Learning by analogical bootstrapping

by Kenneth J. Kurtz, Chun-hui Miao, Dedre Gentner - Journal of the Learning Sciences , 2001
"... Analogies are typically drawn from a well-understood situation to a situation that is poorly understood. In this research, we investigate a different route to analogical insight. We suggest that mutual alignment-that is, comparison between 2 partially understood situations--can act to promote compre ..."

Low-Voltage CMOS Analog Bootstrapped Switch For Sample-and-Hold Circuit: Design and Chip Characterization

by Christian Jesus, B. Fayomi, Gordon W. Roberts, Mohamad Sawan
"... Abstract- This paper presents the design and characterization of a sample-and-hold circuit based on a novel implementation of the bootstrapped low-voltage analog CMOS switch. The heart of this circuit is a new low-voltage and low-stress CMOS clock voltage doubler. Through the use of a dummy switch, ..."

Bootstrapping the mind: Analogical processes and symbol systems

by Dedre Gentner - COGNITIVE SCIENCE , 2010
"... Human cognition is striking in its brilliance and its adaptability. How do we get that way? How do we move from the nearly helpless state of infants to the cognitive proficiency that characterizes adults? In this paper I argue, first, that analogical ability is the key factor in our prodigious capac ..."

Mutual bootstrapping between language and analogical processing

by Dedre Gentner, Stella Christie - LANGUAGE AND COGNITION, 2(2). 261-283 , 2010
"... What makes us so smart as a species, and what makes children such rapid learners? We argue that the answer to both questions lies in a mutual bootstrapping system comprised of (1) our exceptional capacity for relational cognition and (2) symbolic systems that augment this capacity. The ability to ca ..."

Principles of Marketing

by J. Scott Armstrong, Roderick J. Brodie , 1999
"... Research on forecasting is extensive and includes many studies that have tested alternative methods in order to determine which ones are most effective. We review this evidence in order to provide guidelines for forecasting for marketing. The coverage includes intentions, Delphi, role playing, conjo ..."

, conjoint analysis, judgmental bootstrapping, analogies, extrapolation, rule-based forecasting, expert systems, and econometric methods. We discuss research about which methods are most appropriate to forecast market size, actions of decision makers, market share, sales, and financial outcomes. In general

Maximum Likelihood and the Bootstrap for Nonlinear Dynamic Models

by Sílvia Gonçalves, Halbert White , 2002
"... We provide a uniÞed framework for analyzing bootstrapped extremum estimators of nonlinear dynamic models for heterogeneous dependent stochastic processes. We apply our results to the moving blocks bootstrap of Künsch (1989) and Liu and Singh (1992) and prove the Þrst order asymptotic validity of the ..."

of the bootstrap approximation to the true distribution of quasi-maximum likelihood estimators. We also consider bootstrap testing. In particular, we prove the Þrst order asymptotic validity of the bootstrap distribution of suitable bootstrap analogs of Wald and Lagrange Multiplier statistics for testing

Inconsistency of Bootstrap: the Grenander

by Bodhisattva Sen, Moulinath Banerjee, Michael Woodroofe , 2007
"... In this paper we investigate the (in)-consistency of different bootstrap methods for constructing confidence bands in the class of estimators that converge at rate cube-root n. The Grenander estimator (see Grenander (1956)), the nonparametric maximum likelihood estimator of an unknown non-increasing ..."

EL Inference for Partially Identified Models: Large Deviations Optimality and Bootstrap Validity

by Ivan A. Canay , 2008
"... This paper addresses the issue of optimal inference for parameters that are partially identified in models with moment inequalities. There currently exists a variety of inferential methods for use in this setting. However, the question of choosing optimally among contending procedures is unresolved. ..."
Abstract - Cited by 60 (5 self) - Add to MetaCart
. In this paper, I first consider a canonical large deviations criterion for optimality and show that inference based on the empirical likelihood ratio statistic is optimal. This finding is a direct analog to that in Kitamura (2001) for moment equality models. Second, I introduce a new empirical likelihood

Solving the 3d Ising model with the conformal bootstrap . . .

by Sheer El-Showk, Miguel F. Paulos, David Poland, Slava Rychkov, David Simmons-Duffin, Alessandro Vichi , 2014
"... We use the conformal bootstrap to perform a precision study of the operator spectrum of the critical 3d Ising model. We conjecture that the 3d Ising spectrum minimizes the central charge c in the space of unitary solutions to crossing symmetry. Because extremal solutions to crossing symmetry are uni ..."
