguished by short-duration band-limited electrical activity (bursts) interspersed between relatively near-isoelectric periods (suppressions).

Unsupervised Work Behavior Pattern Extraction Based on Hierarchical Probabilistic Model
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.In this study, we address the challenge of analyzing worker behaviors in high‐mix, low‐volume production environments, where traditional supervised learning methods struggle owing to the lack of labeled data and task variability among workers. To overcome these issues, we propose a novel hierarchical approach for unsupervised behavior pattern ...

Route Restoring Based on Hidden Semi-Markov Model
Advances in Intelligent Systems Research, 2014 Present raw geo-tagged photo routes cannot provide information as enough as complete GPS trajectories due to the defects hidden in them. This paper mainly aims at analyzing the large amounts of geo-tagged photos and proposing a novel travel route restoring method. In our approach we apply the Hidden SemiMarkov model and Mean Value method to demonstrate

Global Policy, EarlyView.ABSTRACT Lethal Autonomous Weapons Systems (LAWS) have the potential to dramatically alter modern warfare and reshape global power differentials. Despite the strong rationale for negotiating global rules, consensus on whether and how to regulate LAWS has yet to be reached.

Movement Ecology, 2023 Background State-space models, such as Hidden Markov Models (HMMs), are increasingly used to classify animal tracks into behavioural states. Typically, step length and turning angles of successive locations are used to infer where and when an animal is ...

Bootstrapping Information Extraction from Field Books [PDF]
, 2008 We present two machine learning approaches to information extraction from semi-structured documents that can be used if no annotated training data are available, but there does exist a database filled with information derived from the type of documents ...

Inferring broken detailed balance in the absence of observable currents [PDF]
, 2019 Identifying dissipation is essential for understanding the physical mechanisms underlying nonequilibrium processes. {In living systems, for example, the dissipation is directly related to the hydrolysis of fuel molecules such as adenosine triphosphate ...
