We define a probability distribution over equivalence classes of binary matrices with a finite number of rows and an unbounded number of columns. This distribution is suitable for use as a prior in probabilistic models that represent objects using a potentially infinite array of features. We identify a simple generative process that results in the same distribution over equivalence classes, whi...

Abstract: The purpose of this work is to describe a unified, and indeed simple, mechanism for non-parametric Bayesian analysis, construction and generative sampling of a large class of latent feature models which one can describe as generalized notions of Indian Buffet Processes (IBP). This is done via the Poisson Process Calculus as it now relates to latent feature models. The IBP, first arisi...

Inference for latent feature models is inherently difficult as the inference space grows exponentially with the size of the input data and number of latent features. In this work, we use Kurihara & Welling (2008)’s maximization-expectation framework to perform approximate MAP inference for linearGaussian latent feature models with an Indian Buffet Process (IBP) prior. This formulation yields a ...

During his development of the germ theory of disease, Louis Pasteur compared cholera and anthrax infections and remarked “Quelle différence donc entre le vibrion septique et cette bactéridie, et n’est-il pas remarquable de voir se multiplier dans 1=organization animale des êtres aussi dissemblables par leur mode de nutrition!” (1). An abridged English translation of this phrase reads “So what’s...

A comparative study is performed on three different approaches for prediction of transonic buffet onset infinite swept wings. All are based the unsteady Reynolds-averaged Navier–Stokes (URANS) equations, and include: quasi-3D fully-3D global stability analysis corresponding steady 2.5D RANS solutions direct numerical solution 3D URANS equations. The results presented an wing ONERA OAT15A airfoi...

Recent achievements in the application of activematerials induced-strain actuation to counteract aeroelastic and vibration effects in helicopters and fixed wing aircraft are reviewed. First, the induced-strain actuation principles and capabilities are briefly presented. Next, the attention is focused on the smart rotor blade applications. Induced twist, active blade tip, and active blade flap a...

Count data arises for example in bioinformatics or analysis of text documents represented as word count vectors. With several data sets available from related sources, exploiting their similarities by transfer learning can improve models compared to modeling sources independently. We introduce a Bayesian generative transfer learning model which represents similarity across document collections ...
