In 2013, an outbreak of gastrointestinal illness occurred following a buffet lunch at a restaurant in Canberra. An investigation was conducted to identify the cause of illness and to implement appropriate public health measures to prevent further disease. We conducted a retrospective cohort study via telephone interviews, using a structured questionnaire developed from the restaurant buffet men...

This paper presents a flexible topic model based on the nested Indian buffet process (nIBP). The flexibility is achieved by relaxing three constraints: (1) number of topics is fixed, (2) topics are independent, and (3) topic hierarchy for a document is limited by a single tree path. Bayesian nonparametric learning is conducted to build a tree model where the number of topics and the topic hiera...

This study experimentally investigates the effects of sweep angle and finite wing on transonic buffet, studying two-dimensional (2-D) three-dimensional configurations. Background-oriented schlieren stereographic particle image velocimetry (PIV) have been used as measurement techniques, performing experiments an OAT15A airfoil (clamped to both side windows wind tunnel), unswept wing, two swept w...

We propose the attraction Indian buffet distribution (AIBD), a for binary feature matrices influenced by pairwise similarity information. Binary are used in Bayesian models to uncover latent variables (i.e., features) that explain observed data. The process (IBP) is popular exchangeable prior matrices. In presence of additional information, however, exchangeability assumption not reasonable or ...

The objectives of this study are: 1) to learn the opinions entrepreneurs regarding adjustment buffet restaurant business in Bangkok under epidemic situation; 2) suggest a guideline for situation. used phenomenological research methodology by collecting data with in-depth interviews using semi-structured from key informants apply descriptive analysis. results showed that most pay more attention ...

In contrast to the efficiency-centric designs that are more prevalent today, we advocate a view of system design based on a holistic view of available resources. This view is embodied in what we call the Buffet principle: continue using additional resources as long as the marginal benefit is more than the marginal cost of using the resources. We illustrate through several examples how this seem...

The Indian Buffet Process is a versatile statistical tool for modeling distributions over binary matrices. We provide an efficient spectral algorithm as an alternative to costly Variational Bayes and sampling-based algorithms. We derive a novel tensorial characterization of the moments of the Indian Buffet Process proper and for two of its applications. We give a computationally efficient itera...
