A variational nonlinear Hausdorff-Young inequality in the discrete setting [PDF]
arXiv, 2017 Following the works of Lyons and Oberlin, Seeger, Tao, Thiele and Wright, we relate the variation of certain discrete curves on the Lie group $\text{SU}(1,1)$ to the corresponding variation of their linearized versions on the Lie algebra. Combining this with a discrete variational Menshov-Paley-Zygmund theorem, we establish a variational Hausdorff ...

Precompactness in bivariate metric semigroup-valued bounded variation spaces [PDF]
arXivIn this paper, we show that if a set in bivariate metric semigroups-valued bounded variation spaces is pointwise totally bounded and joint equivariated then it is precompact. These spaces include bounded Jordan variation spaces, bounded Wiener variation spaces, bounded Waterman variation spaces, bounded Riesz variation spaces and bounded Korenblum ...

The total second variation of Perelman's $\mathcal{W}$-functional [PDF]
arXiv, 2012 We show a very simple and general total second variation formula for Perelman's $\mathcal{W}$-functional at arbitrary points in the space of Riemannian metrics. Moreover we perform a study of the properties of the variations of K\"ahler structures.

Incremental Variational Inference for Latent Dirichlet Allocation [PDF]
arXiv, 2015 We introduce incremental variational inference and apply it to latent Dirichlet allocation (LDA). Incremental variational inference is inspired by incremental EM and provides an alternative to stochastic variational inference. Incremental LDA can process massive document collections, does not require to set a learning rate, converges faster to a local ...

Tutorial: Deriving the Standard Variational Autoencoder (VAE) Loss Function [PDF]
arXiv, 2019 In Bayesian machine learning, the posterior distribution is typically computationally intractable, hence variational inference is often required. In this approach, an evidence lower bound on the log likelihood of data is maximized during training. Variational Autoencoders (VAE) are one important example where variational inference is utilized.
