Efficient Causal Discovery and Abstraction in Perception Streams

چکیده

Human discovery of cause and effect in perception streams requires reliable online inference in highly unstructured noisy environments with very few (maybe even only one) positive examples. Automated causal discovery research, on the other hand, has typically operated in a qualitatively different setting: Data used for learning is cast into more static scenarios where all prospect observable causes are known in advance. Typically when learning it is assumed that all data is known (i.e., learning is done in batch mode), and little work has been done on the important but hard topic of causal abstraction. In this paper, we present a system that is a capable of wading through an unknown set of possible causes (events) in an online fashion to identify a small set of plausible candidates for some effect of interest. As new events are encountered, they can be added to the system in an online fashion. We provide a mechanism to learn arbitrary noisy logic formulae and present a method to do causal abstraction.

Causal Induction 1 Running head : Continuous Causal Inference Causal Induction from Continuous Event Streams

Three experiments investigated the impact of delay on human causal learning. We present a new paradigm based on the presentation of continuous event streams, and use it to test two hypotheses drawn from associative learning theories of causal inference. Unlike free-operant procedures traditionally used to study temporal aspects of causal learning (Shanks, Pearson, & Dickinson, 1989; Shanks & Di...

The Asymmetric Effects of Tax Revenues on Government Expenditures in Iran

The tax-expenditure hypothesis posed by Milton Friedman emphasizes a positive causal relationship between government tax revenues and government expenditures. If citizens do not have a correct perception of the real tax burden and under-estimate the price of public goods and services, there is a negative causal relationship between tax revenues and government expenditures, which indicates exist...

Causal Discovery from Changes: a Bayesian Approach

We propose a new method of discovering causal structures, based on the detection of local, spontaneous changes in the underlying data-generating model. We derive expressions for the Bayesian score that a causal structure should obtain from streams of data produced by locally changing distributions. Simulation experiments indicate that dynamic information may improve the power of discovery up to...

Proposing a causal model of body image perception with eating disorders by depression mediation in Iranian youth

The purpose of this study was to determine the causal relationship between eating disorders and body image perception mediated by depression in youth. The research sample consisted of 200 Khouzestan Science and Research University freshman students during 2003-2004 academic year, who ranged in age between 35 and 24 years old. Given that there were seven paths in the model, the number of partici...
