This paper addresses the estimation of the latent dimensionality in nonnegative matrix factorization (NMF) with the \beta-divergence. ...
We propose a Bayesian model based on automatic relevance determination in which the columns of the dictionary matrix and the rows of the activation matrix are tied together through a common scale parameter ...

In this paper, we propose a nonlinear matrix factorization method with the priors of inter-and intra-correlations among images and tags to effectively predict the tag relevance to the visual contents. ...
Similarly, we can obtain the top relevant images corresponding to any tag so as to perform the task of image search by keywords. ...
Unlike the existing matrix factorization work, this paper proposes a nonlinear matrix factorization approach with unified embedding (MFUE) to learn the tag relevance for social image retrieval. ...

In this paper, we consider the determination of the number of factors in nonnegative matrix factorization (NMF) for a zero-inflated data matrix. ...
This zero-inflated case leads to poor approximation to the nonnegative data matrix. ...
At the end of the algorithm, the effective factors are determined to be all mth factors such that the estimated relevance weight λ m are larger than the minimum (16). ...
