Incremental Probabilistic Inference

چکیده

Propositional representation services such as truth maintenance systems offer pow­ erful support for incremental, interleaved, problem-model construction and evaluation. Probabilistic inference systems, in contrast, have lagged behind in supporting this incre­ mentality typically demanded by problem­ solvers. The problem, we argue, is that the basic task of probabilistic inference is typi­ cally formulated at too large a grain-size. We show how a system built around a smaller grain-size inference task can have the desired incrementality and serve as the basis for a low-level (propositional) probabilistic repre­ sentation service.

Probabilistic Type Theory for Incremental Dialogue Processing

We present an adaptation of recent work on probabilistic Type Theory with Records (Cooper et al., 2014) for the purposes of modelling the incremental semantic processing of dialogue participants. After presenting the formalism and dialogue framework, we show how probabilistic TTR type judgements can be integrated into the inference system of an incremental dialogue system, and discuss how this ...

Incrementalizing MCMC in Probabilistic Programs Through Tracing and Slicing

Probabilistic programming enables high-level specification of complex probabilistic models without the need for hand-built inference techniques. We present a dynamic compilation technique for increasing the efficiency of Markov Chain Monte Carlo (MCMC) inference on probabilistic programs. We focus on Church, a probabilistic extension of untyped call-by-value lambda calculus. MCMC in this settin...

Probabilistic Record Type Lattices for Incremental Reference Processing

This chapter addresses the issue of incorporating probabilistic type-theoretic inference into an incremental dialogue framework, using processing of referring expressions (that is, their interpretation and generation) as a test case. Within our framework, we model reference processing in a psycholinguistically plausible way– that is, in a strictly left-to-right, word-by-word, incremental fashio...

Probabilistic Programming Language and its Incremental Evaluation

This system description paper introduces the probabilistic programming language Hakaru10, for expressing, and performing inference on (general) graphical models. The language supports discrete and continuous distributions, mixture distributions and conditioning. Hakaru10 is a DSL embedded in Haskell and supports Monte-Carlo Markov Chain (MCMC) inference. Hakaru10 is designed to address two main...

Efficient Query Evaluation over Temporally Correlated Probabilistic Streams

Many real world applications such as sensor networks and other monitoring applications naturally generate probabilistic streams that are highly correlated in both time and space. Query processing over such streaming data must be cognizant of these correlations, since they significantly alter the final query results. Several prior works have suggested approaches to handling correlations in proba...
