Latent State Inference in a Spatiotemporal Generative Model

چکیده
Knowledge about the hidden factors that determine particular system dynamics is crucial for both explaining them and pursuing goal-directed interventions. Inferring these from time series data without supervision remains an open challenge. Here, we focus on spatiotemporal processes, including wave propagation weather dynamics, which assume universal causes (e.g. physics) apply throughout space time. A recently introduced DIstributed SpatioTemporal graph Artificial Neural network Architecture (DISTANA) used enhanced to learn such requiring fewer parameters achieving significantly more accurate predictions compared temporal convolutional neural networks other related approaches. We show DISTANA, when combined with a retrospective latent state inference principle called active tuning, can reliably derive location-respective causal factors. In current prediction benchmark, DISTANA infers our planet’s land-sea mask solely by observing temperature and, meanwhile, uses self inferred information improve its own future predictions.

A Probabilistic Generative Model for Latent Business Networks Mining
The structural embeddedness theory posits that a company’s embeddedness in a business network impacts its competitive performance. This highlights the theoretical and practical values toward business network mining and analysis. Given the fact that latent business relationships exist among companies, and these relationships continuously evolve over time, a manual approach for the discovery and ...
متن کاملA Latent Variable Model for Generative Dependency Parsing
We propose a generative dependency parsing model which uses binary latent variables to induce conditioning features. To define this model we use a recently proposed class of Bayesian Networks for structured prediction, Incremental Sigmoid Belief Networks. We demonstrate that the proposed model achieves state-of-the-art results on three different languages. We also demonstrate that the features ...
متن کاملBayesian inference for smoking cessation with a latent cure state.
We present a Bayesian approach to modeling dynamic smoking addiction behavior processes when cure is not directly observed due to censoring. Subject-specific probabilities model the stochastic transitions among three behavioral states: smoking, transient quitting, and permanent quitting (absorbent state). A multivariate normal distribution for random effects is used to account for the potential...
متن کاملCeleste: Variational inference for a generative model of astronomical images
We present a new, fully generative model of optical telescope image sets, along with a variational procedure for inference. Each pixel intensity is treated as a Poisson random variable, with a rate parameter dependent on latent properties of stars and galaxies. Key latent properties are themselves random, with scientific prior distributions constructed from large ancillary data sets. We check o...
متن کاملDeep Part-Based Generative Shape Model with Latent Variables
The Shape Boltzmann Machine (SBM) [6] and its multilabel version MSBM [5] have been recently introduced as deep generative models that capture the variations of an object shape. While being more flexible MSBM requires datasets with labeled parts of the objects for training. In the paper we present an algorithm for training MSBM using binary masks of objects and the seeds which approximately cor...
