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 ..."

Sequence Alignment, Mutual Information, and Dissimilarity Measures for Constructing Phylogenies

by Orion Penner, Peter Grassberger, Maya Paczuski
"... Background: Existing sequence alignment algorithms use heuristic scoring schemes based on biological expertise, which cannot be used as objective distance metrics. As a result one relies on crude measures, like the p- or log-det distances, or makes explicit, and often too simplistic, a priori assump ..."

assumptions about sequence evolution. Information theory provides an alternative, in the form of mutual information (MI). MI is, in principle, an objective and model independent similarity measure, but it is not widely used in this context and no algorithm for extracting MI from a given alignment (without

A Grouping Principle and Four Applications

by Agnè S Desolneux , Lionel Moisan , Jean-Michel Morel - IEEE Transactions on Pattern Analysis and Machine Intelligence , 2003
"... Abstract-Wertheimer's theory suggests a general perception law according to which objects having a quality in common get perceptually grouped. The Helmholtz principle is a quantitative version of this general grouping law. It states that a grouping is perceptually "meaningful" if its ..."

;meaningful" if its number of occurrences would be very small in a random situation: Geometric structures are then characterized as large deviations from randomness. In two previous works, we have applied this principle to the detection of orientation alignments and boundaries in a digital image. In this paper, we

Multiresolution Image Registration Based on Kullback-Leibler Distance

by Rui Gan, Jue Wu, Albert C. S. Chung, Simon C. H. Yu, William M. Wells Iii - In The 7th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI’04 , 2004
"... This paper extends our prior work on multi-modal image registration based on the a priori knowledge of the joint intensity distribution that we expect to obtain, and Kullback-Leibler distance. This expected joint distribution can be estimated from pre-aligned training images. Experimental result ..."

results show that, as compared with the Mutual Information and Approximate Maximum Likelihood based registration methods, the new method has longer capture range at di#erent image resolutions, which can lead to a more robust image registration method.

Universidad de Barcelona

by Vicenç Quera, Roger Bakeman, Augusto Gnisci
"... When sequences of discrete events, or other units, are independently coded by two coders using a set of mutually exclusive and exhaustive codes, but onset times are not preserved, it is often unclear how pairs of protocols should be aligned, yet such alignment is required before Cohen’s kappa, a com ..."

by Bailu Si, Emilio Kropff Aless, Ro Treves, B. Si, A. Treves, E. Kropff, A. Treves , 2011
"... Abstract The spatial responses of many of the cells recorded in all layers of rodent medial entorhinal cortex (mEC) show mutually aligned grid patterns. Recent experimental findings have shown that grids can often be better described as elliptical rather than purely circular and that, beyond the mut ..."

Medical Image Registration by Minimizing Divergence Measure Based on Tsallis Entropy

by Shaoyan Sun, Liwei Zhang, Chonghui Guo
"... Abstract—As the use of registration packages spreads, the number of the aligned image pairs in image databases (either by manual or automatic methods) increases dramatically. These image pairs can serve as a set of training data. Correspondingly, the images that are to be registered serve as testing ..."
Abstract - Add to MetaCart
that, compared with the widely-used Shannon mutual information as well as Tsallis mutual information, the proposed method is computationally more efficient without sacrificing registration accuracy. Keywords—Multimodality images, image registration, Shannon entropy, Tsallis entropy, mutual information

"... It has been argued that, as a distinctive human trait, mimicry is involved in many aspects of human social interaction, such as coordination and learning, cultural evolution, and group cohesion (Chartrand & van Baaren, 2009; Mesoudi, 2009; Tomasello, 1999). Likewise, mimicry is a characteristic ..."
