    Zhu Xi’s Method of Phonetic Annotation in Ancient Chinese Books

    Zhu Xi is not only a master of Confucianism, but also has made great achievements in exegesis. By studying Zhu Xi’s exegetical thoughts and methods in the practice of exegesis, we can correctly evaluate Zhu Xi’s historical position in the history of Chinese exegesis.This article discusses Zhu Xi’s methods of phonetic annotation, including Zhi Yin (direct sound), Bi Kuang (comparison), Fan Qie (recomposition), Bie Si Sheng and Biao Ru Zi (four tones) and Xie Yin (rhyme) in exegesis of ancient books. These annotations retain the actual phonetics of the Song Dynasty and are very important for studies of Chinese phonetics history

    Bounded Coordinate-Descent for Biological Sequence Classification in High Dimensional Predictor Space

    Full text link
    We present a framework for discriminative sequence classification where the learner works directly in the high dimensional predictor space of all subsequences in the training set. This is possible by employing a new coordinate-descent algorithm coupled with bounding the magnitude of the gradient for selecting discriminative subsequences fast. We characterize the loss functions for which our generic learning algorithm can be applied and present concrete implementations for logistic regression (binomial log-likelihood loss) and support vector machines (squared hinge loss). Application of our algorithm to protein remote homology detection and remote fold recognition results in performance comparable to that of state-of-the-art methods (e.g., kernel support vector machines). Unlike state-of-the-art classifiers, the resulting classification models are simply lists of weighted discriminative subsequences and can thus be interpreted and related to the biological problem

    Quantum-State Engineering of Multiple Trapped Ions for Center-of-Mass Mode

    Full text link
    We propose a scheme to generate a superposition with arbitrary coefficients on a line in phase space for the center-of-mass vibrational mode of N ions by means of isolating all other spectator vibrational modes from the center-of-mass mode. It can be viewed as the generation of previous methods for preparing motional states of one ion. For large number of ions, we need only one cyclic operatin to generate such a superposition of many coherent states.Comment: 14 pages, revte

    Beyond Gr\"obner Bases: Basis Selection for Minimal Solvers

    Full text link
    Many computer vision applications require robust estimation of the underlying geometry, in terms of camera motion and 3D structure of the scene. These robust methods often rely on running minimal solvers in a RANSAC framework. In this paper we show how we can make polynomial solvers based on the action matrix method faster, by careful selection of the monomial bases. These monomial bases have traditionally been based on a Gr\"obner basis for the polynomial ideal. Here we describe how we can enumerate all such bases in an efficient way. We also show that going beyond Gr\"obner bases leads to more efficient solvers in many cases. We present a novel basis sampling scheme that we evaluate on a number of problems
