Abstract:
Inspired by the development in modern data science, a shift is increasingly visible in the foundation of statistical inference, away from a real space, where random variables reside, toward a nonmetrized and nonordinal alphabet, where more general random elements reside. While statistical inferences based on random variables are theoretically well supported in the rich literature of probability and statistics, inferences on alphabets, mostly by way of various entropies and their estimation, are less systematically supported in theory. Without the familiar notions of neighborhood, real or compl

Abstract:
Shape restrictions have played a central role in economics as both testable implications of theory and sufficient conditions for obtaining informative counterfactual predictions. In this paper, we provide a general procedure for inference under shape restrictions in identified and partially identified models defined by conditional moment restrictions. Our test statistics and proposed inference methods are based on the minimum of the generalized method of moments (GMM) objective function with and without shape restrictions. Uniformly valid critical values are obtained through a bootstrap proced

Abstract:
Two recent strands of the structural vector autoregression literature use higher moments for identification, exploiting either non-Gaussianity or heteroskedasticity. These approaches achieve point identification without exclusion or sign restrictions. We review this work critically and contrast its goals with the separate research program that has pushed for macroeconometrics to rely more heavily on credible economic restrictions. Identification from higher moments imposes stronger assumptions on the shock process than second-order methods do. We recommend that these assumptions be tested. Sin

Abstract:
Purpose Studies investigating the ability of children with language impairment (LI) to infer emotions rely on verbal responses (which can be challenging for these children) and/or the selection of a card representing an emotion (which limits the response range). In contrast, a drawing task might allow a broad spectrum of responses without involving language. This study used a drawing task to compare the ability to make emotional inferences in children with and without LI. Method Twenty-two children with LI and 22 typically developing children ages 6 to 10 years were assessed in school during 3

Abstract:
The coupling of individual models in terms of end-to-end calculations for unit operations in manufacturing processes is a challenging task. We present a probability distribution-based approach for the combined outcomes of parametric and non-parametric models. With this so-called Bayesian predictive ensemble, the statistical moments such as mean value and standard deviation can be accurately computed without any further approximation. It is shown that the ensemble of different model predictions leads to an uninformed prior distribution, which can be transformed into a predictive posterior distr

The problem of test synthesis for fuzzy automata with finite memory is considered. The paper is based on the results obtained by the author earlier. They study linear automata (LA), a subclass of which are automata with finite memory (AFM). Both types of automata are used as models in diagnostics of discrete devices and in other applications. The advantages of LA are simplicity of realization and availability of developed mathematical apparatus for their study.

Abstract This article considers the problem of testing many moment inequalities where the number of moment inequalities, denoted by $p$, is possibly much larger than the sample size $n$. There is a variety of economic applications where solving this problem allows to carry out inference on causal and structural parameters; a notable example is the market structure model of Ciliberto and Tamer (2009) where $p=2^{m+1}$ with $m$ being the number of firms that could possibly enter the market.

This paper discusses the direct perception of an unknown object and the action decision to grasp an unknown object using depth sensor for social robots. Conventional methods estimate the accurate physical parameters when a robot wants to grasp an unknown object. Therefore, we propose a perceptual system based on an invariant concept in ecological psychology, which perceives the information relevant to the action of the robot. Firstly, we proposed the plane detection based approach for perceiving an unknown object. In this paper, we propose the sensation of grasping which is expressed by using

"existing code correlating a whistle with the information that now is the moment to attack. The information is obvious enough: it is the only information that A could conceivably have intended to make manifest in the circumstances. Could not the repetition of such a situation lead to the development of a code? Imagine that the two prisoners, caught again, find themselves in the same predicament: again a whistle, again an escape, and again they are caught. The next time, prisoner B, who has not realised that both guards are distracted, hears pris-oner A whistle: this time, fortunately, B does not have to infer what the whistle is intended to make manifest: he knows. The whistle has become a signal associ-ated by an underlying code to the message ‘Let us overpower our guards now!’ Inferential theorists might be tempted to see language as a whole as having developed in this way: to see conventional meanings as growing out of natural inferences. This is reminiscent of the story of how Rockefeller became a million-aire. One day, when he was young and very poor, Rockefeller found a one-cent coin in the street. He bought an apple, polished it, sold it for two cents, bought two apples, polished them, sold them for four cents . . . After one month he bought a cart, after two years he was about to buy a grocery store, when he inherited the fortune of his millionaire uncle. We will never know how far hominid efforts at conventionalising inference might have gone towards establishing a full-fledged human language. The fact is that the development of human languages was made possible by a specialised biological endowment. Whatever the origin of the language or code employed, a piece of coded behaviour may be used ostensively – that is, to provide two layers of information: a basic layer of information, which may be about anything at all, and a second layer con-sisting of the information that the first layer of information has been intentionally made manifest. When a coded signal, or any other arbitrary piece of behaviour, is used ostensively, the evidence displayed bears directly on the individual’s intention, and only indirectly on the basic layer of information that she intends to make manifest. We are now, of course, dealing with standard cases of Gricean communication. Is there a dividing line between instances of ostension which one would be more inclined to describe as ‘showing something’, and clear cases of communica-tion where the communicator unquestionably ‘means something’? One of Grice’s main concerns was to draw such a line: to distinguish what he called ‘natural meaning’ – smoke meaning fire, clouds meaning rain, and so on – from ‘non-natural meaning’: the word ‘fire’ meaning fire, Peter’s utterance meaning that it will rain, and so on. Essential to this distinction was the third type of communi-cator’s intention Grice mentioned in his analysis: a true communicator intends the recognition of his informative intention to function as at least part of the audi-ence’s reason for fulfilling that intention. In other words, the first, basic, layer of information must not be entirely recoverable without reference to the second. What we have tried to show so far in this section is that there are not two distinct and well-defined classes, but a continuum of cases of ostension ranging from ‘showing’, where strong direct evidence for the basic layer of information is provided, to ‘saying that’, where all the evidence is indirect.

Abstract We combine a thermoacoustic experiment with a thermoacoustic reduced order model using Bayesian inference to accurately learn the parameters of the model, rendering it predictive. The experiment is a vertical Rijke tube containing an electric heater. The heater drives a base flow via natural convection, and thermoacoustic oscillations via velocity-driven heat release fluctuations. The decay rates and frequencies of these oscillations are measured every few seconds by acoustically forcing the system via a loudspeaker placed at the bottom of the tube.

Abstract:
Conflict resolution is the control decision process, which should be taken as a result of the firing among several fuzzy behavior rules. In the Behavior-based Robot Navigation System, control of a robot is shared between a set of perception-action units, called behaviors selection. In other words, the behavior selection is the way that an agent selects the most appropriate or the most relevant next action to take at a particular moment, when facing a particular problem. Based on selective sensory information, each behavior produces immediate reaction to control the robot with respect to a part
